Independent product studio · Enschede
We design and build focused products: Android apps, connected hardware and AI systems whose behaviour can be inspected instead of merely trusted.
Two projects, one recurring instinct: find the part that has to work in reality and build outward from there.
Hold the split. Let the rate settle.
Live coaching for Concept2 rowers. Ergomi connects to the machine, understands the workout while it happens and speaks when the next cue can still matter.
Open Ergomi ↗A public benchmark and private evidence run for AI coaches, companions and wellbeing products. It tests what repeated contact reveals and single-turn evals miss.
Read the method ↗TukkerWorks is Marcel Maatkamp’s product studio. The work ranges from low-level hardware communication to voice coaching and long-horizon behavioural evidence.
The common method is simple: name the riskiest assumption, make it touch reality early, and keep the useful version smaller than the pitch.
Good. Send the awkward version before it turns into a polished roadmap.
