§ 03 — Receipts

No testimonials. Receipts.

Every number on this page links to its public source. If you can't click it and check it yourself, it doesn't belong here.

Five receipts, one click each.

Live · Dogfooding

FotoboxApp × meinefotobox.ch

Operations software for photobooth rental businesses: bookings, prints, gallery delivery, revenue — one dashboard. The stress test: the same software runs a real rental business in Switzerland at meinefotobox.ch. If the software goes down, the business goes down.

Live

AirConnect

Operations and logbook software for flying clubs and airfields: bookings, fuel, maintenance, pilot records. An industry where traceability is not optional — maintenance and flight data have to be right, every day.

The receipt: air-connect.ch
Live · AI pipeline

AudioEmpire

AI-assisted audiobook production — from idea to published audiobook. The proof that the pipeline produces instead of merely demoing: four audiobooks made with it are in the public stores (Spotify, Apple Books, Google Play).

Open source

HelloDATA BE

Open-source enterprise data platform (dbt, Airflow, Superset) built for the Canton of Bern — Nicolas helped build it. The entire codebase is public, every commit on the record. 266+ GitHub stars as of July 2026.

Live

Anvil

Tickets in, software out: Anvil orchestrates 58+ specialized AI agents and turns Jira, GitHub or Trello tickets into implemented, tested and deployed code — the multi-agent craft behind our engagements.

The receipt: anvil-coder.tech

The audit principle

Testimonials can be bought and logos can be rented. So we show things that can't be faked instead: running software, public code, published products, a commercial-register entry.

Engagements run on the same principle: you get repo access, test suites and deployment logs — not slides.
