Sierra has raised US$950 million from new and existing investors, led by Tiger Global and GV, at a valuation of over US$15 billion.
Sierra now has more than US$1 billion to invest in becoming the global standard for companies wanting to transform their customer experiences with AI.
According to Sierra co-founders Brett Taylor and Clay Bavor, the company is in the very early stages of AI adoption.
“Agents have enabled us to digitize the last remaining analog channel: the telephone. All of us can now get things done without waiting on hold, in any language, and at any time of day,” they said.
They added that AI agents are different from what came before because they are personal, proactive, and act independently — serving each of your customers individually, and optimizing for their happiness and your business goals.
“Rather than building agents to have one and done conversations, you’ll build agents that manage relationships — anticipating your customers’ needs, resolving issues, and driving outcomes like sales, retention, and loyalty,” they added.
