Built by people who have
run these buildings.

Mubarek Hassen

Mubarek spent ten years in commercial real estate development and operations before founding Piassa, building and managing data centers, tech labs, and hospitals for the most demanding owners in the world. He managed Google's real estate portfolio at CBRE, Apple's at Lincoln Property Company, and built the UCSF Mission Bay medical campus with DPR Construction.

He started Piassa because he watched the same problem repeat at every scale: the knowledge it takes to run a building well lives in scattered PDFs, disconnected systems, and the heads of the longest-tenured engineers. Piassa turns that fragmented record into intelligence owners can act on.
