Instinct: From Zero to $2.5B in 4 Months

23-year-old Noah Shinn's AI assistant just raised $250M Series B (Index Ventures + Benchmark co-leading), bringing total funding to $350M and valuation to $2.5B.

Timeline:
- Early August: Series A at $500M valuation (Kleiner Perkins, $75M)
- Late August: Series B at $2.5B valuation ($250M)
- Valuation jumped 5x in weeks

Why it matters:
Instinct went from unknown to viral by solving a real problem—automating email, calendar, and task management. The speed of capital deployment signals investor conviction in AI agents that handle daily work.

Key metric: 4-month-old startup commanding unicorn valuation.

Takeaway: Speed + product-market fit = capital velocity. Founders building AI agents for repetitive workflows have a narrow window to capture mindshare before consolidation.
