What the source supports
Stripe’s customer story says that within a year of implementing Billing, Retell AI scaled from $1 million to $10+ million in annualized revenue and processes more than 30 million calls per month. Todd Li, president, is quoted on usage-based billing. The story calls Retell a 16-person company and says it bills by call minutes, LLM model, voice engine, and telephony. It does not name one model, so none is filled in.
The page does not show a publication date. 29 Oct 2026 is the day this file was checked, not the day Stripe published the story. The range is the company’s account as Stripe printed it. Stripe hosting the story is not the same as a processor feed of Retell’s books, so this row is not payment-checked.
