Artificial intelligence startup Sierra, co-founded by ex-Salesforce co-CEO Bret Taylor, is more than quadrupling its valuation to $4.5 billion in a fresh funding round.
The San Francisco-based company, which was valued at $1 billion in January, raised $175 million in a funding round led by Greenoaks Capital. The Information reported earlier this month that Sierra was in the midst of raising capital.
Taylor is chairman of OpenAI’s board and previously ran Salesforce, alongside Marc Benioff. He was also chairman of Twitter when Elon Musk was negotiating to buy the social media company. Taylor is a longtime entrepreneur, widely credited with helping to create Google Maps. At Google, he met his Sierra co-founder Clay Bavor, who spent nearly two decades at the tech giant, leading virtual reality efforts and Google Labs.
Sierra is focused on helping enterprises like home security company ADT, Sonos, Weight Watchers and Casper personalize and implement AI agents for customer service. Taylor and Bavor unveiled the startup earlier this year.
“We think every company in the world, whether it’s a technology company or a 150-year-old company like ADT, can benefit from AI, and the technology is ready right now,” Taylor told CNBC in an interview. “We want to enable Sierra to address that market, and that means expanding internationally and to other industries.”
ICONIQ and Josh Kushner’s Thrive Capital contributed to the new funding round.
Taylor describes Sierra as “conversational AI,” and bristles at the word “chatbot,” even banning the phrase in the company’s downtown San Francisco office. Sierra is looking to create a more conversational style of interaction, Taylor said. He pointed to the ease of OpenAI’s ChatGPT and compared it to the frustrating experience of talking on the phone with an airline bot.
“When you think of chatbots, you think of those annoying, robotic things — you can feel the difference,” Taylor said, adding that Sierra is making their agents more “empathetic and conversational.”
Sierra’s team lets each client customize the agent’s personality to its corporate brand. Clothing company Chubbies, for example, took a more sarcastic route with a younger sounding agent named Duncan Smothers. Taylor said some luxury brands are opting for a British accent with a more serious tone.
“We really think that your conversational AI agent should be not only transactional, but a brand ambassador,” Taylor said. “It’s actually something that is a statement of your values. So do you want to be sarcastic? Do you want to use emoji? Do you want it to sound like text messaging, or do you want it to sound like a lawyer?”
Sierra uses what Bavor and Taylor describe as a “constellation” of models, with a “supervisor.” The technology uses one model to do the heavy lifting, with the expectation that it won’t be 100% reliable, but use a second model as a backup, to “check” the others and help with accuracy. The company currently relies on large language models from OpenAI, Anthropic and Meta, among others.
There’s competition in the space. Taylor’s former company, Salesforce, as well as Microsoft, in partnership with OpenAI, are exploring the AI agent space. Taylor compared Sierra to the companies that built cloud software on top of Amazon Web Services and other cloud infrastructure.
“In the cloud era, you had Shopify, Salesforce, ServiceNow and Adobe — I think the same thing will play out in AI with Sierra,” Taylor said. “We’re helping their branded customer facing agent.”
He mentioned startups like Cursor, which makes coding agents, and Harvey, which makes legal agents.
Sierra’s funding follows a flurry of major AI announcements in Silicon Valley. OpenAI raised billions of dollars at a $157 billion valuation. Perplexity is in the midst of raising a round that values the company at $9 billion, a source confirmed to CNBC. One in three venture dollars this year has gone to an AI startup, according to CB Insights.
“When a technology wave like this happens, I think a lot of people are trying to place their bets,” Taylor said. “I don’t know which company will win, but it’s a smart investment, categorically. Clearly customer experience and customer service is a huge opportunity, and I think we are the leader in this space, and seeing a lot of demands because of that.”

The biggest banks are planning to sue the Federal Reserve over the annual bank stress tests, according to a person familiar with the matter. A lawsuit is expected this week and could come as soon as Tuesday morning, the person said.
The Fed’s stress test is an annual ritual that forces banks to maintain adequate cushions for bad loans and dictates the size of share repurchases and dividends.
After the market close on Monday, the Federal Reserve announced in a statement that it is looking to make changes to the bank stress tests and will be seeking public comment on what it calls “significant changes to improve the transparency of its bank stress tests and to reduce the volatility of resulting capital buffer requirements.”
The Fed said it made the determination to change the tests because of “the evolving legal landscape,” pointing to changes in administrative laws in recent years. It didn’t outline any specific changes to the framework of the annual stress tests.
While the big banks will likely view the changes as a win, it may be too little too late.
Also, the changes may not go far enough to satisfy the banks’ concerns about onerous capital requirements. “These proposed changes are not designed to materially affect overall capital requirements, according to the Fed.
The CEO of BPI (Bank Policy Institute), Greg Baer, which represents big banks like JPMorgan, Citigroup and Goldman Sachs, welcomed the Fed announcement, saying in a statement “The Board’s announcement today is a first step towards transparency and accountability.”
However, Baer also hinted at further action: “We are reviewing it closely and considering additional options to ensure timely reforms that are both good law and good policy.”
Groups like the BPI and the American Bankers Association have raised concerns about the stress test process in the past, claiming that it is opaque, and has resulted in higher capital rules that hurt bank lending and economic growth.
In July, the groups accused the Fed of being in violation of the Administrative Procedure Act, because it didn’t seek public comment on its stress scenarios and kept supervisory models secret.
