Filipe Castro Matos is an Entrepreneur-in-Residence at Altar.io, where he helps founders go from idea to MVP with clarity and speed. With over a decade of experience across B2C and B2B startups—including an early exit, viral growth experiments, and advising dozens of founders—Filipe specializes in helping teams find their first customers and build Go-to-Market strategies that actually work. 

His work today centers on solving one of the biggest problems in early-stage startups: the gap between building and growing. He's quietly building something new to bridge that gap.
