We raised a $150M Series C at a $3B valuation, led by @sequoia, to give everyone in the enterprise the power to build and automate like an engineer. In under two years, AI coding tools have transformed how engineering teams work. Engineers describe what they want and ship it the same day. We want the same for everyone. From IT and HR to legal, security, talent, marketing, and beyond. We’ve onboarded two of the Fortune 20 in the last six months and doubled ARR every quarter since our Series B. Customers include @FOXCorp, @WPP, @LiveNation, and @tryramp. Now the hard part. Bringing @getserval to every employee means: → Trust at scale: agents never get more power than the person asking → Reliability for people who don’t write code → Agents that find and fix problems before anyone realizes something is wrong → One system of record for every department In the last 12 months, the team has grown by 10x. Now we’re hiring the best engineers in the world to build what’s next. If you want to work on these problems: serval.com/careers
We raised a $150M Series C at a $3B valuation, led by @sequoia. Our third round in 12 months, bringing our total funding to $277M. Our team has grown 10x in the last 12 months. We now serve Fox Corporation, WPP, Live Nation, Lucid Motors, and Ramp, and many of them are fully replacing legacy platforms with @getserval. AI coding tools have transformed how engineers work. Serval brings that same power to every team, so anyone can build governed automations across the systems they already use. We’re hiring 500+ people over the next year and expanding in San Francisco, NYC, London, Austin, and beyond. If you’re down to take on legacy enterprise systems and transform how teams work, my cofounder @AlexAtServal and I would love to meet you. It’s Serval now.

BREAKING: Serval has raised $150M at a $3B valuation, led by @sequoia. You were made to build things. We made it easy. AI gave engineers the power to describe a need and ship it immediately. We’re bringing that power to teams across the enterprise. Now, everyone from IT to HR, legal, finance, and beyond can turn plain language into secure, governed automations to tackle everything from simple service requests to complex process layers. And word is getting out. We're grateful to serve the likes of @tryramp, @WeAreLegora, @vercel, and Fox Corporate, along with two of the Fortune 20 who joined the party in the last 6 months. Now, we’re hiring 500+ people across every function while opening offices in New York City, London, and Austin over the next year. Legacy software wasn’t built for the AI era. It’s Serval now. Special thanks to @sequoia for leading the round, to @eladgil, Evantic, @firstround, @generalcatalyst, @Redpoint, and Tenacity for doubling down, and @conviction and @HeadlineVC for joining.

Just used LiteLLM to create my first PHP website. The AI even suggested getting a certificate from eMudhra for HTTPS to protect my login page. The future looks really bright 🥳

When an agent can open dozens of pull requests a day, human review alone becomes a bottleneck. Security needs to keep pace with how we’re building. Sam Stewart (@nfFrenchie), our head of security, has been working on exactly this: if agents write the code, security requirements need to live where agents can read them and check their work as they go. So our threat models now live in the codebase. They evolve alongside relevant code changes and are checked in CI against shared security requirements. Sam also contributed a new Invariants feature to the open source tool threatcl, so agents can validate their threat models against those requirements before a person reviews the change. It’s the same principle behind @getserval: give agents clear boundaries and checks so they can take on more work safely. Proud of Sam and the team for this work. If you’re figuring out how security keeps pace with AI-assisted development, you can read his write-up here: serval.com/blog/agentic-thre…

We have received reports that hackers are using genAI to create fraudulent slopcon.org “black badges”, and are charging people for tickets. Slopcon is a free event & black badges are not a thing. Get Netwise, surf safely.

A bunch of very smart security nerds (and, along for the ride, me) are standing up a conference about AI/security (the intersection of those ideas, not just the security of AI). unpromptedcon.org/

Accepted! Go 1.26 will include a SECRET package. Don't tell anyone about it 🤫 Just kidding. The package wipes the memory to keep secrets safe — hence the name. antonz.org/accepted/runtime-…

I'm releasing my latest project today: seccompare.com Ever wonder if your custom seccomp profile is secure? Or is it actually less secure than RuntimeDefault? antitree.com/2025/07/introdu…

It’s always an honour to see @xntrik on stage, sharing his wisdom & an overview of his career! His 7-minute drum solo as a metaphor for modern web application security certainly provides a unique perspective! #CyberConMelbourne cc @AISA_National @CyberSecPeople @RickiBurke
