General Catalyst Led $5.1 Billion in Startup Rounds in October

General Catalyst led or co-led venture rounds collectively valued at $5.1 billion in October, making it the busiest U.S. startup dealmaker of the month by both round count and deal size, according to Crunchbase rankings.

The firm, known for investing across stages and sectors, led at least nine known rounds. Lightspeed Venture Partners came next with eight lead rounds. Sequoia Capital and Andreessen Horowitz each led seven deals.

The rankings covered three measures: lead deal count, largest lead investments and total venture rounds.

Which investors spent the most?

General Catalyst's $5.1 billion total owed much to two outsized financings. The largest was a $2.1 billion round for Re:Build, a startup that partners with manufacturers for product design and production. The second was a $2 billion Series A for Axiom Solutions International, a cloud and power infrastructure spin-out of manufacturing provider Flex.

A $2 billion Series A is an unusual structure. Most companies at that stage raise a fraction of the amount. The size reflects Axiom's origin inside an established manufacturer rather than a typical early-stage startup.

J.P. Morgan Asset Management, which co-led the Re:Build financing, ranked as the next heaviest spender. Koch Equity, which co-led the Axiom deal, followed. Next came the five co-lead investors in Ramp's $1.9 billion Series G. Ramp is a fintech unicorn, and its round alone placed its five co-leads among the month's top spenders.

Who did the most deals overall?

The ranking of most active venture investors by round count repeated many of the same names, with some switch-ups. Y Combinator took its customary spot as the busiest investor by round count in deals of $5 million or more. The famed accelerator typically participates as a nonlead backer in follow-on rounds for startups that went through its program.

Andreessen Horowitz ranked second, participating in at least 22 qualifying rounds. General Catalyst followed with 17.

The tallies draw only on known rounds. Lead counts and participation counts can shift as companies disclose financings after the fact, a common lag in venture data.

Is startup funding slowing down?

By Crunchbase's reading, no. Active investor rankings across all three metrics point to an upbeat startup funding environment.

October produced no round close to the record-setting megafinancings for OpenAI and Anthropic earlier this year. Even so, the analysis finds venture investors still willingly writing big checks, and plenty of them.

That matters for founders planning raises into year-end. When the top of the lead-investor table concentrates billions in a single month across software, manufacturing and fintech, the money remains available for companies that can command scale.

The breadth is as telling as the size. General Catalyst, Sequoia, Andreessen Horowitz, Accel and Lightspeed each ranked high across multiple measures, meaning October's volume did not rest on one firm or one sector. The month's largest checks went to manufacturing-adjacent builders — Re:Build and Axiom — rather than to a single model developer, and fintech's Ramp supplied the third billion-dollar-plus round on the list. If November repeats the pattern, 2025's late-stage funding pace will end the year closer to its peak than to the trough.
