Union Square Ventures raises $900 million and shrinks its partnership for the AI era

TLDR

• Union Square Ventures has raised $900 million in new capital, split between a $500 million early-stage fund and a $400 million opportunity fund for later-stage and follow-on deals, more than triple the $275 million early-stage fund it raised in 2024.¹²
• The firm is simultaneously shrinking its core investing partnership to four: Fred Wilson, Rebecca Kaden, Nick Grossman and Nikhil Raman, joined by new general partner Michael Mignano.¹²
• Four longtime investors, Andy Weissman, Albert Wenger, John Buttrick and Brad Burnham, are moving into roles supporting USV and its existing portfolio companies rather than making new investments.¹
• USV says it will make a similar number of new investments as before, just writing larger checks per deal to match 2026-era round sizes, and is folding its separate energy fund into the main vehicle.¹

Union Square Ventures, the New York early-stage firm co-founded in 2003 by Fred Wilson and Brad Burnham, announced it has closed $900 million across two new funds: a $500 million early-stage vehicle and a $400 million opportunity fund for later-stage and follow-on bets in existing portfolio companies.¹² That is more than triple the $275 million early-stage fund USV raised in 2024, according to Bloomberg Law.² In its own announcement, the firm said the jump in fund size reflects "bigger rounds and higher prices" across the market, as AI tools make it cheaper to build companies while demand concentrates in a smaller number of winners.¹

The capital increase comes with a smaller team, not a larger one. Bloomberg Law reports USV is "whittling down its general partnership to just four investors," and the firm's own post confirms the core investing group going forward is Wilson, Kaden, Grossman and Raman, plus incoming general partner Michael Mignano, the co-founder of podcasting app Anchor.¹² Jared Hecht, who co-founded GroupMe and Fundera, joins as a venture partner, and former Behance co-founder and ex-Adobe chief product officer Scott Belsky becomes a product advisory partner.¹ Four of the firm's longtime investors, Weissman, Wenger, Buttrick and Burnham, are stepping back from new deal-making into roles supporting existing portfolio companies.¹

USV, whose roughly 130-company portfolio over two decades includes Twitter, Etsy, Stripe, Coinbase, Twilio, Cloudflare, Duolingo and Carta, framed the restructuring around a thesis that AI will "obliterate markets, not automate them," directing the new capital toward application-layer startups that reshape entire markets rather than simply speed up existing ones.¹³ The firm also folded its separate energy-focused fund, first raised in 2021, into the main fund, calling energy investing a necessary enabler of its other theses rather than a side bet.¹ Despite the much larger pool of capital, USV said it expects to make a similar number of investments as its prior funds, deploying more money per deal to keep pace with the larger round sizes now common across the industry.¹

Why it matters: one of the oldest brand names in early-stage venture is betting that the AI era rewards fewer, bigger, more concentrated bets over a broad portfolio, a structural shift that puts pressure on other legacy firms to decide whether to scale up their checks or stay small.
