A small studio building focused software for developers, teams, and UK businesses.
We ship compliance SaaS, mobile apps, browser extensions, and developer tools — plus open-source libraries in the gaps we hit ourselves. No venture capital, no growth-at-all-costs. Just well-crafted products that solve real problems.

Open source
Libraries we’re planning to release
Shortlist of open-source libraries we intend to build alongside our products — in gaps we’ve hit ourselves and think are worth closing for the wider developer community.
MCP Observe
PlanningEmbeddable observability and audit SDK for MCP servers.
OpenTelemetry-native middleware any MCP server can drop in — per-request audit trails conforming to the Jan 2026 gen-ai/mcp semantic conventions, with a separate cryptographically hash-chained audit plane and redact-by-default privacy. Fills the gap between protocol-level plumbing and K8s-scale gateways.
EvalGate
Coming soonHeadless LLM evals as a CI gate. Cached, reproducible, fast.
Pytest-native (and TS-native) eval runner designed for pull-request gating, not dashboards. Golden fixtures, diffing, small-model judge routing, cost-aware execution, and GitHub Actions summaries.
ComplianceCore
Coming soonOpen-source Vanta/Drata alternative for SOC2, ISO 27001, EU AI Act.
Evidence automation as an integration layer — AWS/GCP/Okta/GitHub connectors, an evidence database, and policy-as-code. Built for the EU AI Act tailwind and the long tail of teams priced out of commercial compliance SaaS.
