Decagon

Decagon provides AI-powered customer support agents that replace the entire support function rather than add a copilot. Founders conducted ~100 customer conversations before building product, then scaled from 0 to 8-figure ARR in 18 months. In 2025 alone signed 100+ new enterprise customers across travel, finance, health, and retail, and tripled valuation to $4.5 billion in under six months.
