PyTorch engineers just built a $4B AI infrastructure empire Fireworks AI closed $250M Series C at $4B valuation. Powers AI apps for Uber, Shopify, Genspark. • $250M led by Lightspeed, Index Ventures • 12x faster than vLLM, 40x faster than GPT-4 • 140B tokens daily, 99.99% uptime • 10,000+ enterprise customers How it happened: • PyTorch core team left to build specialized inference • Built proprietary serverless infrastructure • Focused on open-source vs closed APIs • Secured enterprises through superior speed/cost • Scaled to 10 trillion tokens daily by 2025 Takeaway: Deep technical expertise + enterprise focus = infrastructure moats hyperscalers can't replicate.
