Description
Short Intro: Stack AI is a proprietary enterprise AI workflow platform founded in 2022 by MIT PhDs Antoni Rosinol (CTO) and Bernardo Aceituno (CEO), alongside co-founder Melissa Forstell, through Y Combinator. The company raised a $16M Series A in May 2025 from Lobby VC and LifeX Ventures, with personal backing from Vercel CEO Guillermo Rauch and Weaviate CEO Bob Van Luijt, bringing confirmed funding to $19.5M. Stack AI deliberately exited the SMB market to focus entirely on regulated enterprise sectors — its customers include a top-five US defense agency, Nubank, and MIT Sloan, with over 90,000 users having created more than 100,000 AI agents on the platform.
