# US Venture Capital Firms Backing Cybersecurity, by Stage (304 Firms, 2026)

TL;DR
- Qubit’s research identifies 309 US venture capital firms on the [SEC](https://www.sec.gov/data-research/sec-markets-data/information-about-registered-investment-advisers-exempt-reporting-advisers) roster backing cybersecurity. This page covers the 304 with a documented stage.
- By stage: Pre-seed 151, Seed 223, Early stage (Series A–B) 200, Growth and later 157.
- Stage and sector are drawn from Qubit’s investor research. A firm with no documented stage is omitted, not guessed at.

Rank cybersecurity by assets and Sequoia Capital leads with $82.2 billion. A founder raising seed should ignore that ordering.

These firms also back Enterprise SaaS, AI and Cloud Infrastructure. Seattle is home to 1.94 times its usual share of them. 1 keep to three sectors or fewer rather than spreading wide.

As a share of all documented US firms, that comes to 19.6 percent. Stage overlap is common here, with 240 of the 304 funding several.

## Where these firms came from

The roster is [SEC Form ADV filings](https://www.sec.gov/data-research/sec-markets-data/information-about-registered-investment-advisers-exempt-reporting-advisers), dated 1 July 2026, and it supplies all 309 firms. The roster mix is 253 exempt reporting advisers against 56 registered advisers.

Several SEC registrations belong to 25 cybersecurity venture capital firms, each listed once. 71 of them file under one name and trade under another, so both are listed. Filed assets are self-reported once a year, so they lag.

A dash means we could not document that firm’s stage or sector.

## Pre-seed: 151 firms

These 151 write first cheques, usually before there is revenue. The largest are General Catalyst, Accel Management, Kleiner Perkins and Bessemer Venture Partners.

## Seed: 223 firms

These 223 firms take part in seed rounds. The largest are Adams Street Partners, Ribbit Capital, Battery Management and 8VC.

## Early stage (Series A–B): 200 firms

200 of them invest at Series A and Series B rounds. The largest are Greylock Partners, Notable Capital Management, Sapphire Ventures and Felicis Ventures.

## Growth and later: 157 firms

These 157 put money into companies that are already scaling. 47 of them back Big Data. The largest are Alkeon Capital Management, K1 Investment Management and DFJ Growth.

## All 304 firms

All 304 cybersecurity firms are listed above, and most are wrong for you. Only 149 of them also back Enterprise SaaS, and fewer still at your stage. Qubit’s [investor mapping](/startup-services/investor-mapping) narrows it to the firms that fit your round.
