Mainstay is the system of intelligence for residential real estate.
Buying, owning, and selling homes still happens across disconnected systems, fragmented data, and manual processes.
Mainstay brings it all into one platform. Connecting data, decisions, and execution. Every workflow feeds the next. Every transaction improves the system.
The hardest data problem in real estate.
Every home touches hundreds of disconnected systems. MLS listings, county records, HOA documents, tax assessments, permits, utilities, and neighborhood data. The same property can show different square footage depending on where you look. Mainstay stitches all of it together, continuously, across 0 homes. So every decision you make starts with data you can actually trust.
Built by operators who've lived the complexity of residential real estate.
