We build the AI into your software.
stbrn studios is a security-first AI studio. We design and ship AI features — copilots, voice, agents, private retrieval — end to end, on infrastructure you control. And we build our own AI products in the open, so you can see how we work before you hire us.
We help founders and small teams put real AI into their software — the useful kind, built securely, with senior engineering from the first line to production.
What we build.
AI Product Engineering
Intelligent features built into your product, end to end — the model work plus the backend, interface, deployment and monitoring around it. Senior engineering across the whole stack.
Secure & Private AI
AI over your own data, on infrastructure you control — permission-aware retrieval with citations, kept auditable and out of third-party training. The thing off-the-shelf tools can't promise.
Fractional AI Engineer
Your on-call AI engineering team without the headcount — ongoing capacity to design, build, harden and improve AI features, month to month, on a retainer.
AI Build Sprint
The way in: a short, paid engagement to scope one AI feature, prototype it against your real data, and hand you a plan you own — with a security read included. Build it with us or take it in-house.
We don't pitch. We ship — in the open.
Echo
A voice journal that turns what you say into clean, structured entries — transcribed, summarised and refined, privacy-first by design.
Follow along >Coding Agent
A desktop app that runs the coding agents we use daily — Claude Code, Codex, OpenCode — behind one clean interface. Built in public.
Follow along >AI Interview Platform
Practice interviews with an AI interviewer that actually pushes back — realistic questions, real-time feedback, and honest scoring.
Follow along >Scope, build, ship.
Scope.
We pin down one AI feature worth building — what it does, what data it touches, and how we'll know it works. You get a costed plan you own, whether or not you build it with us.
Build & harden.
We build it against your real data — model, backend, interface — with evaluations and security baked in from the start, not bolted on at the end.
Ship & care.
It goes live on infrastructure you control. Then we stay on to monitor it, improve it, and keep it honest as your needs change.
Tell us what you're building.
An AI feature for your product, a private assistant over your own data, or an idea that needs a first working prototype — send us the shape of it and we'll tell you honestly if and how we can help.
