We are a venture backed software company building Spacetime, the realtime backend platform.
What we build

The whole backend, in one place.

Spacetime replaces the stack you would otherwise assemble yourself.

Realtime backend platform

Spacetime

Write your schema and business logic as a module in Rust, C#, TypeScript, or C++. Spacetime compiles it, runs it inside the database, and keeps every connected client up to date in real time. No separate servers, no caches to invalidate, no sync layer to write.

  • DatabaseYour state lives in one place, in memory, always durable.
  • Server logicYour code runs inside the database, not next to it.
  • AuthIdentity and permissions come built in.
  • Realtime syncEvery connected client updates the moment state does.
  • Rust
  • C#
  • TypeScript
  • C++
Our focus

Precision engineering, applied to software.

One platform, held to the standard the hardest workloads demand.

Systems that hold up

Spacetime carries the database, the server logic, auth, deployment, and realtime sync in one place. When everything sits behind a single system, that system has to be right, so correctness comes first and everything else follows.

Built under real load

We do not ship a platform we have not run ourselves. Spacetime holds up a live world with a whole society of players inside it, which is how we find the hard problems before our users do.

Where Spacetime came from

A game we could not build any other way.

BitCraft Online is our own MMORPG, a single sandbox world every player shares. No library or framwork was available that could host and run a world like that, so we built Spacetime to do it. BitCraft still runs on it, which is how we find the platform’s limits before our users do.
