How we
build
Fenrir is a product studio. We build AI-native software end to end — and run it in production. This is the craft behind the flagship.
Claude-Native Engineering
We architect software around Claude from the first line — skill systems, structured context, and tool use designed so the AI is a reliable component of the product, not an afterthought bolted to the side.
Autonomous Agent Systems
We design and operate fleets of autonomous AI employees — scoped tools, guardrails, scheduling, and orchestration — running real operational work day to day. We ship the agent patterns we've already proven in our own back office.
Full-Stack Product Build
Design, frontend, backend, data modeling, and everything in between. A studio owns the whole stack of what it makes, so the AI layer and the product around it are built as one system.
Integrations & MCP
We connect AI to the systems it needs to be useful — APIs, data stores, and external tools via the Model Context Protocol — so an agent can actually do the work, not just talk about it.
Security & Infrastructure
Built on enterprise security discipline — identity, access control, and cloud architecture hardened for production. Good AI only matters if it's safe to put in front of real users and real data.
Operate, Not Just Deliver
We run what we build. The studio's flagship and its internal systems are live in production under our own operation — the same standard we hold any build to.
The proof
We build it, then we run it
FaciliTrades is the studio's flagship — an AI-native barter marketplace, live in production, operated by the same team that built it. Behind it runs a fleet of autonomous AI employees handling the studio's own operations. The patterns aren't theoretical; they're shipping.

Most of our energy goes into our own products. We do take on a small number of build partnerships — AI-native work where the studio's craft is the right fit — by referral. If that's you, tell us what you're building.
