Infrastructure,
built to be trusted.

Beyond our own applications, we build infrastructure for other teams — MCP servers, APIs, and purpose-built backends.

01 — MCP Servers

Tools you and your
AI can rely on.

Model Context Protocol servers that expose your data and actions to AI models safely — typed, scoped, and observable from the first request to the last.

Discuss a server
01
Tool & resource design

Ergonomic tool surfaces that models actually use correctly: clear names, tight scopes, helpful errors.

02
Typed schemas

Inputs and outputs validated against strict schemas, so behavior is predictable and debuggable.

03
Auth & scoping

Per-client credentials, least-privilege access, and audit trails for every action taken.

04
Observability

Structured logs, traces, and metrics. You can see exactly what the model asked for and why.

05
Transport

stdio for local tools, streamable HTTP for hosted deployments. Built to the current spec.

02 — APIs & Interfaces

Contracts that
don't surprise you.

REST and event-driven APIs with documentation worth reading, sensible defaults, and versioning that never breaks a client without warning.

Talk through an API
01
REST & RPC design

Resource models that map cleanly to your domain, with consistent conventions throughout.

02
Webhooks & events

Reliable delivery, signed payloads, and replay keep integrations in sync.

03
SDKs & docs

Typed client libraries and reference docs generated from the source of truth.

04
Versioning

Additive by default, deprecations announced early, migrations made painless.

05
Rate limits & quotas

Usage limits and quotas documented up front, so consumers of your API know exactly what to expect.

03 — Product Engineering

From a sketch
to something shipped.

For businesses with a product to build, we take engagements end to end — design, build, launch, and the long maintenance after.

Start an engagement
01
Discovery

We pressure-test the idea, define the smallest valuable version, and agree on what "done" means.

02
Design

Interface and system design in lockstep: what it looks like and how it holds up are decided together.

03
Build

Short cycles, working software early, and nothing held back for a big reveal at the end of a sprint.

04
Launch

App Store submission, infrastructure, and the unglamorous details that make a release stick.

05
Maintain

We stay on. Software is never finished, and we treat upkeep as part of the work.

Let's scope it together.

Send us the problem — an MCP server, an API, a product that needs building. We'll tell you whether we're the right studio for it.
