AI & Machine Learning Operationalization (MLOps) Software
Featherless AI is a serverless open-source large language model inference provider founded in 2024 and headquartered in North America, with data center capacity in Europe. The company offers developers and prosumers instant access to a catalog of 30,000 open-source models, with a target of 100,000, through a flat-rate monthly subscription starting at $25 per month plus usage-based scale-up plans.
The company grew out of RWKV research conducted under the prior entity Recursor, which was sold in 2024. Featherless AI was initially a pricing experiment that quickly outpaced the original platform in revenue, prompting the founders to pivot fully. The company closed a $20 million Series A in December 2025 led by Airbus Ventures and AMD Ventures, bringing total funding to $22 million across a seed round and the Series A.
As of April 2026, Featherless AI serves more than 10,000 customers, generates more than $250,000 per month in revenue, and employs 27 people. The company's core technical differentiator is a proprietary inference stack that loads models in 5 to 10 seconds, compared to roughly 30 minutes for traditional infrastructure providers, enabling dynamic model swapping across a shared GPU pool and supporting far broader model coverage than competitors.
