C10UD LLC

An engineering studio that builds its own infrastructure.

We design and operate the systems our products run on — the agent runtime, the scheduler, the edge, the secret store. Nothing is glued together from other people’s platforms, which is why we can move on problems most teams have to wait out.

Built in house

Every layer we depend on is written and maintained by us. When something breaks at 3am, the person who wrote it is the person fixing it.

Research first

Each product starts as an internal tool solving a problem we hit ourselves. It only leaves the lab once we have run it in production for months.

Deliberately quiet

We publish what a system does and what it is for. How it works stays internal.

What we build

Agent runtime

Ghost

A runtime for coding agents that keeps working when you close the laptop.

Ghost is the platform our engineering work runs on. It turns a model, a repository and a set of tools into a durable, server-owned session you can leave and come back to — from a terminal, a browser, or a phone on a bad connection.

Compute platform

Cluster

Anycast edge, regional control planes, and workloads that wake on request.

Our compute layer: scheduling across regions, isolated workloads, service discovery, secret delivery, and idle capacity that costs nothing until a request arrives.

Email infrastructure

Mailstack

Our own mail plane: sending, receiving and submission, each on its own legs.

Mailstack is how everything we run sends and receives email. Three separate services — outbound delivery, inbound reception, and authenticated submission — each with its own tenants, its own limits and its own failure domain.

Build pipelines

Anvil

A build server small enough to understand, honest enough to trust.

Anvil runs every build we ship, including this site. Pipelines are declared in the repository, each build gets its own workspace and streams its logs live, and the machines that execute them exist only while there is a queue.

Research

In the lab

Tooling we are still living with before anyone else has to.

A handful of internal systems are in the same pipeline Ghost went through — used daily, hardened quietly, named publicly only when they are ready.

Unreleased

Working with us

We are a small team shipping our own infrastructure and the products on top of it. If you want to know what we are running, or what we could run for you, write to us directly.
