How should LPs think about VC fund size?
Description
What does fund size mean in venture today?
A few weeks ago, I shared some thoughts on Twitter and LinkedIn about the evolution of venture capital and how LPs should think about deploying capital in today's market. The venture capital landscape has fundamentally changed, and it's time our frameworks caught up.
Twenty years ago, venture capital was relatively uniform. Most firms followed similar strategies, wrote similar check sizes, and built portfolios in roughly the same way. This uniformity made sense—technology was still early in transforming the world, and the annual venture capital deployed was a fraction of what it is today.
But the industry has transformed dramatically. The rise of institutional seed funds, the emergence of mega-platforms, and the sheer scale of the industry have turned venture capital into a collection of distinct strategies. Yet many LPs still use a monolithic lens to assess venture capital, which results in the ongoing comparison of "large vs. small" VC funds, which misses the point—these aren't just different fund sizes; they're fundamentally different economic products with unique risk-return profiles and business models.
Each can have a place in an LP portfolio, dependent on risk/return tolerance, capital base, time, access, etc.
To analyze these segments effectively, we can categorize venture funds into distinct size tiers that reflect their different business models:
Small-Cap Funds (<$250MM):
These funds represent most closely the traditional venture model, with their sizes lending toward focusing on seed and early Series A (primarily follow-ons) investments.
Mid-Cap Funds ($250MM-$1B):
Since this is a fairly broad range, I wanted to segment it further by type for this analysis.
Smaller-Mid Cap ($250MM-$499MM): These funds often maintain significant early-stage exposure while gaining the ability to participate meaningfully in follow-on rounds (exposure is generally seed-Series B).
Larger-Mid Cap ($500MM-$999MM): At this scale, funds begin showing characteristics of large-cap funds. In this category there have emerged high quality specialist brands (fintech, enterprise, consumer, deep-tech).
Large-Cap Funds ($1B+): These funds typically can be raised only by strong brands, and the fund size lends to investing across the stage spectrum, and seed investing is normally for optionality. Initial core checks are typically done at the A or B rounds, with exposure often going through Series C/D.
To understand how fund size shapes strategy and returns, I analyzed historical fund performance data from PitchBook across two distinct market cycles: 2000-2010 (post-bubble through financial crisis) and 2010-2020 (post-GFC and ZIRP period). The analysis used simple weighted averages for returns.
*It's important to caveat that returns for funds later in the 2010-2020 cohort may still be too early to entirely rely on.
Small-Cap Funds (<$250MM):
The data shows small-cap funds maintain the closest resemblance to traditional venture investing. The return profile demonstrates the potential for significant outperformance and increased downside risk.
Typical Characteristics:
Portfolio Construction: Typically 25-35 companies, though some managers pursue broader portfolios of 50-100+ companies at pre-seed/seed stages, given limited visibility on eventual winners
Stage Focus: Heavy concentration in Seed- Series A, often deploying 50-100% of capital at seed.
Investment Approach: More likely to pursue non-consensus investments or focus on specialized sectors
Mid-Cap Funds ($250MM-$1B):
Smaller-Mid Cap ($250MM-$499MM):
Typical Characteristics:
Initial core checks at Series Seed and A
Critical focus on ownership
Will follow on in a select group of companies through Series B
25-35 Companies
Larger-Mid Cap ($500MM-$999MM):
Typical Characteristics:
Initial core checks at Series A and Series B
Critical focus on ownership (15-20% minimum for initial check)
Will follow-on in a select group of companies through multiple rounds, often to Series C.
25-35 Companies
Large-Cap Funds ($1B+):
Typical Characteristics:
Full lifecycle investing from Seed to late-stage growth
Critical focus on ownership concentration
Can invest in consensus and be relatively price-insensitive on initial checks to win "best" deals (hot sectors, companies with momentum, or tangibly strong teams/founders)
Brand and reputation as prerequisites
A limited number of firms can operate effectively at this scale.
The Assessment of Fund Size in Portfolio Construction
Small Cap Venture:
Highest return potential with corresponding volatility.
Manager selection is crucial given the wide outcome dispersion.
Best suited for maximum return-seeking portfolios (if manager selection can be done consistently well).
Mid-Cap Funds:
Balanced risk-return profiles.
Progressive compression of returns with scale.
Improved downside protection from small cap, but higher return potential than large-cap.
Large-Cap Platforms:
Most consistent return patterns, with reduced upside/downside.
Strongest downside protection.
Ideal for reliable, scaled venture exposure.
Rethinking Venture Capital Allocation
The evolution of venture capital mirrors that of other private market segments. Just as institutional investors wouldn't compare a large buyout fund to a small-cap niche specialist in private equity, we need to move beyond simplistic "large versus small" comparisons in venture capital.
The data shows that each segment can serve a distinct
