Sierra
Founded by former Salesforce co-CEO Bret Taylor and reportedly at $200M ARR in 2026, Sierra's outcome-based pricing is a genuinely different model worth understanding, but it still requires a custom enterprise contract with no visible price floor.
What it does
Sierra builds AI customer service agents for large enterprises, handling conversations across chat, voice, and messaging channels with the goal of fully resolving customer issues rather than just routing them. Named customers include Rocket Mortgage, SiriusXM, Brex, Redfin, and SoFi. Its pricing model charges per successful autonomous resolution (reported around $1.50 per resolved conversation) rather than per seat or per platform license, with escalations to human agents handled at no additional charge — an approach the company has publicly framed as more aligned with the value delivered.
Who this helps
