Bret Taylor’s Sierra buys YC-backed AI startup Fragment

Sierra, the customer service agent startup founded by Bret Taylor, announced on Thursday that it has acquired the YC-backed French startup Fragment, which helps businesses integrate AI into workflows.

This is Sierra’s third public acquisition. It previously bought Japan-based enterprise AI solutions company Opera Tech (which it acquired in late March) and voice agent company Receptive AI (which it also announced it acquired in late March). Fragment co-founders Olivier Moindrot and Guillaume Genthial will be joining the Sierra team.

In a blog post, Taylor and his co-founder, Clay Bavor, wrote that Moindrot and Genthial will bring “valuable strength” to Sierra’s “agent development efforts in France.” Terms of the deal were not announced. PitchBook estimates that Fragment raised around $2 million through its seed round.
