Founded by dyslexic Brown University student Cliff Weitzman and his brother Tyler, the company grew from a personal reading aid into an AI voice empire spanning consumer apps, a voice cloning and dubbing studio for creators, and a text-to-speech API for developers. It serves 50+ million users across mobile, Chrome extension, and desktop, offers hundreds of voices in 50+ languages, and won the 2025 Apple Design Award for Inclusivity.

Cliff Weitzman
Cliff Weitzman is the founder and CEO of Speechify, the text-to-speech app that reads anything aloud in natural AI voices and now serves over 56 million users in 200+ languages. Diagnosed with dyslexia in third grade, he taught himself English by replaying a Harry Potter audiobook 22 times, then built the software he wished he'd had to keep up with the reading load at Brown University. What began as a personal hack for one dyslexic student became a Forbes 30 Under 30 company and an Apple Design Award winner.

Lily Clifford
Lily Clifford is the CEO and co-founder of Rime, a San Francisco-based voice AI company building enterprise-grade text-to-speech models with a linguistic edge. A Stanford NLP PhD dropout with a background in sociophonetics, she left academia in 2023 to prove that AI voices could sound like a friend rather than a voice actor. Rime now powers over 100 million phone conversations monthly for brands like Domino's and Wingstop, having raised $8.6M in total funding. Her counterintuitive thesis - that slightly 'bored' voices outperform perfectly polished ones - has become the foundation of a fast-growing enterprise voice platform.
