Hi, I'm Marcus Rydberg

Twenty years building systems that find the signal in messy, heterogeneous, real-world data — a real-time news search engine (Stockholm, 2005), a national entity graph written from scratch in Java, clinical data across hospital systems that don't talk to each other, and now LLM agents.

Now

  • True North Family AI — one question across four frontier models, the models critiquing each other, one synthesized answer. Family accounts with parental approval. Designed, built, and shipped solo in six months — Go, SvelteKit, native iOS & Android.
  • agentic-toolkit — three tools for running AI coding agents on real work: a deterministic chat front door, a durable campaign runner, and multi-model review with adjudication.

Before

Co-founder & CTO of Luminare (12 years, Texas Medical Center): sepsis prediction built inside Mayo Clinic's data lake, a COVID pivot that won public contracts head-to-head against Salesforce and Epic, and a platform ultimately acquired by its largest customer, Dallas County — where I now lead its buildout and integration.
