Willow

Willow is a San Francisco startup building voice-first interfaces that turn natural speech into polished text across every app on Mac, Windows, and iPhone. Founded in 2024 by Stanford dropouts Allan Guo and Lawrence Liu and backed by Y Combinator, Willow promises roughly 3x the accuracy of built-in dictation with ~200ms response time, automatic filler-word removal, style-matching, and an AI mode that reshapes rough spoken notes into finished messages. The company raised $4.2M in seed funding and has grown roughly 50% month over month, with early enterprise users including Uber, Heidi Health, and Zego.
