Runwise—the leading smart operating system for buildings—today announced a $55M Series B financing round. The round was led by Menlo Ventures—a leading venture capital firm investing at the forefront of AI—with meaningful participation from new investors MassMutual Ventures, Nuveen Real Estate, Multiplier Capital, and Munich Re Ventures, alongside returning backers Soma Capital, Alumni Ventures, Helium-3, Cooley, and Fifth Wall. The fresh capital will support product innovation, team expansion, as well as entry into new core markets. The raise brings Runwise’s total funding to $79M.
“Most buildings—old and new—still run on 1960s technology, wasting billions of dollars, making living and working in cities less safe and comfortable, and generating massive amounts of CO2,” shared Jeff Carleton, Chief Executive Officer & Co-Founder, Runwise.”Every building needs to be rebuilt with software, not bricks. That’s what we’re doing at Runwise, transforming outdated infrastructure into intelligent systems that can be installed in a day, paid back in months, and scaled across entire portfolios, said Lee Hoffman, President & Co-Founder, Runwise. “This round gives us the fuel to accelerate that mission and become the global default for the real estate industry,” added Mike Cook, Chief Growth Officer & Co-Founder, Runwise.
“Runwise delivers exactly what building operators need: real savings and simplicity,” stated John Skipper, Director of Energy Management at First Service Residential. “More than 150 of our buildings have installed Runwise, and in most buildings we have seen up to 30% in energy savings, while making the buildings more comfortable, and easier to manage. It’s a win for affordability, a win for operations, and a win for the environment.”
Runwise is the most capitalized and widely deployed smart building platform in the U.S., setting a new standard for how smart buildings operate, proving that the future of infrastructure runs on software.

BuiltAPI GmbH, the company pioneering API-driven data infrastructure for real estate investment and asset management, has successfully closed its latest funding round backed by industry leaders including Second Century Ventures, TDS, and Propertymark. The investment marks a major milestone as BuiltAPI expands its services across Europe and the UK, following its graduation from the REACH UK Accelerator Program.
BuiltAPI tackles one of the real estate sector’s most persistent problems: fragmented, siloed data ecosystems. The company provides a robust API framework that enables seamless connectivity between legacy systems, modern SaaS tools, and intelligent automation platforms — with interoperability, governance, and cybersecurity at its core.
“We’re building the backbone of real estate data infrastructure,” said Olga Dentzel, Co-Founder of BuiltAPI. “This funding and the support of the REACH UK program are accelerating our ability to deliver secure, scalable integrations to clients across borders.”
BuiltAPI’s technology is already making an impact with major real estate institutions such as HIH Real Estate and its fund service platform INTREAL, through their digital unit INTREAL Solutions. These collaborations highlight a shared vision for practical and scalable digital transformation in real estate asset and investment management.
“The industry doesn’t need yet another tool — it needs a connective tissue,” added Ivan Nokhrin, Co-Founder of BuiltAPI. “Our mission is to empower real estate professionals to access, share, and act on their data securely and without barriers.”
Graduation from the REACH UK Accelerator — the scale-up program backed by Second Century Ventures – marks BuiltAPI’s official entry into the UK market. The program has played a key role in unlocking investors support and refining BuildAPI’s growth trajectory.
