Sierra, a startup based in San Francisco and specializing in developing AI agents for customer service in enterprises, made a significant announcement on Friday. The company revealed that it had achieved a remarkable milestone of reaching $100 million in annual revenue run rate (ARR). This rapid growth indicates a growing acceptance of AI agents across various industries.
The remarkable growth of Sierra took even its experienced co-founders, former Salesforce co-CEO Bret Taylor and long-time Google executive Clay Bavor, by surprise. In a blog post, they expressed their astonishment at the speed of their success, stating, “That’s a heck of a lot quicker than we expected.”
Sierra’s client roster includes prominent tech companies such as Deliveroo, Discord, Ramp, Rivian, SoFi, and Tubi, as well as established businesses outside the tech sector like ADT, Bissell, Vans, Cigna, and SiriusXM.
While Taylor and Bavor anticipated that tech firms would adopt AI customer service agents, they were amazed to see traditional businesses also embracing Sierra’s solutions.
The company boasts the ability to develop AI agents capable of handling tasks such as verifying patients for healthcare providers, processing returns, facilitating credit card replacements, and assisting customers with mortgage applications. This automation of customer service tasks that previously required human intervention has been a game-changer for Sierra.
Despite facing competition from startups like Decagon and Intercom, Sierra asserts its position as the leader in the AI customer service sector.
Following a $350 million funding round led by Greenoaks Capital in September, Sierra was valued at $10 billion. Other notable investors in the company include Sequoia, Benchmark, ICONIQ, and Thrive Capital.

With a $100 million ARR, Sierra currently holds a valuation at a 100x revenue multiple, showcasing strong growth despite the high valuation.
Sierra operates on an outcomes-based pricing model, where customers are billed for completed tasks rather than flat subscription fees.
Taylor and Bavor’s professional journey began at Google in 2005, where Taylor recruited Bavor as an associate product manager.
A graduate of Stanford with a background in computer science, Taylor co-developed Google Maps before founding FriendFeed, which was later acquired by Facebook. During his tenure at Facebook, he played a key role in the creation of the iconic “Like” button. His subsequent venture, Quip, a competitor of Google Docs, was acquired by Salesforce for $750 million in 2016.
After serving as Salesforce co-CEO alongside Marc Benioff for over a year, Taylor departed the company in 2023. Subsequently, Bavor, who had led products like Gmail and Google Drive during his 18-year tenure at Google, proposed the idea of starting Sierra during a lunch meeting with Taylor.
