Trapper Markelz
Chief Product Officer
Trapper Markelz is a startup veteran and product leader who has spent 25+ years building software from idea to production. He does his best work at the earliest stage, shipping a new product and working with customers until it finds product-market fit.
His career has centered on one problem: turning scattered data into information people act on. At 360voice, a company he co-founded, he built a service that used machine-generated narrative from raw data. As VP of Products at GamerDNA, he pulled player data from dozens of separate games into unified profiles and recommendations. At MeYou Health, where he served as Chief Product Officer, Chief Operating Officer, and Chief Executive Officer, he built clinically validated digital health programs that got millions of people to form healthier daily habits. As Chief Operating Officer of Beamable, he ran a backend platform that game studios used to build and scale their live products. He also co-founded Modi Boxi, a Kickstarter-funded 3D printing product and community.
BioRadar brings those threads together. Trapper leads product and the platform that aggregates wastewater metagenomics, syndromic surveillance, behavioral, and open-source data, turning it into AI-driven briefings for public health agencies.
Trapper completed the General Management Program (GMP 18) at Harvard Business School and holds a degree in Information Technology from Rochester Institute of Technology. He is also a published poet, with work in more than 30 magazines and two collections, and serves on the advisory board of the New England Poetry Club.
