a16z and Others Are Taking Over Seed Rounds: A Decade of Data from 20 Top VCs
If a16z and Sequoia have already entered the arena, does investing in seed funds still make sense?

TechFlow Insight: Mega-funds managing over $10 billion are flooding seed rounds at an unprecedented pace. Murph Capital pulled data from Harmonic to dissect the early-stage investment behavior of 20 top mega-funds across three eras—the SaaS era, the zero-interest-rate era, and the AI era. The conclusion isn’t simple: mega-funds’ seed-to-Series B conversion rates are indeed 3.7–4.2x the market average—but this advantage rapidly dilutes when they scale up deployment. Space remains for emerging managers—but only if they pick the right sectors.
A month ago, I posted a tweet asking a simple question: Are mega-funds truly taking over seed rounds—or does it just feel that way? After 65,000 views and hundreds of DMs, it was clear the question struck a nerve.
Emerging Managers (EMs) wrote in saying they felt the pressure but couldn’t quantify it; LPs asked: If a16z and Sequoia are already in seed, is investing in seed funds still meaningful? Even GPs at mega-funds themselves wanted to know how aggressively their peers were deploying capital at the earliest stages.
@pavelprata tweeted: Are mega-funds really taking over seed rounds? I decided to study the behavior of the world’s largest VC funds (AUM > $10B) at the earliest stage—to answer one simple question: Should EMs worry about losing their structural edge?
A broad consensus quickly emerged—and I largely agree:
- Mega-funds have indeed significantly increased their seed allocations—roughly tripling over the past decade.
- The market is large and fragmented enough that their share remains relatively small, concentrated mainly in the top quartile.
- Their core motivation isn’t immediate capital returns, but rather early access to talent, high signal-to-noise ratio data, and minimizing the risk of missing the next generational opportunity.
But consensus is just the starting point. Behind that broad trend lies a far more nuanced—and uneven—picture, invisible without data.
So we pulled data from Harmonic, collecting performance metrics from 20 mega-funds across three eras (SaaS, zero interest rate, AI), aiming to honestly answer: What’s *really* happening in the seed market? Where exactly are mega-funds headed? How is this affecting pricing? And do EMs truly have reason to worry?
Intuition vs. Data
First, the research framework.
We rely on public intelligence, supplemented by Harmonic’s real-time data (covering over 30 million companies and 190 million people). Chronologically, we analyze the past decade, segmented into three eras:
- SaaS Era (2015–2019): A five-year normal market cycle. Cloud, SaaS, marketplaces, and fintech dominated the narrative. Interest rates were normal, and markets exhibited discipline.
- Zero-Interest-Rate Era (2020–2022): A three-year period of near-zero interest rates. Capital was nearly free; investors flooded early-stage deals seeking returns. Tiger Global and SoftBank seemed to appear in every meaningful round. The seed market overheated severely—but chaotically, lacking structural logic.
- AI Era (2023–2026): From ChatGPT’s launch to today—a massive technological shock spawning an entirely new class of companies for which supersized seed rounds have become the norm.
Technically, we focus on seed rounds—but operationally include pre-seed and seed extensions. The reason is simple: boundaries between these early stages are often blurry or shifting; rigid segmentation would sacrifice honesty.
Now to the core. Frankly, even before launching this study, I held a strong intuition: mega-funds are appearing with increasing frequency on the radar of early-stage investors. This intuition stemmed largely from social media—logos of a16z, General Catalyst, and Sequoia increasingly appeared in seed announcements, each accompanied by high-profile media campaigns. Data confirms this:
- In the first half of 2026, a16z participated in ~48 seed rounds, leading 46% of them. This is a systematic seed strategy—not sporadic bets.
- Most striking is check size: the median for a16z-led rounds is $10.5M—more akin to a classic Series A than a traditional seed round.
- Adding General Catalyst and Sequoia, these three giants completed 87 seed deals in just 5.5 months, averaging one early-stage investment every 1.5 business days.
@a16z tweeted: We’re honored to lead Westmag’s seed round. One underappreciated advantage of investing across the full hardware stack is direct, firsthand exposure to supply chain challenges plaguing industrial infrastructure…
Meanwhile, Carta’s latest data shows seed valuations are inflating rapidly. While some may attribute this to a few aggressive players, most EM fund math still forces them to operate at or below the median to secure sufficient initial ownership and maintain viable return pathways.
Mega-funds operate under entirely different logic. With accumulated AUM, brand premium, and high-quality deal flow, price discipline is no longer a true constraint. This divergence is splitting the market into two distinct tiers—what we broadly term “classic seed” and “super seed”:
- The 90th percentile of seed valuations surged to $93.7M in Q1 2026—nearly doubling over four years.
- Over the past year, valuations above the median rose at least 53%.
- The bottom barely moved: The 25th percentile crept from $18M to $22.7M.
@PeterJ_Walker tweeted: Top 5% seed valuations now routinely exceed $175M—up 3x over the past 12 months. There’s just a hint of 2021 absurdity (even as an AI believer, I think so).
Yet all this remains indirect evidence—pointing toward a general direction but failing to deliver definitive answers on what’s *actually* happening in the early market, or how systemic mega-fund presence truly is.
That’s why we dug deeper. We analyzed each fund’s individual dynamics across the three eras, deconstructing their behavioral patterns—and what this shift ultimately means for EMs.
Dissecting the Deal Machine

Caption: Early-stage deal count comparison across three eras for 20 mega-funds
Averaging across the cohort, a typical mega-fund executed 10.6 early deals per year during the SaaS era. By the AI era, that jumped to 23.9 deals/year—a 2.37x increase for the entire cohort.
The most interesting development occurred after the zero-interest-rate era ended. If this growth were purely a side effect of free money, it should have reversed post-rate hikes. Yet in our dataset of 20 funds, the AI-era annual deal count remained nearly flat versus zero-interest-rate levels: 23.9 vs. 24.3. In fact, only three funds slowed their early-stage pace. This proves the shift is structural—though a few outliers inflate the aggregate numbers:
- a16z: 16.6 → 49.7 → 76.8 deals/year
- General Catalyst: 15.2 → 33.0 → 62.1 deals/year
- Khosla Ventures: 14.6 → 21.0 → 30.9 deals/year
At least three fundamental drivers lie behind this:
AI-era companies are inherently costlier. GPU infrastructure, data pipelines, and research scientists commanding $300K–$500K salaries create a completely different baseline cost structure. What cost $500K in the SaaS era (two engineers + AWS) now costs $2M–$5M in the AI era. The expanded median check partly reflects real R&D spend—not just valuation inflation. And while early-stage SaaS was fundamentally exploratory (allowing founders to iterate, pivot, and spend years finding PMF), AI’s first-mover window is dramatically shorter. If your model works, you pull ahead fast—and that window closes faster.
Founder competition has shifted pricing power. At the outset of a revolutionary tech cycle, elite talent paired with top-tier founders is priceless. The best AI founders can choose among a16z, Sequoia, and Lightspeed at seed stage—building shareholder tables that help them raise larger follow-on rounds faster. Often, pricing power has shifted from investors to founders: rounds get bigger not because companies objectively need more capital—but because founders can demand and receive it.
Fund-size math tells its own story. The combined AUM of the top five funds in our cohort grew from ~$34B to $249B—roughly 7x over ten years. Meanwhile, their seed deal counts grew only 2–4x. AUM expansion vastly outpaced seed activity—meaning seed checks constitute a smaller share of these funds’ portfolios.
Take a16z: $4B AUM in 2015, now $90B (including its latest $15B fund—the largest single VC fund in history). A $6M seed check represents just 0.01% of $90B AUM. Mathematically, the fund has zero incentive to haggle over every $1M of valuation. Conversely, in an increasingly concentrated market, missing a generational opportunity is catastrophic.
We can therefore state with high confidence: Mega-funds’ AI-era seed surge isn’t speculative behavior from the free-money era—it’s a strategic mission. Massive capital inflows into mega-funds coincided with a new class of companies and talent worthy of争夺 at the earliest stage—both forces jointly driving this shift.
Group Analysis by Growth Trajectory

Caption: Grouping of 20 funds by growth trajectory
During the zero-interest-rate era, all 20 mega-funds in our dataset increased early-stage activity—no exceptions. Post-pandemic Fed rate cuts to near-zero flooded VC pockets with massive LP capital—U.S. VC fundraising hit a staggering $169.5B in 2021.
With huge dry powder in hand, some mega-funds dipped into seed as a test; others actively exited late-stage rounds (then massively inflated) and pivoted downstream.
By the AI era, however, rates stabilized above 5%, and the market became highly bifurcated. Macro-level divergence split funds into three behavioral paths:
Accelerators
Deal volume in the AI era even exceeded zero-interest-rate peaks:
- a16z (75.3 deals/year)
- General Catalyst (61.5 deals/year)
- Khosla Ventures (31.5 deals/year)
These funds didn’t just stay in seed after cheap capital disappeared—they doubled down, aggressively expanding their presence.
Stabilizers
AI-era deal volume slightly below zero-interest-rate peaks—but still far above SaaS-era levels:
- Sequoia (19.6 → 49.3 → 50.6)
- Accel (15.2 → 43.3 → 34.7)
- Lightspeed (11.6 → 41.7 → 32.1)
The zero-interest-rate surge has peaked and receded—but baseline activity has permanently lifted to 2–3x historical levels. There’s no going back.
Disciplined
Steady growth across all three eras:
- Bessemer (9.4 → 23.0 → 20.9)
- Lux (7.2 → 14.3 → 14.7)
- Index Ventures (10.0 → 23.3 → 17.6)
They avoided both the zero-interest-rate surge and the AI explosion—but their baseline has permanently risen. From ~10 deals/year in the SaaS era, they now consistently execute 15–21.
The sole exceptions are three funds: Founders Fund, NEA, and Greylock. Their early-stage activity either declined or stayed flat from SaaS to AI era.
Founders Fund may be the only institution making a philosophical, active choice. Peter Thiel’s contrarian framework—deeply influenced by Girard’s mimetic theory—treats crowded market consensus as a clear signal to seek opportunities elsewhere. So while 17 other mega-funds rushed into seed, Founders Fund went the opposite direction—placing large, concentrated late-stage bets in generational outliers like OpenAI, Databricks, and Anduril.
Greylock remains deeply loyal to the “first check” tradition—but plays a high-concentration game. It avoids assembly-line deal machines, instead focusing on fewer, higher-conviction bets—sometimes even incubating companies directly in its own offices.
NEA’s large, multi-stage mandate makes isolating its seed volatility harder to analyze; lacking hard data, we refrain from speculation.
Core Strategy vs. Side Hustle

Caption: Change in early-stage deals as % of total investments per fund
Absolute numbers alone can’t answer a critical question: For these giants, is seed a side hustle—or a core strategy?
A fund doing 30 seed deals per year—but also 200 Series A–D deals—means seed accounts for just 15%. Conversely, if those 30 seeds come from 60 total deals, seed represents 50%.
15% suggests scouting, pet projects by individual partners, cheap options. 50% signals strategic mission: dedicated teams, institutionalized processes, scaled deployment machinery.
That’s why our third—and arguably most revealing—lens tracks the precise proportion of each mega-fund’s capital deployed into the early ecosystem:
Of the 20 funds, 16 hit record highs in early-stage allocation during the AI era. In the SaaS era, a typical mega-fund directed 20–30% of its deal volume to seed. In the AI era, that baseline soared to 35–50%.
Three cases are especially compelling:
Sequoia: A complete transformation. This is the most dramatic strategic pivot across our entire dataset. In the SaaS era, Sequoia’s early-stage share was under 20%—it was primarily an A/B+ round powerhouse, making occasional tactical seed bets. By the AI era, nearly half its deals were early-stage—a 30-percentage-point jump.
General Catalyst: A V-shaped recovery. GC was already early-leaning in the SaaS era (38%). It dipped to 30% during zero-interest-rate years—chasing growth-stage returns driven by free money, like peers. But the AI era triggered a sharp reversal—jumping to 47%. This is a conscious, aggressive return to early investing—peaking higher than ever before.
a16z: Stable baseline, then AI leap. a16z’s uniqueness lies in perfectly flat early-stage allocation across SaaS and zero-interest-rate eras—at 31.2%. While others chaotically descended into seed during zero-interest-rate years, a16z maintained structural balance. Then came the AI era—leaping to 42.5%.
This breakdown matters because LPs frequently hear a familiar narrative from mega-funds: “We occasionally write a seed check when we encounter an extraordinary founding team.” Data proves this rhetoric is dead.
Sequoia’s seed share stands at 49%, GC at 47%, a16z at 42%. Mega-funds have fully redirected their core engines to seed—and weaponized the shift with dedicated teams, customized internal channels, and proprietary accelerator programs (e.g., a16z Speedrun and Sequoia Arc).
For EMs, this provides crucial—but sobering—context: Your daily competition extends far beyond the neighboring $50M boutique fund. Today, when vying for allocation, your opponent is a $10B–$90B-AUM giant that’s pointed 40–50% of its institutional deal machine squarely at your sector.
To truly understand the mechanics of this pressure, we must overlay one more key metric: check size and round size.
Classic Seed vs. Super Seed

Caption: Median round size for seed deals involving mega-funds vs. overall U.S. seed market median
A core theme we’ve emphasized is the fracturing of the seed stage. The clearest way to see this rift is to compare median round sizes per era against the broader U.S. “Seed Index” (overall market median).
- In the AI era, the median U.S. seed round with a mega-fund on the cap table is $6.2M
- The overall market median is just $1.4M—a 4.4x gap
Mega-funds simply don’t participate in “average” seed rounds—they systematically operate in the top quartile of the market.
More intriguingly, this multiple gap remains stable across all three macro cycles: 4.8x in SaaS, 4.5x in zero-interest-rate, 4.3x in AI. Mega-funds aren’t accelerating inflation relative to the rest of the market—they’ve always existed in a completely different price tier.
Viewed another way, the market’s 75th percentile ($4M) is mega-funds’ entry baseline. Their median round ($6.2M) sits comfortably above the P75 of the entire U.S. seed ecosystem—by definition, these giants are restricted to the top 25% of deals by size.
But things get even more interesting when we layer median and mean together.

Caption: Comparison of median vs. mean per fund—revealing dual-track strategy
The median reflects a fund’s “typical” deal; the mean is heavily skewed by outliers. The gap between them cleanly proxies how “dual-track” a fund’s strategy truly is: Is it aggressively playing both super-seed and classic seed—or operating uniformly within a single price band?
From this lens, the cohort splits cleanly into two groups.
Dual-Track (gap ≥3x)
- Index (median $8.2M, mean $34.3M, 4.2x gap)
- Lux ($6M vs. $31.7M, 5.3x)
- Lightspeed ($6.8M vs. $30.8M, 4.5x)
- Accel ($5M vs. $26M, 5.2x)
- a16z ($6M vs. $21.8M, 3.6x)
- Sequoia ($5M vs. $17.4M, 3.5x)
These funds play at two tables simultaneously: high-volume classic seed rounds ($5M–$8M), plus highly selective super-seeds ($50M–$500M+), which rocket the statistical mean skyward. Those “$100M seed round!” TechCrunch headlines don’t reflect daily reality—their typical deal is actually 4–5x smaller.
Homogeneous (gap <2.5x)
- Greylock ($6.9M vs. $13.3M, 1.9x)
- Founders Fund ($7M vs. $12M, 1.7x)
- CRV ($7.5M vs. $10.8M, 1.4x)
- 8VC ($6.6M vs. $8.7M, 1.3x)
- NEA ($7M vs. $7.4M, 1.1x)
These funds’ medians and means track tightly—no long tail of ultra-large rounds. They deploy consistently within the $5M–$8M band, with no major outliers.
Dual-track funds dominate headlines, creating the illusion that seed has become a $30M+ game. But data refutes this: Even the most dual-track institutions anchor their typical deals firmly in the $5M–$8M range. Super-seeds are merely the distribution’s long tail—not its center.
For EMs, real competitive pressure comes from homogeneous funds—GC, Khosla, Bessemer, Greylock. These institutions execute systematically in the $5M–$8M band, undistracted by super-seeds. Dual-track funds look scarier in headlines—but pose less threat in daily competition. Part of their time is spent in the super-seed market—a space where EMs wouldn’t compete anyway.
The seed market’s fracture has little to do with abstract round inflation. We’re witnessing two entirely independent ecosystems born under the single label “seed round”: super-seed ($20M+) belongs to dual-track platforms; classic seed ($3M–$8M) remains where mega-funds and EMs still collide. The only difference? The number of multi-stage giants crowding this classic zone has doubled.
Who Sets Price—and Who Just Rides Along?

Caption: Comparison of lead participation rate vs. lead deal count per fund
Participation and leadership are fundamentally different.
A fund writing a $500K check in a $6M round is merely a follower—a passenger on the cap table. The fund leading that round sets the valuation, terms, and who gets invited to co-invest. It’s the lead that ultimately determines whether EMs still have room.
So, what proportion of mega-funds’ seed deals are they actually leading?
I grouped these institutions into four types:
Conviction-Lead: High lead rate + high deal volume
- Khosla (60%, 19 lead deals/year)
- Lightspeed (63%, 21 lead deals/year)
- Accel (54%, 20 lead deals/year)
This is the most dangerous group for EMs. Aggressive deployment—and insistence on sitting in the driver’s seat. Lightspeed leads 21 seed rounds annually, at a 63% lead rate—systematically dominating early-stage pricing. If an EM competes for the same company, they’re fighting for the lead slot.
Volume-Lead: High deal volume, medium lead rate
- a16z (51%, 40 lead deals/year)
- General Catalyst (53%, 33 lead deals/year)
- Sequoia (36%, 19 lead deals/year)
These giants dominate absolute lead counts—even with lower percentage lead rates. They lead the best companies in their pipeline; the rest get passive positions. For EMs, this is a double threat: Even if a mega-fund doesn’t lead, its presence on the cap table significantly impacts signaling and follow-on dynamics.
Selective-Lead: High lead rate, low deal volume
- EQT (82%, 7 lead deals/year)
- Craft Ventures (76%, 8 lead deals/year)
- Index Ventures (67%, 12 lead deals/year)
- Founders Fund (61%, 10 lead deals/year)
- Greylock (58%, 6 lead deals/year)
These funds lead the vast majority of their deals—but maintain high discipline and low velocity. Pure conviction-driven: If they write a check, they almost certainly lead the round. Lower threat in aggregate market volume—but near-certain to take the lead in any specific deal they enter.
Network-Lead: Low lead rate
- 8VC (38%, 9 lead deals/year)
- Amplify (39%, 4 lead deals/year)
- Sequoia (36%, 19 lead deals/year)
- Bessemer (44%, 9 lead deals/year)
These institutions follow far more often than they lead. Their seed-stage role revolves around network, signaling, and option-buying—not setting market pricing. Least threatening to EMs, as they rarely displace lead slots.
An interesting finding: The two funds with the highest absolute early-stage volume have the lowest AI-era lead rates: a16z (51%), Sequoia (36%). Both saw lead rates decline from SaaS-era levels (a16z from 67%, Sequoia from 52%).
The explanation is simple: When executing 77 or 51 deals annually, it’s physically impossible to lead every one. Some naturally become scouting bets, followers, or co-led rounds led by others. At this scale, deal volume and lead rate are an explicit tradeoff.
Yet in absolute numbers, they still dominate the battlefield: a16z leads ~40 early deals annually, GC ~33—more than half the funds on our list combined.
Overall, most funds’ lead rates rose in the AI era. 13 of the 20 funds had higher AI-era lead rates than SaaS-era rates:

Caption: Lead rate change from SaaS era to AI era per fund
Mega-funds are leading more often. Take Greylock: In the SaaS era, it led just one in four seed deals; in the AI era, it leads over half. They’ve shifted decisively from passive “invited-only participation” to active “I’ll syndicate this round.”
LPs conducting fund diligence must remember this reality. Of course, EMs love stacking mega-fund logos in pitch decks alongside “co-invested with XXX.” But this dynamic can serve as a key signal defining precisely what type of venture product LPs are actually subscribing to.
If an LP asks: “How many rounds did you lead last year—and how many had another mega-fund as co-lead?” And the answer is “We frequently co-invest with a16z or GC,” that’s not structural advantage—it’s heavy dependence on mega-funds’ deal flow. Not necessarily a bad strategy, but once you factor in larger round sizes, inflated valuations, and diluted ownership targets due to lack of pricing power and lead capability, the underlying fund math changes dramatically.
Conversely, if the answer is “We lead rounds that mega-funds ignore—or we got there long before they noticed”—that’s the EM’s genuine, defensible advantage.
Where the Pressure Is Highest

Caption: Mega-fund early-stage activity by sector
The above analysis of deal dynamics, round inflation, and lead rates describes mega-funds’ overall behavior. But in reality, an EM rarely invests in “seed as a whole”—they invest in specific sectors, and sector selection is often their core edge. So the next logical question is: Where exactly have mega-funds gone?
From this perspective, their footprint is far more concentrated than aggregate stats suggest.
Unsurprisingly, Enterprise AI & Automation and AI Infrastructure & Developer Tools dominate both lead rates and total deal count. Together, they account for 538 companies—42% of the entire dataset’s early activity. All 20 mega-funds are active in both sectors. Three core drivers underpin this:
Market size. Enterprise spending on generative AI surged from $1.7B in 2023 to $37B in 2025—a more than 20x increase in two years. Enterprise AI already commands 6% of the global SaaS market—expanding faster than any software category in history.
Speed. AI-era time dynamics are unprecedented. The SaaS-era growth model was T2D3 (triple, triple, double, double, double); top AI-native companies’ framework is Q2T3 (quadruple, quadruple, triple, triple, triple). For funds, the seed-stage entry window closes faster. Hesitating 12–18 months could mean missing an entire software category.
Performance outliers. Lovable hit $100M ARR in 8 months—then doubled to $200M in just 4 more—outpacing OpenAI, Cursor, and all other software companies in history. By May 2026, Sacra estimates Lovable’s annualized revenue exceeded $500M. Cursor raised $2.3B at a $29.3B valuation. Anthropic’s annualized revenue accelerated from ~$1B at end-2024 to $14B in Feb 2026, $30B in Apr, $47B in May—while raising $65B at a $965B valuation. All these companies either didn’t exist or were completely obscure three years ago.
For EMs investing in AI, this means nearly every mega-fund is hunting in your backyard. Armed with infinite capital, these giants face no round-pricing constraints—they can aggressively lead and maximize ownership targets. New fund managers’ survival depends on deep domain expertise, exclusive access to high-density founder networks, and the ability to bet before founders even have a pitch deck.
One critical detail: The fastest-growing AI companies (“AI supernovas”) average just ~25% gross margins—deliberately sacrificing unit economics to grab market share. More traditional “meteors” average only ~60% gross margin—still well below the classic SaaS benchmark of 70–85%.
This means enterprise AI is currently a revenue-growth-over-profitability sector. Investors are essentially buying future economics—not current margins. Mega-funds’ deep pockets and long horizons let them easily absorb this structural bet. But an EM managing a $25M–$75M tool faces fundamental vulnerability if future unit economics take longer to materialize than market expectations.

Caption: Median vs. mean round size by sector
AI Infrastructure & Developer Tools warrants special attention regarding round structure. The dual-track behavior observed at the fund level is most acute here: Median round $6.8M, mean rockets to $48M—a 7x gap.
This massive delta signals the sector is saturated with $100M+ super-seeds, inflating the statistical mean. It’s precisely the breeding ground for “$50M seed round” headlines—creating a severely distorted impression of typical deals for observers.
By contrast, Commerce & GTM’s gap is just 1.4x; Healthcare 2.0x. The farther from AI’s core, the more homogeneous the round structure.
Two sectors behave disproportionately to their actual size:
Cybersecurity: Only 76 companies—but a 62% lead rate, the highest among all major sectors. Coupled with a $7M median round (one of the highest in our dataset), mega-funds dominate pricing in nearly two-thirds of deals.
Defense & Aerospace: Smaller footprint (34 companies)—but a record-breaking 66% lead rate. However, only 12 of the 20 mega-funds are active—indicating concentrated, high-conviction bets by a few players—not platform-wide systemic pressure.
Some sectors remain relatively uncrowded: Climate & Energy (26 companies, 12 active funds), Logistics (24 companies, 13 active funds), and traditional sectors like PropTech, EdTech, Legal, and HR.
EMs with deep domain expertise in these sectors completely escape platform-level crushing. Their opponents aren’t 20 large platforms—but 8–12 institutions, each pricing 2–3 deals annually. A completely different game.
This is a critical operational insight for LPs: The right due diligence question for EMs must shift to the specific sectors they operate in—because sector choice defines the nature of competition and the type of differentiation required to win.
Is the Mega-Fund Seed Premium Worth It?

Caption: Seed-to-Series B conversion rate: Mega-fund-backed vs. overall market
So far, this entire study has shown only one side of the coin: Mega-funds invading seed, doing more deals, leading more often, operating in EMs’ price bands.
But there’s one question we’ve deferred until now—and it may be the most critical of all: Does this playbook actually work?
Yes, mega-funds write larger checks, participate in rounds 4.4x larger than the market median, allocate 40–50% of their deal activity to early stage, and lead over half of seed deals. But if the survival rate of companies they seed isn’t meaningfully higher than market average, everything we’ve described is just valuation inflation—with no real value creation.
Conversely, if mega-fund-backed seed companies reach Series B at a significantly higher rate, the entire narrative flips. In that scenario, mega-funds aren’t just “taking over seed”—they’re making seed better. LPs should then ask: “Why not concentrate capital in mega-funds covering seed—and double down in later rounds, capturing the full market lifecycle within a single institution?”
To answer this, we calculated a straightforward metric: Among companies that raised seed in a given era, what proportion later reached Series B? Two comparisons: Overall market vs. seed companies with at least one mega-fund on the cap table.
We focused on the SaaS and zero-interest-rate eras (AI-era companies are too young). Results are clear—but nuanced.
- SaaS Era: Of 60,110 seed-funded companies, 9.8% reached Series B. Of the 940 with mega-fund participation, that jumps to 36.7%—3.7x higher.
- Zero-Interest-Rate Era: Same trend: Market 3.9%, mega-fund 16.5%—a widening 4.2x gap.
Mega-funds convert seed to Series B at 3.7–4.2x the market average. More importantly, this gap is widening. Amid the overheated zero-interest-rate environment—where overall conversion collapsed—mega-funds’ quality filtering became even more valuable.
But before drawing conclusions, we must unpack *why* conversion is so high. Several structural drivers—collectively termed the powerful signaling effect:
- Elite Series A deal flow: Top Series A investors actively seek co-investment with institutional, heavyweight seed leaders.
- Internal follow-on capacity: Mega-funds have deep pockets to lead Series A or B rounds for their own seed portfolio companies.
- Brand-driven talent acquisition: Top engineers seeing “Sequoia-backed” or “a16z-backed” labels experience significantly lower hiring friction.
- Media distribution advantage: Greater PR leverage drives more inbound enterprise customer interest.
We must therefore recognize: A large portion of this conversion lift isn’t mega-funds “picking winners”—but mega-funds helping companies *become* winners. For LPs, this is a clear signal: Mega-funds’ seed-stage value-add goes beyond “stock picking”—it’s genuine “platform-as-product.”

Caption: Seed-to-Series B conversion rate: SaaS era vs. zero-interest-rate era per fund
But the coin has another side. When we move beyond aggregate data to examine each institution, an unsettling pattern emerges: Among the 15 funds with sufficient sample size (≥10 seed deals per era), 14 saw conversion rates collapse from SaaS to zero-interest-rate era. Declines ranged 10–25 percentage points:
- Lux: 51% → 19%
- Sequoia: 46% → 14%
- a16z: 42% → 16%
- Index: 45% → 25%
The correlation is direct: Funds that scaled most aggressively in the zero-interest-rate era saw the steepest conversion drops. Sequoia’s deal volume tripled (20 to ~50/year), yet conversion crashed from 46% to 14%. Lightspeed scaled fourfold (12 to 42/year), conversion falling from 31% to 11%.
The sole exception is Greylock—conversion jumped from 29% to 44%. Not by accident: Greylock is the only fund that kept deal volume nearly flat in the zero-interest-rate era (11.0 to 11.3/year). Fewer deals yielded higher hit rates. Deal-volume discipline equals portfolio quality.
This conversion data both validates and complicates our entire narrative.
On one hand, it proves mega-funds genuinely generate real impact at seed. A 3.7x conversion premium is neither random nor a data artifact. Companies seeded with mega-fund backing *do* survive and grow better. For LPs, it’s strong evidence: Brand, network, and platform resources deliver measurable value.
On the other, volume and quality remain in constant tension. Today, in the AI era, mega-funds’ seed deal volume is hitting records. If the zero-interest-rate pattern repeats, conversion will inevitably erode. The only question is how much. Will AI-era platform effects and signaling advantages offset the dilution from rapid scaling?
A definitive answer arrives in 3–5 years. But historical data delivers a sobering warning: Mega-funds have proven they can pick winners at low volume. They have *not* yet proven they can do so at scale.
It’s precisely in this gap—between a proven past and an unproven present—that the real opportunity for EMs who prepare to do *less*, but *better*, resides.
Danger Index

For our closing section, we did something controversial: We built a Danger Index.
This is a data-driven ranking measuring which mega-funds pose real competitive threats to EMs. We anchor it on three pillars:
Deal Volume: Absolute early-stage deal count per year in the AI era. Higher = greater frequency EMs actually bump into them operationally.
Strategic Commitment: Percentage of fund’s total investment activity allocated to early stage. 45% signals core strategy—staffed by dedicated teams and institutionalized processes. 20% signals a side hustle—readily scalable back to later stages.
Price Overlap: Median round size of fund’s participation. This may be the most critical factor. A mega-fund operating in $8M–$10M rounds competes primarily with other multi-stage giants. But one operating in the $4M–$5M band competes *directly* with EMs—precisely the “sweet spot” where $50M–$100M seed funds deploy capital.
Each factor scores 0–10; final Danger Score is the sum—max 30.
Results were unexpected. Four institutions landed in Tier 1 (highest threat): General Catalyst, a16z, Sequoia, and Accel.
- All four execute 37–83 early deals annually, allocate 39–50% of total investment activity to seed, and operate in the $4.4M–$5.4M round band—striking EMs’ territory directly.
- Counterintuitively, GC ranks ahead of a16z despite a16z’s higher absolute deal volume (83 vs. 65). The difference lies in GC’s perfect alignment across all three risk vectors: high velocity, the highest early-stage allocation in this tier (48%), and a $5M median round—landing precisely at the center of EMs’ pricing sweet spot. a16z’s price point is slightly higher ($5.4M median), and early-stage concentration slightly lower (43%). The gap is subtle—but statistically meaningful.
- Sequoia’s third-place ranking was also unexpected. It has the lowest lead rate (36%) among the top five funds—and follows far more than it leads. Yet its median round is just $4.6M—the lowest among large platforms. It’s systematically buying (by mega-fund standards) cheaper rounds.
- Conversely, Index Ventures surprisingly lands in Tier 3—despite maintaining 19 deals/year and a 66% lead rate. Why? An $8.4M median round. Index operates entirely *above* the traditional EM band.
- The same structural logic applies to Founders Fund ($7.8M median) and Greylock ($7M median)—both solidly in Tier 3. They have clear early-stage footprints—but avoid crowding the price ecology where most EMs fight for survival.
The Danger Index isn’t a death sentence for EMs. We view it as a minefield map.
It distills the entire macro study into one actionable, high-stakes question: “Which Tier 1 platforms are hunting *exactly* in your price band and sector?”
If the answer is “GC and a16z—both investing in AI software, both entering rounds of $4M–$6M,” then the EM must clearly articulate to LPs: What *specific* advantage lets you beat two institutions collectively executing 150 seed deals annually in your backyard?
If the answer is “No Tier 1 giants—I lead $2M–$3M climate tech,” that’s a completely different conversation. The Danger Index shows structural pressure in that sector is far lower—deep domain expertise itself becomes a highly defensible advantage.
Key Takeaways
- Mega-funds’ average early-stage deals grew from 10.6/year in the SaaS era to 23.9/year in the AI era. Only 3 of 20 reduced activity. This is structural—not cyclical.
- Seed valuations have sharply diverged. The 90th percentile hit $93.7M in Q1 2026—nearly doubling in four years. The 25th percentile rose only from $18M to $22.7M.
- In the AI era, the median seed round with a mega-fund is $6.2M—vs. $1.4M overall market median—a stable 4.4x gap across all three eras.
- 16 of 20 funds hit record highs in early-stage allocation during the AI era. Typical mega-funds rose from 20–30% in the SaaS era to 35–50% today.
- 13 of 20 funds now lead more seed rounds than in the SaaS era. Greylock rose from 24% to 58%. Passive following is being replaced by structured lead execution.
- 42% of mega-fund early activity concentrates in two sectors: Enterprise AI & Automation and AI Infrastructure & Developer Tools. All 20 funds are active in both.
- Mega-fund-backed seed companies reach Series B at 3.7–4.2x the market rate. But of 15 funds with sufficient sample size, 14 saw conversion rates plunge from SaaS to zero-interest-rate era—the steepest declines hitting the most aggressive scalers.
- Greylock kept deal volume flat in the zero-interest-rate era—the only fund whose conversion rate actually improved. Deal-volume discipline equals portfolio quality.
- The Danger Index places GC, a16z, Sequoia, and Accel in Tier 1—the only four satisfying all three criteria: high velocity, 39–50% early-stage allocation, and median rounds below $5.5M—directly landing in EMs’ pricing sweet spot.
- Traditional sectors like Climate & Energy, Logistics, PropTech, and EdTech remain structurally uncrowded—only 8–13 mega-funds active (vs. 20 in AI), with lead rates far below category averages.
Conclusion
Mega-funds’ invasion of the early market isn’t a temporary anomaly of a tech cycle—it’s a permanent recalibration of venture capital’s underlying operating model.
As multi-stage giants continue absorbing the top quartile of the seed ecosystem with hundreds of billions, trying to beat them at their own high-velocity, deep-pocket game is mathematically futile. But data reveals a critical crack in their seemingly perfect armor—the inescapable tension between scaled deployment volume and portfolio conversion quality.
In the AI era, the EM’s true advantage lies not in building a larger institutional deal machine—or blindly chasing hot categories priced by Tier 1 platforms. It lies in rigorous sector-selection discipline, patient subscription to complex future unit economics often overlooked by mega-funds, and the courage to stay small, hyper-focused, and deeply bound to founders—long before multi-stage platforms even notice they exist.
In an increasingly scale-obsessed VC ecosystem, the EM’s ultimate counter-strategy is mastering the premium of absolute discipline—not matching giants’ deal volume.
