AI Startup

An AI startup is a company built around AI as a core product or capability. The category exploded after ChatGPT's November 2022 launch and remains the largest startup category by funding through 2026. Anthropic ($200B), OpenAI ($500B), xAI ($80B), Mistral ($30B), Hugging Face ($5B), Cognition ($4B), Cursor ($2.5B), Perplexity ($9B), Glean ($7B), Decagon ($1.5B) — these are some of the heaviest-funded private AI companies in 2026. AI startup valuations are aggressive and assume continued AI growth; the bear case is concentration in a handful of customers and rapidly-eating-margins from open-source.
