Resolve AI

We’ve raised an additional $40 million in our Series A Extension at a $1.5 billion valuation, led by DST Global and Salesforce Ventures, to launch Resolve AI Labs, focused on building the domain-specific models and agentic systems required to run software in production. Leading the lab is Dhruv Mahajan, who most recently led post-training for large-scale Llama foundation models at Meta. Foundation models alone won’t cut it. Production environments demand purpose-built models, domain-specific post-training, rigorous evaluation, and agentic systems designed for operational accuracy. That’s why we built Resolve AI Labs.

Meet Elijah, Member of Technical Staff here at Resolve AI. He walked through the door and felt it immediately: pressure, passion, and fire. Hear why he picked Resolve, what makes the team different, and the one word he lands on for the culture here. 👇️

You ever get so far in the weeds on-call that you just want to say “shuck it”? On Thursday, May 7 on a SF rooftop, you can. Once again, we’re teaming up with our friends @Baseten to deliver a different kind of developer meetup. This one features the team at Hog Island Oyster Co., a hundred builders, and a whole lot of shuckers. RSVP to join us and learn how to shuck oysters (and eat your work) alongside fellow engineers. If seafood isn’t your thing, we’ll have plenty of other snacks and beverages to enjoy from the rooftop overlooking the Bay. ordnl.link/mFduacu

A long time ago, in a galaxy far, far away, engineers had to suffer through on-call alone. But they don't have to anymore, and to celebrate, we're hosting a private screening for engineering directors, managers, and their teams and counterparts to see Star Wars: Mandalorian & Grogu at Alamo Drafthouse Cinema in SF on Wednesday, May 27. There will be popcorn, there will be candy, and there will be 250 builders with whom the force is strong. RSVP to join us and invite your engineering teams: ordnl.link/KEESix5

Thank you to @TBPN for the thug life glasses 🕶️ It was great coming on the show and speaking with @jordihays and @johncoogan yesterday to talk AI for prod, our recent funding, and Resolve AI Labs! @resolveai

After watching engineers burn out from fixing late-night outages, Resolve AI CEO Spiros Xanthos is developing AI systems to ease the burden of being on call, backed by a new $40 million funding round. forbes.com/sites/sofiachi… (Photo: Resolve AI)

HumanX 2026 was a blast! The big theme? AI has made it faster to ship code. Now everyone's asking who's going to help them actually run it. See how we showed up at @HumanXco and read our full recap below👇️

Last week amid the energy of HumanX, we hosted a different kind of event with our friends at @Baseten: A dinner mystery filled with engineers who prefer their incidents… fictional. Just like an incident, the assembled crew of builders teamed up to gather clues, review facts, test hypotheses, and explore known unknowns to solve the puzzle. Unlike an incident, the room was filled with laughter, fine food, and method actors making sure everyone had a good time. Dinner mystery > downtime mystery.

From idea to $1B Valuation, @spirosx of @resolveai shares the journey behind their $125M raise. Take a look👇 youtube.com/watch?v=jFEm35…

@augmentcode @braintrust @browserbase @mintlify @modal See you at 'Death by Deployment' tonight with @baseten luma.com/lg5o0vvh

A Wednesday evening well spent! Thank you to all the builders who came out to AI After Hours last night. We had a blast hosting you with our friends at the SFMOMA. Be on the lookout for more events like this! @AugmentCode | @Braintrust | @Browserbase | @Mintlify | @Modal | @MongoDB | @StainlessAPI | @WorkOS

Scenes from the show floor. Day 1 at @HumanXCo is nearly a wrap but the best is yet to come. There's still time to grab a custom hoodie, watch @SpirosX's Masterclass on agents for on-call and prod, and kickback with some of your favorite startups at SFMOMA. Details: resolve.ai/events/humanx-…

No decks. No panels. Just drinks, dinner, and figuring out which AI engineer at the table is a traitor. We teamed up with @Baseten for a murder mystery builder meetup. Thursday, April 9 at 5:30 pm. luma.com/lg5o0vvh

This just in: @harmonic_ai’s Hot 25 just dropped. And we’re excited about the list. Congrats to everyone at Lightspeed portfolio companies @resolveai, @dualentry, @paid_ai, and @_StacksAI for ranking among other top early-stage companies based on investor interest. Hard work pays off, and we can’t wait to see what’s next for their teams!

Meet Kshitij, Member of Technical Staff at Resolve AI. He joined looking for three things: the smartest people, a problem worth solving, and real ownership. He found all three. Hear why he thinks the safety net is a trap and what building at Resolve AI actually looks like from the inside.

We put Nick Jonas on-call. No, not that one. Our frontend engineer. The catch? He had never been on-call before. We gave him Resolve, a hug, and a couple of well wishes before we sent him off as our on-call engineer for the week. Learn what it was like for Nick to be on-call for the first time, and how using Resolve impacted his experience 👇️ resolve.ai/blog/we-put-ni…
