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. ” Terms of the deal were not announced. PitchBook estimates that Fragment raised around $2 million through its seed round.
Taylor, who also serves as OpenAI’s chairman of the board, co-founded Sierra alongside Google alum Bavor after stepping down as co-CEO of Salesforce in early 2023. The startup claims Casper, Clear, and Brex as customers and has raised more than $630 million in funding to date, from investors including Sequoia and Benchmark, giving it a $10 billion valuation.
