Fireworks AI operates an inference platform designed to simplify how developers build and deploy generative AI applications. Founded in 2022, the company provides end-to-end model lifecycle management - from building and tuning to scaling - with support for open-source models across multiple use cases including code assistance, conversational AI, enterprise retrieval-augmented generation, and multimodal workflows.
The platform processes over 13 trillion tokens and has been independently benchmarked as the leader in LLM inference speed. It runs on globally distributed virtual cloud infrastructure and powers production systems for companies including Sourcegraph, Notion, and Cursor. A multi-year partnership with Microsoft Azure Foundry extends its reach to Azure customers worldwide.
Fireworks AI raised $252 million in Series C funding at a $4 billion valuation, backed by investors including Benchmark, Sequoia, Lightspeed, Index, and Evantic. The founding team includes veterans from Meta PyTorch and Google Vertex AI.
