Profile
Fireworks AI provides cloud infrastructure and tools for developers to run, fine-tune, and deploy open-source AI models at scale.
Fireworks AI is an inference infrastructure company that provides developers with access to open-source AI models and the compute to run them. Founded in 2022 by former Meta engineers who worked on PyTorch, the company has grown rapidly on the thesis that enterprises would prefer to own and customize their own AI rather than rely on a handful of closed API providers. As of October 2025, Fireworks AI had raised $327 million in total funding, including a $250 million Series C at a $4 billion valuation co-led by Lightspeed Venture Partners, Index Ventures, and Evantic, with participation from Sequoia Capital, NVIDIA, AMD, MongoDB, and Databricks.
By May 2026, Bloomberg reported the company was in talks to raise another round at a $15 billion valuation, nearly quadrupling its prior price tag. The platform processes over 10 trillion tokens per day and claims annualized revenue above $280 million, serving more than 10,000 companies. Customers include Samsung, Uber, DoorDash, Notion, Shopify, Upwork, Cursor, Vercel, Cognition, Genspark, HubSpot, Quora, GitLab, UiPath, and others.
Fireworks does not build its own chips but gives customers virtual access to GPUs from NVIDIA and others, combined with an inference engine it claims delivers up to 40x faster performance and 8x cost reduction versus alternatives. The company is investing in hiring over 150 new employees across research, engineering, product, and sales, and acquiring additional GPU capacity. Competitors include Baseten Labs (valued at $5 billion in January 2026) and Fal (valued at $4.5 billion in December 2025).

Strengths and what to watch
Strengths
- Rapid revenue growth: annualized revenue surpassed $280 million as of October 2025, up from an undisclosed base at Series B in July 2024.
- Deep investor backing from top-tier firms (Sequoia, Lightspeed, Index, Benchmark) and strategic partners (NVIDIA, AMD, MongoDB, Databricks).
- Strong customer roster with multiple well-known logos across different verticals, indicating broad market pull.
Watch for
- Valuation leapfrogging: from $552 million in July 2024 to $4 billion in October 2025 to a reported $15 billion target in May 2026 — each round raises expectations for continued hypergrowth.
- Competitive pressure from well-funded inference rivals like Baseten ($5B valuation) and Fal ($4.5B), plus chipmakers (Groq, Cerebras) and cloud giants (Amazon, Qualcomm) designing their own inference silicon.
- Enterprise adoption lag: analysts note roughly 80% of enterprises have not yet reached the advanced stage of AI deployment that requires a platform like Fireworks, limiting the near-term addressable market.
