About

Featherless.ai (formerly Recursal.ai, renamed February 2025) is a serverless AI inference platform that provides access to over 30,000 open-source AI models spanning language, vision, audio, and multimodal applications 123. The company was founded in 2022 and is co-led by CEO Eugene Cheah, CTO Harrison Vanderbyl, and COO Wesley George 4. Featherless positions itself as “a neutral layer for open AI, independent of hyperscalers and proprietary ecosystems,” with infrastructure spanning the EU and US and team locations across San Francisco, Toronto, Singapore, and Europe 2.

On April 30, 2026, Featherless.ai announced a $20 million Series A co-led by AMD Ventures and Airbus Ventures, with participation from BMW i Ventures, Kickstart Ventures, Panache Ventures, and Wavemaker Ventures 13. The company plans to use the capital to scale global infrastructure, launch a marketplace for specialized open models, and deepen integration with diverse hardware architectures, including a strategic collaboration with AMD to ensure popular open-source models run natively on AMD ROCm 13. Featherless previously raised a $5M seed round announced in March 2025 5.
