Steven Webster - When Fitness Products Start Acting Like Coaches
Steven Webster thinks fitness products have become too obsessed with scores and dashboards. His alternative is much closer to the way a coach actually works: observing what's happening, understanding the context and stepping in when needed. That idea runs through much of what ASENSEI is building with movement recognition and AI. Steven joins Marco and Jonas to talk about moving from apps to agents, the proprietary language ASENSEI built to describe human movement, and why that language became unexpectedly valuable with LLMs. They also get into the product decisions behind a 12-year journey: building toward technology that didn't exist yet, letting customers influence the roadmap without simply reacting to requests, deciding what not to build, and making an early bet on on-device AI.
