Intro
In June 2025, Runwise, a New York–based smart building platform, raised $55 million in Series B, led by Menlo Ventures, with participation from MassMutual Ventures, Nuveen Real Estate, Multiplier Capital, Munich Re Ventures, and returning investor Fifth Wall. The company’s total funding now stands at approximately $79 million, positioning it for a nationwide expansion of its AI-driven platform.

Founded in 2010, Runwise offers a vertically integrated operating system—wireless hardware, cloud-based AI, and controls—that optimizes heating, cooling, electric, and water systems in buildings. Installed in a day, retrofit-friendly, and delivering real-time energy control and savings.
The platform is deployed in over 10,000 buildings across the U.S., serving over 1,000 clients including Related, Equity Residential, and National Grid.
Who It’s Best For
Ideal for real estate owners and operators managing aging portfolios who want immediate energy savings, improved tenant comfort, and emissions reduction—without costly renovations.
