Enterprise AI Agents — Founded by Bret Taylor
The consensus on Sierra: in-person-first culture with elite founders and one of the fastest revenue ramps in enterprise SaaS history — strong equity at a $15B valuation, but expect a demanding pace.
Sierra is building enterprise AI agents, founded in 2023 by Bret Taylor (ex-Salesforce co-CEO) and Clay Bavor (ex-Google VP). The company crossed $100M ARR in roughly seven quarters and reported $150M+ ARR in early 2026, on the back of a $950M Series E that valued Sierra at $15B. The culture is in-person-first, engineering-driven, and fast-moving, with elite founders who have proven track records in building world-class products.
