Leadership Comments

“Residential real estate is still run across an enormous number of disconnected systems, datasets, and manual workflows,” said Dod Fraser, CEO and Co-Founder of Mainstay. “We have spent years building the technology to seamlessly connect data, decisions, and execution for the largest residential investors.

“Mainstay and Truelist are both unusual in that their teams have actually built and operated these systems at scale inside the industry’s largest and most innovative residential platforms,” said Clelia Peters, Managing Partner of Era Ventures and a Mainstay board member.

Market and Business Growth

Mainstay has facilitated more than $12 billion in real estate transactions and executed more than 2 million agentic workflows across over 50,000 external portals.

The company says it serves 95% of the 60 largest residential real estate investors.

Its platform supports workflows across buying, owning, and selling homes, while Truelist adds listing data and workflow capabilities for brokerages and agents.

What Happens Next?
