The company emerged from the Built.io platform in 2018 and, according to press reports, was founded by Neha Sampat, Nishant Patel and Matthew Baier. Alongside the CMS, its lineup includes Launch for hosting websites, Personalize and Lytics for personalization, and Brand Kit for AI-written copy. Agent OS brings the AI features together and, according to the pricing page, is part of every plan.
