Jake Stauch has a theory about the prison yard: on your first day, find the biggest guy and beat him up. "It was just a fight that we decided to pick," the Serval co-founder and CEO told Fortune. The biggest guy is ServiceNow, and Serval's pitch is built around replacing it.

That fight now has a price. Serval raised $150 million at a $3 billion post-money valuation, its third round in twelve months and its second led by Sequoia, which also led the $75 million Series B in December at a $1 billion valuation. Total funding is $277 million. Elad Gil, Evantic, First Round, General Catalyst and Redpoint returned; Conviction and Headline joined.

The company had about 20 employees in January and has roughly 200 now. Stauch expects at least 700 by the end of next year.

The thesis is narrow and testable: ServiceNow, under the branding, is a workflow-automation company built on drag-and-drop tools and custom configuration. If AI writes code well enough, that configuration work becomes cheap, and so does the moat around it. "If workflow automation is about to be disrupted," Stauch said, "then actually what we're building is not just a solution for these customers we've been talking to, but it's actually a new generation of massive enterprise software company."

The product is two agents. Catalyst builds automations, tests them in a separate environment with branching, access controls and audit logs, then publishes them to a second agent that employees use for things like access requests, technical support and asset tracking. Serval says annual recurring revenue has doubled every quarter since the Series B. It will not give dollar figures. It names WPP as a customer and says two Fortune 20 companies converted in the last six months — names it cannot disclose.

ServiceNow's answer is both an argument and a product. Sean Regan, general manager of Flow by ServiceNow, told Fortune: "Anyone can build a great demo. Running mission-critical operations for a global enterprise, securely and with every AI action governed, is the hard part." Flow launched on 1 October as a standalone AI service desk that can be running in a day, sold at a published $2 per conversation, buyable with a credit card by companies with no ServiceNow contract.

The incumbent's numbers are awkward for both sides. Third-quarter revenue of $4.11 billion beat estimates; earnings of $1 a share missed the $1.02 consensus, and fourth-quarter guidance of $4.25–4.26 billion came in below the $4.36 billion analysts expected. The stock fell more than 17% after hours on Wednesday and more than 26% on Thursday. At the same time ServiceNow says agentic AI consumption in production is up more than 13 times year over year, renewal stands at 98%, AI ITSM deal volume is up nearly 80%, and it raised its 2026 AI annual-contract-value target to $1.7 billion from $1.5 billion.

So the market punished the incumbent for forward guidance while the incumbent reports AI demand accelerating. Serval's round is a bet that the second number is a lagging indicator.

Serval is also hiring into the argument. It is launching a services arm, ProServal, and plans to add more than 100 "automation engineers" over the next year — about half straight out of college, four weeks of training, then embedded with customers to rebuild workflows. The company cites a Stanford Digital Economy Lab finding that employment for 22- to 25-year-olds in the most AI-exposed jobs has fallen 13% relative to older workers since late 2022, and argues the answer is more people doing the rebuilding, not fewer.

What is not yet proven is the part the valuation now depends on: that a 200-person company can hold a system of record for global enterprises. Serval discloses no revenue, no churn and no contract sizes. Sequoia partner Anas Biad calls it "on a trajectory to be the fastest-growing top-down Enterprise system-of-record company in history" — a claim only the next four quarters can settle.
