Summary
🤩
Rockstar🎓
Top SchoolToni Rosiñol is a PhD-trained robotics and AI founder based in San Francisco with a decade of experience, co-founding Stack AI (YC W23) to deliver enterprise GenAI for IT. He bridges research and product: his MIT-era SLAM and geometry work surfaces in open-source contributions to GTSAM, NeRF‑SLAM and Kimera (including low-level Jacobian/retraction and cheirality fixes that improve geometric robustness). Toni combines hands-on systems engineering with customer-facing leadership—running customer support/CEO duties at Stack AI while also investing as an angel. His background spans high-stakes perception work (JPL DARPA SubT) to commercial hardware success (Velohub’s Blinkers, 3k+ units sold), reflecting a rare ability to take complex research into real-world products.
