Fireworks AI, the enterprise AI inference platform built by former PyTorch engineers, closed a $250 million Series C funding round at a $4 billion valuation in October 2025.
The round was co-led by Lightspeed Venture Partners, Index Ventures, and Evantic, with continued backing from Sequoia Capital, along with strategic investments from tech giants NVIDIA, AMD, and Databricks.
This latest injection brings the company's total capital raised to $327 million since its 2022 inception.
The AI Infrastructure Built by Meta Veterans
Fireworks AI emerged from the minds of the PyTorch team at Meta. CEO and co-founder Lin Qiao, who previously led PyTorch development at Meta, joined forces with six other Meta and Google AI veterans to launch the company in 2022.
The platform tackles a critical bottleneck enterprises face: deploying AI models in production environments with speed and cost efficiency.
Rather than forcing companies to hand over their data to generic cloud providers, Fireworks gives businesses full control over their AI infrastructure.
Uber, Shopify, DoorDash, Notion, Cursor, and GitLab are among the major enterprises already running production AI workloads on the platform.
Fireworks AI Funding Overview

Why This Funding Round Changes Everything?
The AI industry is experiencing a fundamental shift from model training to inference optimization. Inference represents the production phase where trained AI models make real-time predictions and decisions, which demands lightning-fast response times for consumer-facing applications.
Fireworks AI has positioned itself at the center of this transition. The company processes 140 billion tokens daily with 99.99% API uptime.
Their proprietary FireAttention technology delivers inference speeds 4x to 15x faster than open-source alternatives. The fresh capital will accelerate enterprise adoption and cement Fireworks' position as the infrastructure backbone for production AI systems.
Companies can now deploy over 100 state-of-the-art models across text, image, audio, and multimodal formats through a single API.
