Investors are clearly bullish about AI agent startup Sierra, former Salesforce Co-CEO Bret Taylor.
Sierra, which helps businesses build customer service AI agents, announced on Thursday that it had announced its $350 million in funding. The round, led by former investor Greenoaks Capital, values the startup at $10 billion, according to a company’s blog post that confirmed a previous report from Axios on Wednesday.
Sierra was founded in early 2024 by Taylor and long-time Google alum Clay Babon. The company claims it has landed hundreds of customers in its 18-month operation, including Sophie, Lamp and Brex.
Sierra has now raised $635 million fully, including the $110 million that was closed last February, led by Sequoia and Benchmark, and the $175 million round that was closed last October, led by Greenoaks.
Other investors include Iconiq and Thrive Capital.
As TechCrunch previously reported, Taylor and Bavor have a long history in customer service technology. Taylor spent nearly a decade at Salesforce and founded Quip a few years ago, which Salesforce purchased for $750 million in the summer of 2016.
Taylor met Bavor while he was on Google. He worked for several years before serving as Facebook CTO. Google has widely acknowledged that Taylor helped launch Google Maps. A few years later, he oversaw a Twitter board where Elon Musk acquires the social media site.

In fact, Taylor announced earlier this week that Sierra would begin its second year of its so-called APX program. This is a recent technical alumni turn opportunity that directly reflects the Google program that launched both Taylor and co-founder Clay Babon 20 years ago.
In particular, recruitment announcements stand out in what has become an increasingly demanding job market as companies assess the power of AI technologies like Sierra sells and the potential impact on the needs of the workforce.
The programme says it targets computer science alumni and offers both agent engineering and product management experience. Taylor explained that he offers what he calls “irresponsibility for liability” — as well as the freedom he and Bavor had on Google — to build and launch products – and are expected to tackle multiple product launches in their first year.
