Sierra builds a conversational AI platform that enables companies to create AI agents capable of answering questions, taking action, reasoning through complex problems, and delivering personalized service. The platform operates across multiple channels - chat, SMS, WhatsApp, email, voice, and beyond - allowing businesses to deploy sophisticated AI systems without building from scratch.
Founded in 2023 by Bret Taylor and Clay Bavor, the company brings together deep expertise in technology leadership. Taylor previously served as co-CEO of Salesforce and CTO of Facebook, while Bavor spent 18 years at Google, leading Google Labs, Google Lens, and the company's AR/VR efforts. Both founders first met at Google before starting Sierra.
The platform has quickly attracted major brand partnerships including WeightWatchers, SiriusXM, Sonos, and OluKai, spanning customer experience, media and entertainment, consumer electronics, and retail. Sierra operates from San Francisco with offices in New York, Atlanta, London, Singapore, and France, serving customers and talent globally.
