5 Go-to-Market Lessons from Northspyre’s Journey to Category Leadership

When William Sankey appeared on a recent episode of Category Visionaries, his story revealed a masterclass in building vertical SaaS. As Northspyre grew from a bootstrapped startup to managing over $125 billion in real estate projects, their journey offers valuable lessons for founders targeting traditional industries.

1. Domain Expertise as a Competitive Moat Most startups target industries from the outside, but Northspyre’s success stems from deep industry knowledge. William spent years in real estate development before building Northspyre, giving him unique insight into the market’s pain points: “these people are the very best at what they do… but they spend a lot of their time doing a lot of tedious administrative work.”

This expertise remains central to their DNA: “we always try to hire a lot of real estate professionals… we have quite a few people on our staff that have actual hands-on experience running and delivering projects. They really get it. They haven’t just done a few user interviews.”

2. Bootstrap to Product-Market Fit Instead of immediately raising capital, Northspyre stayed lean while validating their market. William recalls their early days: “we sort of reached a point where we sort of built a lot of core functionality. We listened a lot to the MoMA and some other customers we picked up along the way.” This patient approach led to explosive growth in 2019 when they hit product-market fit.
3. Land an Anchor Customer Their breakthrough came from landing the Museum of Modern Art as their first customer for a $400 million expansion project. Rather than trying to sell to everyone, they focused on proving their value with a prestigious anchor client. The museum’s real estate director told them, “I was just getting ready to hire a couple of people because this project is pretty massive… but you know what? I’ll give this a shot.”
4. Ignore Early Skepticism Despite being “ejected twice by Y Combinator,” Northspyre stayed convicted in their vision. William notes this was “back before it was obvious that vertical SaaS was going to exist in every major industry.” Rather than pivoting to a more “venture-friendly” approach, they stayed focused on solving real industry problems.
5. Layer in Network Effects Instead of stopping at workflow automation, Northspyre is building network effects through data. As William explains: “just two days ago, we unveiled a new product, where we combed across $125 billion of project data. And now we’re not only helping to execute on projects, but we’re giving you market data into what things might cost in different markets.”

This evolution addresses both “execution error” and helping customers “make the right assumptions because the other reason is the budget was wrong to start with.” Each new customer now makes the platform more valuable for everyone.

Build for Long-term Category Leadership Rather than focusing on quick wins, Northspyre is playing a longer game. William hints at their ambitions: “hopefully five years from now, wow, didn’t see that coming from Northspyre. I thought they just sold software.”

For founders targeting traditional industries, Northspyre’s journey offers a powerful template: combine deep domain expertise with modern technology, stay patient through initial skepticism, and continually expand value through network effects. While it might not be the fastest path to growth, it builds the foundation for category leadership in massive markets.

The results speak for themselves. From their New York origins, Northspyre now operates “in every major city across the US. And a lot of secondary and tertiary markets, whether we’re building projects in Montana and Iowa, all over the country.” Their success shows that sometimes the best disruption comes from within.
