Raycaster is the first AI-native document workspace (Cursor for Documents) for high-stakes work, starting in life sciences (CMC, quality, regulatory). Instead of 47 versions of a Word doc in someone’s inbox, customers get a single living dossier: thousand-page PDFs, flows, and clinical data in one place - searchable and kept in sync.

We’re backed by YC, leading life sciences investors (behind companies like Oscar Health and Mammoth Bio), and execs from Definitive Healthcare, Colossal Biosciences, and IQVIA. We’re already working with enterprise customers globally.
