About

The human behind the code

Arnaud Altenburger

Engineer by training, project manager by passion, builder by nature. After 8 years at Canal+ orchestrating technical transformations on high-volume critical systems, I chose independence to do what I love most: build.

Today, I split my time between technical orchestration consulting for my clients and building my own products. Instant Chef and The Guild were born from a simple conviction: our society is evolving, not always for the better. And technology has a role to play when put in service of the right questions.

I don't sell time. I sell transformation.”

Expertise

A 360° vision

Where a developer sees code and a project manager sees deadlines, I see the entire system.
