About Novellia

Novellia provides US patients free access to nearly a decade of consolidated health records from multiple providers, updated automatically. Founded in 2023 and headquartered in New York, the company is building both the technical infrastructure to ingest and normalize healthcare data at scale and a commercial data science function to extract actionable insights. Current projects span backend service hardening, LLM-powered insight generation, observability tooling, and early-stage marketing and growth infrastructure. The team is small (11–50) with senior and lead-level hires concentrated in engineering and data, reflecting the stage of scaling technical foundations before mass patient acquisition.
