Willow Voice AI

Willow is a San Francisco-based AI voice dictation platform that enables professionals to write anywhere on their computer — in any app, message thread, or document — using natural speech at up to 4x typing speed. Founded by Allan Guo, Lawrence Liu, and Ian Ye after dropping out of Stanford, Willow graduated from Y Combinator's X25 batch and rapidly scaled to $100k+ ARR within two weeks of launch. The platform uses sub-200ms speech processing, removes filler words automatically, adapts to each user's writing style over time, and supports 100+ languages. Willow is available on Mac, Windows, and iPhone and is trusted by 100,000+ professionals. In July 2025 the company raised $4.2M. Enterprise features include SOC 2 Type II certification, HIPAA compliance, zero data retention, and team-wide voice copilot deployment. The product also includes Willow Scribe, which converts rough spoken intent into polished written output.
