Our story

From a kitchen counter to the world stage

Yanyan and Rennan are engineers who love coffee. We spent years in R&D building record-breaking electric race cars and sensor technology, then turned the same mindset on our grinder. What works for champions works at home.

The team

The people behind CremaLoop.

  • Sierra

    Sierra

    The Champion

    Brewers Cup Champion in Switzerland (2026) and the UK (2022). As our R&D and sensory specialist, Sierra tastes the difference: every prototype has to pass her cup.

    The MVP Builder & Operator

    David turns new ideas into the first working version, then keeps CremaLoop running: production, testing and customer support.

Our mission

Tools that make a difference

  • Data, not hype

    We measure before we make a claim.

  • Tested where it's hardest

    Prototypes go through competition-level testing with Sierra.

  • Designed in Switzerland

    Prototyped and tested in our workshop in Winterthur.

  • Built to last

    Spare parts are sold separately, so you upgrade instead of replacing.
