Top Tech Startups in Greenwich, CT in 2027

NeuralFrame is a 25-person, venture-backed healthcare software company led by a proven IPO team. We’re reimagining how medical knowledge is captured and shared—leveraging large language models, retrieval-augmented generation, and advanced data pipelines to turn complex, messy clinical text into precise, structured insights. We work on high-impact challenges at the intersection of medicine and technology: clinical language understanding, knowledge graph design, predictive analytics, and intuitive workflow tools. Our platform powers critical hospital functions—from cancer registries to automated case finding—unlocking new levels of accuracy, speed, and research potential. In 2024, the U.S. Department of Veterans Affairs awarded NeuralFrame a contract for cancer registry modernization software. Our engineers build in Rust, Python and SQL on AWS. We’re now building a new clinical data platform from the ground up, with a Rust data engine at its core. We care about correctness: typed code, real tests, careful code review, and verifying AI-assisted code rather than trusting it. No healthcare background is needed to join; we teach the domain. If you want to solve meaningful problems with a team that moves fast, ships often, and builds products that make a real difference in patient care, you’ll fit right in.
