Bret Taylor's Sierra acquires Fragment to expand AI customer service capabilities

Sierra, an AI startup founded by former Salesforce co-CEO Bret Taylor that automates customer service conversations, has acquired Fragment, a Y Combinator-backed French AI startup. The deal adds Fragment's technology to Sierra's platform for handling customer inquiries.

Fragment specializes in AI agents (software that makes decisions and takes actions without human intervention) trained on customer data, allowing businesses to automate responses to common questions. Sierra's acquisition lets them offer this capability to companies managing high volumes of customer support requests.

For business teams currently hiring customer service staff or juggling long support queues, this means access to AI tools that can handle routine questions independently—reducing hiring pressure while keeping experienced agents focused on complex issues that need human judgment.
