October 2026's Most Active Lead Investors: Andreessen Horowitz Led 11 Tracked Rounds

Andreessen Horowitz led 11 of the 306 US startup funding rounds Value Add VC tracked in October 2026, as of November 7, 2026 — more tracked rounds led than any other firm that month.

These are lead-investor counts across rounds tracked by Value Add VC for US and unconfirmed-HQ private companies, as of November 7, 2026; rumored rounds, public-company raises, and known non-US companies are excluded. This is not a claim about every round that closed in October — it's a slice of the market from the sources Value Add VC follows, meant to be compared month to month within this series. Below are the 12 most active lead investors, ranked by tracked rounds led.

Most Active VC Firms October 2026: The Full Ranking

Tracked as of November 7, 2026, Andreessen Horowitz led the most tracked rounds (11) and touched the most total deals (22, combining led and joined). General Catalyst ranks second on both counts, co-leading three of October's largest tracked rounds. Sequoia Capital joined more deals than it led, touching 13 total.

Computed from the Value Add VC intelligence store on 2026-11-07: lead-investor counts from funding rounds of US and unconfirmed-HQ private companies announced in October 2026; rumored rounds, public-company raises, and known non-US companies excluded; one record per deal. Not a market total; each top round links its own source. How we counted: lead and participating-investor tags on rounds Value Add VC's intelligence store had on file for October 2026; ranked by tracked rounds led; 12 firms in 2+ tracked rounds; as of November 7, 2026.

Which VC Firm Led the Most Startup Funding Rounds in October 2026?

Andreessen Horowitz led 11 of the 306 tracked rounds, the most of any single firm. Its largest tracked round was TypeSafe AI's $870 million Series A at a $7.5 billion valuation, with Sequoia Capital, DCVC, and angel investors participating alongside it.

General Catalyst led 9 tracked rounds, the second most, and appears on three of October's biggest deals: Axiom Solutions' $2 billion convertible-preferred investment at a $37.5 billion enterprise value, co-led with Koch Equity Development; Re:Build's $2.1 billion raise, co-led with JPMorganChase's Strategic Investment Group; and Oratomic's $475 million Series B, a six-way co-lead with ARCH Venture Partners, Spark Capital, Khosla Ventures, Index Ventures, and Bezos Expeditions.

Which VC Firms Were Most Active by Total Deal Count in October 2026?

By total tracked deals — leading plus participating — Andreessen Horowitz tops the list at 22 as of November 7, 2026, more than any other firm that touched a tracked round in October. It led 11 and joined 11 more, spreading activity across roughly twice as many deals as the next firm.

General Catalyst was next with 15 total tracked deals (9 led, 6 joined), followed by Sequoia Capital at 13 (5 led, 8 joined) — the widest gap between leading and participating of any firm in the top five, suggesting Sequoia spread October capital more through follow-on and syndicate positions than new leads.

Why Did Quantum Computing and AI Infrastructure Draw So Many Repeat Leads?

Oratomic's $475 million neutral-atom quantum computing round pulled in six co-leads at once — General Catalyst, Khosla Ventures, and Index Ventures all count it among their October tracked rounds, which is why three different firms in this ranking cite the same deal as a top round. That kind of crowded syndicate is typical of a hot, capital-intensive category where no single fund wants to miss a round but no one wants to write the whole check alone: Oratomic's valuation reportedly jumped from $1.5 billion to $5.5 billion in the same financing, according to SiliconANGLE.

Accel's solo lead on Modal Labs' $750 million Series D, which tripled Modal's valuation to $15.75 billion in five months, is the opposite pattern — one firm taking outsized conviction in AI cloud infrastructure rather than splitting the round. Index Ventures and Lux Capital showed a middle path, co-leading Flapping Airplanes' $1 billion Series A at roughly a $6 billion valuation, a round that also drew Sequoia, GV, Kleiner Perkins, and Nvidia as participants.

What the headline misses

Lead-investor counts reward firms that write a lot of checks, not necessarily the firms that write the biggest or sole ones. Andreessen Horowitz tops this list on rounds led, but, as of November 7, 2026, four of General Catalyst's and Khosla Ventures' tracked rounds this month were part of the same multi-firm co-leads (Re:Build, Axiom Solutions, and Oratomic), meaning several firms in the top eight are partly counting the same deals. And several firms lower in the ranking (Lightspeed Venture Partners, Bessemer Venture Partners) led or joined deals the pack didn't flag as "top rounds," meaning Value Add VC's own store carries less individual-deal detail on those than it does on the month's largest tracked rounds. Treat this as a count of tracked activity, not a ranking of investment quality or returns.

How We Built This List

This ranking counts lead and participating-investor tags on US and unconfirmed-HQ-private-company funding rounds in the Value Add VC intelligence store that were announced in October 2026, with one record kept per deal. It excludes rumored rounds, public-company capital raises, and companies with a confirmed non-US headquarters. The store tracked 306 such rounds worth $38.9 billion combined as of November 7, 2026 — a slice of the market from the sources Value Add VC follows, not a claim to cover every investor active that month.

Lead-investor counts come from the store's own records; the "top tracked rounds" shown for each investor are limited to the deals with the highest tracked dollar value that month, and each one is checked against its own linked source — TypeSafe AI's figures against its own blog post, Re:Build's against TechCrunch, Axiom Solutions' against Pulse 2.0, Oratomic's and Modal Labs' against SiliconANGLE, and Flapping Airplanes' against TechCrunch.

The full round-level log this list draws from is public at Value Add VC's funding tracker, and the rounds themselves are ranked separately, as of November 7, 2026, in October 2026's biggest US startup funding rounds and, across the full year to date, in 2026's biggest US startup funding rounds so far.
