William Sankey

William Sankey runs Northspyre, the platform that today sits underneath more than $175 billion of real estate development. Office towers, museum wings, affordable housing, ground-up complexes. The decisions that move those budgets now run through software he started writing himself, alone, in the hours after his day job ended.

That is the part worth holding onto. Before Northspyre was a category, before the $32 million in venture money and the Series B, it was a side project. A project manager in New York, surrounded by some of the sharpest people in commercial real estate, watching them lose half their day to a tool invented for accountants in 1979.

Sankey did not come to technology through computer science. He came to it through frustration. As assistant to the project executive on the billion-dollar renovation of Madison Square Garden, he had a front-row seat to a strange contradiction: elite professionals, the best in the business, spending the bulk of their hours copying numbers between cells, rebuilding the same reports, and hunting for information that should have been one click away.

He moved between firms. Jones Lang LaSalle, where he learned the mechanics of project finance, cost management and vendor oversight. Macklowe Properties, overseeing renovations and condo conversions. Madison Realty Capital, as a senior project manager working debt and equity strategies. Different logos, different lobbies, identical guts.

So he taught himself to code. Not as a career pivot, at first, but as self-defense. He automated his own grunt work. The scripts got better. The side projects got more ambitious. One of them eventually looked enough like a product that it became the first Northspyre prototype. In 2017 he co-founded the company and, in doing so, helped name a category that had not existed before him: Real Estate Development Management.

The pitch is almost rude in its simplicity. Developers who adopt Northspyre, the company likes to say, might never open another spreadsheet. Instead of gut instinct and brittle formulas, the platform offers what Sankey calls proactive intelligence: automated data capture, real-time budgets, and forecasting that flags the effect of a change order before it detonates a timeline. It is subtractive technology. It removes the busywork rather than piling on more dashboards.

The first organization to bet on this was not a real estate behemoth. It was the Museum of Modern Art, which trusted a young, unproven company with its roughly $400 million expansion. For a startup pitching software to one of the most reputation-sensitive institutions in New York, it was the kind of validation money cannot buy. Other clients followed, and the dollar figure flowing through the system kept climbing past every round number until it crossed $175 billion.

Sankey's credentials read like a planner's dream. A bachelor's in architecture and urban studies from Yale. A master's in urban planning from Harvard's Graduate School of Design. A LEED AP Building Design + Construction certification. And yet the skill that actually built his company, software, is the one no professor handed him. He went and got it himself, on weekends, because the alternative was watching smart people waste their lives in cell B47.

What he wants from all of it is bigger than tidier budgets. Sankey talks about real estate as one of the most tech-averse industries on the planet and treats that as an opportunity rather than a complaint. He connects the dull mechanics of project delivery to the things people actually feel: less waste, more equity, fewer food deserts, better public transit, communities that hold together. Build faster and smarter, the logic goes, and you get to build more of what cities actually need.

It is a long way from a spreadsheet on a Garden renovation to a venture-backed platform with billions of dollars of projects running through it. But the throughline is consistent and a little stubborn: see the tedious thing, refuse to accept it, and write the code that makes it go away.
