We build
AI-native products.
Fenrir is a product studio. We design, build, and run software with AI at its core — starting with our flagship, FaciliTrades.
What we do
A studio ships
what it builds.
We own what we make — from the first design decision to the production system running in front of real users. We build with Claude-native engineering and autonomous agents, then operate the result ourselves. The proof is a live product.
The flagship
A barter marketplace where people trade goods and services directly — no money. AI handles the hard part: matching what you have to what you want, and chaining multi-party trades that wouldn't happen one-to-one.
How we build
Engineered, not prototyped
The studio runs on the same craft it builds with — production AI systems, not demos.
Claude-Native Engineering
We architect software around Claude from the ground up — skill systems, tool use, and structured context that make AI a dependable part of the product, not a bolted-on chatbot.
Autonomous Agents
We run our own back office on a fleet of autonomous AI employees — operations, research, and monitoring — so we ship the agent patterns we've already proven in production.
Full-Stack Product
Design, frontend, backend, data, and cloud infrastructure under one roof — built with the same engineering discipline that secured identity systems for millions of users.
