Companies that use Fireworks AI

Source: Analysis of Linkedin bios of 349 companies that use Fireworks AI

I noticed that Fireworks AI's customers are predominantly building AI-powered products and platforms themselves. These aren't companies just using AI, they're selling it. I see AI labs like Anysphere (Cursor) and Reflection, developer platforms like Vercel and Airtable, conversational AI companies like Gupshup and Skit.ai, and numerous vertical AI solutions for legal (Harvey), healthcare (Heidi), finance (Hebbia, Rogo), and customer service. Many are embedding generative AI directly into their core products or building autonomous agents.

These companies span the full spectrum but lean heavily toward high-growth ventures. I see substantial Series B through Series F rounds (Workato's $200M, Cribl's $200M, Harvey's $59M recently), public companies like MongoDB and UiPath, and well-funded unicorns like Anysphere ($900M Series C). However, I also notice emerging players with 50-200 employees still in early funding stages. The common thread is ambition at scale, whether they're already serving Fortune 500 clients or racing to get there.
