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.

Fragment co-founders Olivier Moindrot and Guillaume Genthial will be joining the Sierra team.
