Featherless AI

Featherless AI is the largest open-source LLM inference provider on Hugging Face, founded in 2024 and led by CEO and co-founder Eugene Cheah. The company offers serverless access to over 30,000 open-source models on a flat-rate pricing model, abstracting GPU infrastructure complexity for developers and prosumers who want to run AI models without managing hardware. Cheah co-created RWKV, the first attention-free AI architecture under the Linux Foundation, and the company grew out of that research community as an accidental pricing experiment that quickly outpaced the original platform. As of April 2026, Featherless AI serves 10,000 customers, generates more than $250,000 per month in revenue but less than $500,000 per month, and has a team of 27 people approaching 30. The company raised a $2 million seed round pre-launch for RWKV research, then closed a $20 million Series A in December 2025 led by Airbus Ventures and AMD Ventures. Its largest single customer pays between $1 million and $2 million per year. The single most important strategic fact is that Featherless AI built its inference stack from scratch to load models in 5 to 30 seconds, versus the industry-standard 30 minutes, enabling dynamic GPU swapping across thousands of models on demand. This technical moat lets the company serve the long tail of fine-tuned and niche-language models that no other provider hosts, which is what drove the initial Reddit-fueled signup surge and continues to differentiate it from competitors who cover only the top 100 models.
