Privacy, traceability and responsible use are part of the build, not a review at the end — daily work in the team behind Kyan Health's wellbeing assistant; in Oval Brief, a pipeline tuned for public-policy documents scores each one for impact, assigns its topics and assesses who is affected, in factual, non-partisan terms; in KeyTwelve, what the documents can't support is withheld, not guessed
“He draws from his intrinsic nature to look at every aspect of the business as an owner and does so with innate humanity and flawless execution.”
“I first worked with Hans at Fountain Life, where he led the development team building our 100+ service healthcare platform. Years later I brought him in to build HealthLab's outbound voice agent — the full streaming loop from telephony through speech recognition, model, and synthesis. In both, he was fantastic to work with, knowledgeable, quick to guide the team to adapt to new technologies, careful in his technology choices, and great to brainstorm with through complex challenges to get to elegant solutions.”
“What I valued most working with Hans wasn't the speed. It was that he knew which parts of the system to let an agent near and which to handle himself. That judgment is the scarce thing right now, not the tooling.”
