Sierra

Bret Taylor's enterprise voice-and-chat AI agent platform.

By Sierra (Bret Taylor) · Founded 2023 · San Francisco, CA · private

Sierra is the enterprise AI agent platform founded by Bret Taylor (former Salesforce co-CEO and OpenAI board chair) and Clay Bavor in 2023, last valued $4.5B+ (2024). The product is a voice-and-chat AI agent platform for large enterprise consumer brands (Sonos, ADT, WeightWatchers reportedly). Strengths: founder pedigree (Bret Taylor), aggressive enterprise sales motion, voice + chat both native, and AI agent capabilities competitive with Intercom Fin. Best fit for large enterprise consumer brands wanting AI-first customer support. Trade-offs: enterprise-only sales motion (no SMB/mid-market product), pricing meaningful (call-for-quote, reported $200K-$2M+/year), and category is genuinely new, methodology and stability still maturing.
