Today we're announcing Runta's $20M seed, led by a16z. Software is constrained when you write it. Agents have to be constrained while they run. Runta is the execution layer that controls what AI agents can actually do.

@runta @a16z Congrats Guanlan! Very excited for you!

@runta @a16z @drfeifei Thank you so much for your support from the very beginning, and especially for encouraging us to look for true intellectual partners in our earliest hires.

The next billion new computer users won't be humans. They'll be agents. An agent's behavior is decided at runtime, by whatever lands in its context. You can't review what you can't see in advance. The control point has to move to execution. We raised this round to build the execution layer for them:

Thank you @martin_casado for leading this round, and @JeffDean, @drfeifei, @alighodsi, @Thom_Wolf, and Ram Shriram for backing us this early.

@JeffDean @drfeifei @alighodsi @Thom_Wolf We're onboarding early teams now. If your agents are ready for real work, apply for access:

@JeffDean @drfeifei @alighodsi @Thom_Wolf Thank you @steph_palazzolo for the great exclusive on @runta in @theinformation.

@JeffDean @drfeifei @alighodsi @Thom_Wolf @steph_palazzolo @runta @theinformation And we're hiring. Come build the execution layer for the next billion agents.

@JeffDean @drfeifei @alighodsi @Thom_Wolf @steph_palazzolo @runta @theinformation Thrilled to be partner with @martin_casado. Few people have thought harder about what happens when the infrastructure layer shifts.

@runta @a16z Congratulations @guanlan, looking forward to collaborate on the Inference Layer!

@runta @a16z Ty @simon_mo_ , would love to collab!

@runta @a16z Huge congrats! @guanlan my role model as an infra founder🔥

@runta @a16z Thank you Johnna for the support!

@runta @a16z congrats @guanlan ! Execution layer is very hard to build, but extremely important primitive for the world with agents in the next 5 years

@runta @a16z Totally agreed. For enterprises and startups, this is the gating factor to moving agents from read-only experiments into real production work.

@runta @a16z This is basically critical infra for agents

@runta @a16z Before agents can run production, they need to learn how to walk safely.

@runta @a16z Congrats on the launch. Really excited to see where you take this.

@runta @a16z Big fan of what @TigrisData is doing on agent storage, we're working on the execution layer at @runta , and these two problems clearly meet in the middle. Would love to find ways to collaborate.

@runta @a16z @TigrisData Love it.

@runta @a16z congrats!!

@runta @a16z Congratulations!

@runta @a16z congrats, Guanlan! where to apply for early access? please sign me up and take my money

@runta @a16z Awesome, sign up here!

@runta @a16z Congrats Guanlan!

@runta @a16z you rock @guanlan! congrats

@runta @a16z Thank you @MichelleLazzar for the amazing media support behind the scenes.

@runta @a16z Congrats!

@runta @a16z Finally get to share what we’ve been building: the execution layer that lets AI agents take real-world actions without giving them unlimited access. So proud of this team 🦊

@runta @a16z let's gooo!

@runta @a16z Congrats!!

@runta @a16z 💪💪congrats!

@runta @a16z Congratulations @guanlan runta feels like the best of Daytona and Modal, but purpose-built for the execution layer AI agents.

@runta @a16z Congratulations!

@runta @a16z Is it kinda a replacement for k8s / docker or how does it work with them?

@runta @a16z wait, can agents finally be trusted in prod?

@runta @a16z is runta like @e2b, but with guardrails?

@runta @a16z Congrats on the hard launch!

@runta @a16z Thank you Jacky for the help along the way.

@runta @a16z Exciting work!

@runta @a16z 🔥🔥🔥

@runta @a16z Congrats on the launch!

@runta @a16z Congratulations @guanlan

@runta @a16z Let’s go! just the beginning!!

@runta @a16z runtime constraints on agents are the unsexy but necessary layer before any real on-chain deployment scales. without solid guardrails the autonomy hype collapses the moment one bad loop drains value. runta focusing here feels like the infrastructure piece most agent plays skip.

@runta @a16z Congrats!

@runta @a16z Congratulations on this massive Seed round Guanlan. This is definitely a huge step forward for Runta.

@runta @a16z Go Guanlan!!

@runta @a16z congrats!

@runta @a16z Congratulations Guanlan and team! Hope to be able to build with @Runta soon. Also, it will be a pleasure to connect in person.

@runta @a16z lfg, reminds me of temporal but for agents
