Sierra AI Raises $950M at $15.8B Valuation to Lead Enterprise AI Agent Race
$15.8B Valuation, 58% Up in Eight Months
Sierra, the AI customer agent platform, raised a $950M Series E led by Tiger Global and GV (Google's venture arm) on May 4, at a post-money valuation of $15.8 billion — up 58% from the $10 billion valuation set just eight months ago. Benchmark, Sequoia, and Greenoaks also participated.
The company grew ARR from $100M in late November 2025 to $150M by early February 2026 — a 50% jump in three months — underscoring the explosive enterprise demand for AI agents.
An Android Strategy for Enterprise AI
Sierra was co-founded by Bret Taylor, who chairs OpenAI's board and was previously co-CEO of Salesforce, and Clay Bavor, who led Google Labs and Google's VR efforts. Rather than positioning Sierra as a point solution for customer support, Taylor's vision is a platform role analogous to Android: licensing Sierra's AI to other companies building enterprise agent products, creating a broad ecosystem rather than a single vertical application.
The fresh capital will go toward international expansion and deepening Sierra's platform capabilities.
