Willow

Willow is a technology startup headquartered in Palo Alto, California, founded in 2025 by Allan Guo and Lawrence. The company focuses on advancing human-computer interaction through its development of fast, context-aware, privacy-first voice technologies. Initially exploring voice solutions for assisted living, Willow pivoted toward healthcare by creating AI-driven medical scribes to improve clinician documentation efficiency. This pivot led to broader applications of their voice dictation technology aimed at users who spend significant time typing.

Willow’s flagship product, Willow Voice, leverages on-device AI and advanced speech recognition to deliver significantly improved accuracy and ultra-low latency compared to legacy voice tools. The company's vision is to build a "voice OS to replace the keyboard," which emphasizes privacy and workflow adaptability across various writing contexts such as email, documentation, and messaging. Willow operates a freemium SaaS business model, providing free access alongside planned premium features and team plans. As an independent, Y Combinator-backed startup in its growth phase, Willow currently employs two people with plans to expand its team.
