About Portoro
Portoro is a premium short-term rental operator managing over 600 properties across some of the most desirable—and competitive—vacation destinations in the U.S., from coastal Florida to upstate New York. Portoro’s commitment to excellence is evident in their comprehensive service offerings, including a homeowner-dedicated portal providing transparent information and exceptional support, in-home intuitive technology ensuring properties are well-equipped for guests, and dedicated local teams available 24/7 to assist with any needs.
With a revenue team focused on scaling acquisitions efficiently, Portoro’s Director of Revenue Management, Donna Sluijter, needed an asset intelligence platform that could match the speed and complexity needed to grow their rapidly-expanding short-term rental (STR) portfolio.
The Challenge
Portoro’s high-touch model depends on more than great guest experiences—it runs on owner trust. And that trust begins with accurate, data-backed revenue projections. These short-term rental revenue projections are foundational: they shape owner expectations from day one, guide Portoro’s acquisition strategy, and power long-term business growth.
However, each region in their portfolio brought its own complexities when building projections: fluctuating demand patterns, hyper-local seasonality, and competitive dynamics that made one-size-fits-all projections nearly impossible.
Worse, their existing tools often missed the mark. Donna and her team had relied on AirDNA, only to find that the projections were frequently inflated and lacked the granularity to reflect reality on the ground. Without accurate forecasts, Portoro risked overpromising to owners and underdelivering on performance—a recipe for churn in a business built on trust.
“We were lacking Airbnb market data at a granular, customizable level. AirDNA estimates were always way inflated.” – Donna Sluijter, Director of Revenue Management
Portoro needed a platform that could support honest, data-backed forecasting—one that would empower their team to deliver accurate numbers owners could count on. That’s when they turned to SummerOS.
The Solution
With SummerOS, Portoro found an asset intelligence platform built for scale, speed, and accuracy. It empowers them to create custom market sets based on real, comparable listings—enabling true like-to-like projections across their diverse portfolio.
Instead of relying on static market-level reports or generalized data, they now build hyper-local STR competitive sets tailored to specific property types, amenities, and performance tiers, and do it fast. SummerOS also supports weekly market benchmarking reports for Portoro’s leadership team, enabling smarter strategic decisions grounded in real-time Airbnb performance data.
