Antoni Rosinol and the problem of getting AI to work
Before co-founding StackAI, Antoni Rosinol taught robots to make sense of their surroundings. His next challenge was the office - and the tangled systems that keep it running.
StackAI Wants the Boring Work - and Knows When to Ask a Human
The enterprise agent builder turns documents, models, approvals, and business systems into visible workflows. It is built for the awkward stretch between a clever demo and software an audit committee might actually approve.

Tony (Antoni) Rosinol is the co-founder and CEO of StackAI, the no-code platform that lets enterprises build, deploy, and govern custom AI agents. An MIT PhD in computer vision and SLAM, he created the open-source Kimera robotics system before pivoting from teaching robots to see the world to teaching agents to run the back office. He started StackAI with fellow MIT PhD Bernard Aceituno out of Y Combinator's Winter 2023 batch, raised nearly $20M, and in May 2026 sold the company to Asana for $75M, where the founders now build toward an operating system for human-agent teams.
