Benchmark Breaks 20-Year Tradition with $2 Billion Raise and First Growth Fund Targeting AI Agent Startups

Benchmark Capital has raised $2 billion across two new funds, including a $1.25 billion growth vehicle dedicated to later-stage investments. The raise breaks Benchmark’s signature two-decade discipline of capping funds at roughly $425 million, according to TechCrunch, citing the Wall Street Journal.

The remaining $750 million goes to a new early-stage fund. The growth fund will make five to six large investments in both existing portfolio companies and new startups, TechCrunch reported.

What Triggered the Shift

Benchmark’s Cerebras bet provided the catalyst. The firm first led the chipmaker’s Series A in 2016, then raised a $225 million special purpose vehicle (SPV) to participate in a $1 billion pre-IPO round. Cerebras held its IPO last month, returning Benchmark $3.25 billion at the IPO price, per TechCrunch. That windfall prompted the dedicated growth fund.

The firm’s relatively small fund sizes had locked it out of capital-intensive AI model companies. Benchmark holds no position in Anthropic, OpenAI, Periodic Labs, Reflection AI, or Recursive Superintelligence, all of which command round sizes in the hundreds of millions, according to TechCrunch.

Agent Infrastructure Bets

Where Benchmark has placed AI bets, the focus has been agentic infrastructure rather than foundation models. In recent months the firm backed two Series B startups: Gumloop, a platform that lets enterprises create AI agents without writing code, and Monaco, an AI-native sales and CRM platform, per TechCrunch.

Not every agent bet has paid off. Benchmark led a $75 million round in Manus, a Singapore-based AI agent platform that hit $100 million ARR within eight months of launching. Meta agreed to acquire Manus for roughly $2 billion late last year, but Chinese regulators blocked the deal in April, arguing the company violated export control laws. Benchmark’s Manus stake remains in limbo.

New Partners, New Playbook

Benchmark has also reshuffled its general partner roster. Miles Grimshaw left for Thrive Capital in 2024. Sarah Tavel, the firm’s first and only female general partner, moved to a venture partner role last year. Victor Lazarte departed to start his own firm. To fill the gaps, Benchmark added Everett Randle from Kleiner Perkins and Jack Altman, brother of OpenAI CEO Sam Altman, per TechCrunch.

Randle previously told TechCrunch that the firm looks to build “meaningful and deep relationship with the entrepreneurs, and that can happen relatively early in the company’s lifecycle, at seed, A, at B.”

What the Growth Fund Signals

Benchmark’s thesis is clear in its portfolio: the next investable layer in AI is not the models themselves but the infrastructure that lets agents do useful work inside enterprises. Gumloop (no-code agent building), Monaco (AI-native CRM), and the blocked Manus deal (general-purpose agent platform) all sit in that stack.

The $1.25 billion growth fund gives Benchmark the capital to follow those bets through later rounds, where AI infrastructure valuations have ballooned beyond what a $425 million vehicle could support. For agent infrastructure founders, the signal is straightforward: one of Silicon Valley’s most disciplined early-stage firms now has growth capital to deploy, and it’s pointed at their category.
