We're building the runtime agents were missing.
Superserve orchestrates millions of microVM sandboxes. Fast enough to spin up per LLM call, durable enough to keep an agent's filesystem alive for weeks, and isolated enough that the code inside them doesn't matter.
The infrastructure agents were never given.
// 2023. The agent stack started looking like this:const stack = { reasoning: "miraculous", tooling: "shipping weekly", runtime: "a 15-minute Lambda or a leaky container",};// Models could write code, plan, browse, debug. But the place they ran in// timed out, lost state, or shared a kernel with someone else's sandbox.// We built Superserve so that the runtime stops being// the part of the stack that breaks first.+ Sub-300ms cold starts, on a per-call microVM.+ Real virtual filesystems. sqlite, pnpm, ffmpeg, 5GB datasets.+ Snapshots that survive process death, region failure, and 30 days idle.+ Hardware isolation, every call. The model can't escape.// And the same thing, in your own cloud, on your own bill, if you need it.Four things we don't compromise on.
Reliability is the feature.
Agents that disappear at 24h, time out at 15m, or quietly drop file writes are not actually working. We optimize for the boring metrics: p99 latency, sandbox survival rate, snapshot durability.
Security is not a checkbox.
Every sandbox is a hardware microVM. No shared kernels, no "trust the user" escape hatches. We assume every line of code we run is hostile, because for our customers it usually is.
Open by default.
Our SDK, CLI, and benchmarks are MIT-licensed. Our control plane runs in your cloud if you want it to. Lock-in is a tax on customers, not a moat.
Talk to the product, then to humans.
You should be able to ship to production without a sales call. When you do need it (incident at 3am, custom region, weird workload), a human picks up.
Trusted by teams running real agent workloads.
"We replaced our in-house container pool with Superserve in a weekend. Cold starts went from 4 seconds to under 300ms, and we stopped getting paged when long-running agents hit the 24-hour wall. It's the boring kind of infrastructure win. Everything just works."
What we do, not what we promise.

A short history.
Founding
Three of us (ex-Anthropic infra and two from a Firecracker-shop) got tired of watching agent demos die at the 24-hour mark. Started prototyping in a basement in SF.
Private beta
First 12 design partners. Ran 4M sandboxes in three months across coding agents, RL training, and a stealth biotech doing simulation rollouts.
Seed round
$8M from Felicis, Conviction, and a handful of agent-platform founders. Hired the first 6 engineers. Shipped snapshots & forks.
GA + open source
Public launch. Open-sourced the SDK, CLI, and our benchmark suite. SOC 2 Type II audit complete.
Self-hosted GA
BYOC general availability. Three Fortune-500 banks and one US-Federal agency now run Superserve inside their own VPC.
Built by people who've broken this before.
Backed by people who have shipped infra.
Plus angel investments from founders of Vercel, Cloudflare, Modal, Stripe, and Replit.
Help us build the runtime agents deserve.
We're a small team, in-person three days a week in SF, remote-friendly for the rest. We hire seniors, pay above market, and ship to production every day.
