Analysis
Serval, the San Francisco startup building AI agents to automate enterprise IT work, raised $150 million in a Series C at a $3 billion valuation, Fortune reported October 29, 2026. Source
Sequoia led the round — its third consecutive lead check on Serval, after leading the $75 million Series B in December 2025 that first valued the company at $1 billion.
Serval had been valued at $232 million as of August 2025, according to PitchBook data cited by a Reuters report, meaning the Series B itself already represented a roughly 4x markup before this week's Series C tripled it again.
“Sequoia led the round — its third consecutive lead check on Serval, after leading the $75 million Series B in December 2025 that first valued the company at $1 billion.”
What Serval does
Serval builds an AI agent called Catalyst that creates workflow automations for enterprise IT teams, testing them in a sandboxed environment with branching logic, access controls and audit logs before publishing them to a second agent employees use day to day. Founded in 2024 by CEO Jake Stauch and CTO Alex McLeod, who met at the security-camera company Verkada, Serval has grown from about 20 employees in January 2026 to roughly 200 today, with Stauch telling Fortune he expects headcount near 700 by the end of 2027.
The company counts advertising conglomerate WPP among its customers and says two unnamed Fortune 20 companies converted in the past six months; AI labs Perplexity and Together AI have also used Serval's platform to automate internal tasks, according to a December 2025 Reuters report.
How much has Serval raised
Serval has raised $277 million in total, Fortune reports, including three disclosed rounds in just over a year that each roughly tripled the valuation set by the round before it:
- Series A, 2025 — $47M, led by Redpoint Ventures, with First Round Capital, General Catalyst, Box Group and Bessemer Venture Partners participating. Source
- Series B, December 2025 — $75M, led by Sequoia, valuing Serval at $1B.
- Series C, October 2026 — $150M, led by Sequoia, valuing Serval at $3B and bringing total funding to $277M.
Who invested in Serval
Sequoia has now led all three of Serval's rounds. Elad Gil, Evantic, First Round, General Catalyst and Redpoint Ventures all returned for the Series C, and Conviction and Headline joined as new backers, Fortune reported.
Sequoia Capital has backed other AI-native challengers through multiple markups in a single year, and its concentrated, repeat-lead pattern on Serval fits that playbook closely. Serval's tripling valuation lands at a moment our own funding tracker shows AI-adjacent enterprise rounds accelerating across the board.
ITSM market and competitors
Serval is positioning itself directly against ServiceNow, the incumbent Fortune says was worth roughly $150 billion "before this week's earnings."
The global IT service management market was worth $14.85 billion in 2026, growing at a 16.38% compound annual rate toward $31.71 billion by 2031, according to Mordor Intelligence, with ServiceNow holding the strongest overall platform position ahead of BMC, Atlassian, Salesforce and Ivanti. CTO Alex McLeod argued "it's not just enough to give people a coding agent," a swipe at AI tools that automate narrow tasks without owning a company's full IT workflow.
However, the headline multiple obscures a smaller sample size than it suggests: Serval has not disclosed dollar revenue figures, only that annual recurring revenue has doubled every quarter since the Series B, and a $3 billion valuation built on three Fortune 20 conversions over six months assumes those pilots convert into durable, multi-year contracts rather than one-off automation projects. ServiceNow itself is racing to ship its own AI agents, and a legacy vendor with that kind of market cap and existing enterprise relationships is a very different competitor to displace than a startup.
The clearer tell will be whether ProServal, the new services arm Serval is staffing with more than 100 planned "Automation Engineer" hires, becomes a durable moat or a sign that AI-native IT automation still needs a human layer to close enterprise deals. Sequoia's third consecutive lead check in a year reads less like discovery and more like defending an existing stake against dilution at an ever-higher price, a pattern worth pricing into the next round's terms.
