The name
Interchouette is a French pun: Internet, c’est chouette ("the Internet is cool"). ITC stands for Information Technology Company. Based in Hilversum, Amsterdam, and Paris.
The house bias is Rust-first systems work (Wasm, APIs, MCP, markets tooling) with clean architecture, tests that stay honest, and shipping things that are fun to use. Public code lives on Interchouette-ITC.
