Matt McDonnell on Investing in the Future of the Built Environment
Real estate is the largest asset class in the world – larger than public equities and most national economies – yet much of it still runs on spreadsheets, manual workflows, and decades-old systems.
For Matt McDonnell, co-founder and managing partner of Stellifi Ventures, that gap isn’t just inefficient. It’s the opportunity.
In a recent appearance on the AI Interconnect Podcast, Matt shared how artificial intelligence, automation, and next-generation PropTech startups are reshaping the way buildings are financed, operated, and maintained – and why the biggest opportunities in real estate technology aren’t flashy consumer apps, but the foundational infrastructure quietly powering the built environment.
His core belief is simple: the future of real estate will be driven by better data, smarter workflows, and AI-native tools that make operations dramatically more efficient. And we’re still early.
An unconventional path into venture capital
Matt’s route into venture capital didn’t begin in finance or tech. It began at sea.
Before business school, law school, and startups, he spent years leading leadership and character development programs aboard traditional sailing ships with Outward Bound. Life on small crews in unpredictable environments meant solving problems collaboratively, quickly, and without the luxury of walking away.
That experience turned out to be surprisingly relevant to startups.
Early-stage companies, like boats offshore, operate with small teams, limited resources, and constant uncertainty. You adapt or you sink. The experience shaped how Matt thinks about founders today: resilience, clarity under pressure, and teamwork matter just as much as strategy.
After operating roles in venture-backed startups, launching a family office, and working directly in real estate development, he began to notice something striking. Compared to nearly every other major industry, real estate lagged dramatically in digital transformation.
While fintech, logistics, and healthcare were modernizing rapidly, property owners and operators were still relying on fragmented systems and manual processes.
That inefficiency pointed to a massive, underbuilt market.

Why Stellifi Ventures focuses on PropTech
At Stellifi Ventures, Matt and his partners focus exclusively on PropTech and real estate infrastructure startups. Their strategy centers on backing early-stage founders building the core systems that make real estate work better.
The reasoning is structural.
In consumer software, success often means capturing small percentages of a huge market. But real estate behaves differently. When large owners and operators adopt technology that truly improves performance, adoption tends to spread quickly across entire portfolios or even entire segments of the industry.
If you get it right, you don’t win a sliver of the market — you can become the standard.
Rather than chasing surface-level features, Stellifi looks for companies improving the underlying “plumbing” of real estate: operations software, data infrastructure, payments, insurance, underwriting, and workflow automation. These foundational layers, Matt believes, will define the next decade of real estate innovation.
Where AI is already changing real estate
Artificial intelligence has accelerated this transformation.
Instead of treating AI as a buzzword, Matt sees it as a practical tool for eliminating some of the most labor-intensive processes in the industry. Historically, real estate has relied on armies of analysts building Excel models, asset managers stitching together disconnected data, and property teams manually handling tenant communication and maintenance requests.
AI changes the economics of that work.
Financial modeling, reporting, and underwriting can be automated. Data from multiple systems can be unified and synthesized instantly. Tenant communication and service requests can be handled around the clock without adding headcount. One analyst can now accomplish what previously required a full team.
The result isn’t just lower costs — it’s better decisions and faster operations.
Over the next 12 to 24 months, Matt expects AI in real estate to have the greatest impact at the operational layer, where high-volume, repetitive tasks and messy data create obvious opportunities for automation and efficiency gains.
The overlooked opportunities most founders miss
One of the most interesting insights Matt shared is that the best opportunities in PropTech often look surprisingly unglamorous.
Real estate still runs on countless manual processes that most technologists never see. For example, many software vendors selling into multifamily portfolios still receive hundreds of physical checks each month because each property operates as its own legal entity. Payments, collections, and reconciliations remain painfully manual. Insurance underwriting often lacks real-time visibility into asset performance. Critical information sits across disconnected systems that don’t communicate with each other.
These aren’t flashy startup ideas. But solving them creates enormous leverage.
Matt sees growing opportunity where fintech, insuretech, and real estate operations converge, especially around payments infrastructure, insurance intelligence, and unified data models. These second-order problems, exposed once the first wave of software is adopted, may define the next generation of category leaders.

What Stellifi looks for in founders
Over time, Matt has developed a clear view of what makes a strong PropTech founder.
The most compelling teams typically have deep domain experience. They’ve worked inside the industry and felt the pain firsthand. That lived experience helps them build better products and speak the language of their customers.
Conviction matters too. Startups inevitably hit obstacles, pivots, and existential moments. Founders who truly understand the problem are more likely to persist and adapt.
Capital efficiency is another key factor. In PropTech, the bar for product reliability is high, which can tempt teams to overspend early. But in today’s funding environment, disciplined growth and thoughtful distribution strategies are critical. Traction and product-market fit still matter more than aggressive burn.
Adapting faster in a tougher market
One lesson Matt has internalized over the past few years is that markets don’t always rebound as quickly as expected.
Higher interest rates, rising costs, and slower development cycles have created sustained pressure across real estate. Waiting for conditions to improve isn’t a strategy.
The companies that succeed adapt faster. They rethink distribution, refine pricing, and pivot when necessary rather than assuming the environment will return to the past.
Speed and flexibility, more than patience, have become the defining traits of resilient startups.
Building the future of the built environment
At its core, Matt sees Stellifi’s work as bigger than venture investing.
It’s about modernizing the infrastructure of the built world.
Real estate has operated largely the same way for generations. Now, with AI, automation, and unified data platforms, the industry finally has the tools to evolve. The founders Stellifi backs aren’t just building apps — they’re laying the technological foundation for how real estate will operate over the next several decades.
For operators, investors, and entrepreneurs alike, the opportunity is enormous.
And we’re just getting started.
