Sierra, the AI agent startup founded by Bret Taylor, is reportedly close to raising hundreds of millions of dollars in a funding round led by Greenoaks Capital, which would value the company at over $4 billion. Sierra, which previously raised $100 million last year and $1 billion earlier this year, develops conversational AI agents capable of engaging with customers using service-specific context.
