Key Takeaways

  • Mega-funds operate under an IPO-or-bust mandate because returning multi-billion-dollar pools demands rare $30B to $50B public market exits.
  • Venture funds managing under $1B in assets have structural flexibility to target mid-tier M&A transactions between $100M and $1B.
  • Writing checks at entry valuations below $100M allows smaller funds to return capital through realistic corporate acquisitions rather than waiting on frozen public listings.
  • SC Moatti argues that the power-law doctrine is a self-imposed restriction forced onto mega-funds by their asset base, not a universal law of early-stage investing.

The Mega-Fund Constraint vs. Mid-Market Flexibility

Venture capital orthodoxy states that funds must capture extreme power-law outliers to generate top-decile returns. On How I Invest, host David Weisburd asked SC Moatti, Managing Partner at Mighty Capital, why she rejects this consensus.

Moatti is direct: power-law dependency is not a virtue. It is a restriction created by excessive fund size. “I disagree because I think it's a strategy that you have to adopt if you have no other choice,” Moatti explained. “So who has to do that are the mega funds.”

When a firm manages several billion dollars, small outcomes fail to move the needle. A $500M acquisition produces negligible DPI for a $3B vehicle. Mega-funds require companies to scale into public market candidates worth $30B to $50B. The math forces them into an all-or-nothing posture where every portfolio company must attempt to conquer an entire category or die trying.

For managers operating sub-billion-dollar funds, the return mechanics look entirely different. “If your fund is say less than a billion AUM, then you actually have more options,” Moatti said. “You can divide your fund size into tickets that fit into a strategy that generates M&A as an option.”

The Real Liquidity Band: $100M to $1B M&A

The public IPO market opens and closes in multi-year cycles. Enterprise M&A, by contrast, operates continuously across economic conditions. Strategic acquirers regularly buy established product engines, specialized engineering teams, and customer cohorts without needing board approval for multi-billion-dollar mega-deals.

“Most M&A happen in the hundred million to $1 billion range,” Moatti noted. “But if you have a fund that allows for tickets that go into a company that's sub-$100 million in valuation, as long as it exits in that 1 billion range, you still make a lot of money for your investors.”

A $40M entry valuation exiting in an acquisition for $400M yields a 10x gross return on invested capital. For a $150M or $300M fund, a few transactions in that window return the entire vehicle with meaningful profit. Chasing only the top 0.1% outcome forces founders into aggressive dilution, unsustainable burn rates, and premature market expansion.

“The power law strategy is a strategy that works, but it's one that's so restrictive that you really only want to adopt it if you don't have another choice,” Moatti stated. Structuring investments around capital efficiency gives sub-billion funds multiple paths to liquidity, protecting LPs from the binary risk profile of mega-fund portfolios.

Why It Matters

This dynamic exposes a growing divergence between fund size and capital efficiency across private markets. As public listing requirements stiffen, mega-funds face mounting pressure on DPI because their paper valuations cannot clear the $30B public market liquidity bar. Sub-billion managers who maintain entry valuation discipline under $100M can access consistent M&A liquidity in the mid-market, returning cash to LPs years faster than mega-cap venture peers trapped in paper markups.
