Sierra last week announced that they had reached $100 million in annual recurring revenue, seven quarters after launch. The company framed the number as evidence that AI agents are entering core enterprise workflows. It also said that more than half its customers generate over $1 billion in annual revenue.
The milestone confirms that large companies are now paying for agent-driven automation at scale. It does not confirm that the technology can operate reliably across the full range of customer interactions.
