About
WaveForms AI is an audio AI company founded in 2024 by former OpenAI researcher Alexis Conneau and Coralie Lemaitre, aiming to build end-to-end audio language models that pass the speech Turing test. The company's technology is designed to understand and replicate not just speech content but emotional nuance, enabling AI voices that feel genuinely human. WaveForms raised $40 million in seed funding led by Andreessen Horowitz at a $200 million valuation in December 2024. The company was subsequently acquired by Meta in August 2025 to bolster Meta's audio AI capabilities.
