Marketplace for buying and owning a fraction of a premium vacation home, managed as a shared LLC with professional property management.
Pacaso is a San Francisco-based real estate technology company that enables individuals to buy fractional ownership stakes in premium vacation homes, making second-home ownership accessible to a broader range of buyers. Buyers purchase one-eighth to one-half ownership shares in premium homes in desirable vacation destinations including Napa, Park City, Aspen, and Lake Tahoe, with each home structured as a professionally managed LLC. Pacaso handles all property management, maintenance, scheduling, and coordination among co-owners, removing the typical friction of shared ownership. The company uses a proprietary smart-scheduling algorithm to fairly allocate usage time among co-owners based on their ownership share. Pacaso was founded in 2020 by former Zillow CEO Spencer Rascoff and has raised over $1.5B in equity and debt capital from investors including SoftBank, GV, and Greycroft. The company facilitates significant transaction volumes and has faced some community opposition in vacation destination markets concerned about second-home density. It competes with Ember and Arrived Homes in the fractional vacation property market.

a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
