About this role
About OptexityOptexity is a product-driven research lab building clinical reasoning and computer use models for hospitals and clinics. We are building world class search and chat system for doctors to help them find information quickly and elevate the level of care. We deploy directly inside clinics and hospitals — including systems with no APIs, using integration infrastructure we've built and open-sourced — and in return become their preferred partner. That gives us proprietary clinical reasoning trajectories from practicing physicians, and a feedback loop between real patient encounters, our models, and the products built on top of them.
We're a small, fast-moving founding team with multiple published papers in NeurIPS, ICML, CVPR etc and background from Apple, Amazon, Microsoft, CMU, IIT.
We are backed by world-class investors and leaders like Jeff Dean, Neotribe VC, PearVC, Together Fund and Zapier Fund.
How we workCustomer obsession — we start with the customer and work backwards
Intellectual honesty — ideas matter more than titles; we communicate directly and assume good intent, even in disagreement
Bias for action — we build and learn with customers rather than debate in the abstract
Extreme ownership — we own outcomes, not just tasks, and see problems through
