If the ultra-luxury real estate scene has taught us anything lately, it’s that the most interesting homes aren’t always the ones you see marketed online. They’re the ones you hear about quietly—shared through trusted networks and floated privately among top brokers.

As whisper listings become more common, discretion has turned into a form of value. Pacaso, best known for popularizing high-end co-ownership, is tapping into that mindset with Infinity, a new invitation-only exchange that allows owners of exceptional vacation homes to swap stays discreetly, without having to expose their hideaways to the general public.

This is not Airbnb, where just anyone can peruse the options and book a stay; it is far more a private members club where birds of a certain feather can more effectively control exactly who gains access to their prized hideaways. Infinity is built for people who own $5 million to $20 million homes in places like St. Barts, Tuscany, Paris, or New York, who are understandably selective about who gets the keys. Every homeowner and every residence is thoroughly vetted, and everything happens behind the scenes, with no public exposure and without the hoi polloi cycling through the photos.

“Most people think of a second home as a place you love—but one that also locks you into a single destination,” Pacaso CEO and co-founder Austin Allison tells Robb Report. “Infinity flips that. Your home becomes a passport into a private network of equally exceptional places around the world.”

The $100,000 one-time initiation fee grants members 10 years of access to the Infinity network, allowing them to temporarily trade homes with other members. Pacaso manages everything, with scheduling and other logistics handled through the company’s proprietary platform, removing the friction—and the trust gap—that often comes with private exchanges. The goal is to arrive knowing the borrowed getaway will be of the same quality and maintained to the same high level as your own home.

Infinity builds on Pacaso’s recent expansion into the luxury marketplace. In 2024, the company introduced its Estate Collection—its most design-forward, high-touch homes—aimed at buyers who wanted the benefits of co-ownership without compromising on architecture, amenities, or location. Infinity takes that same sensibility and applies it to whole-home owners, extending Pacaso’s reach beyond shared ownership and into the growing universe of off-market access.

The current roster of top-tier destinations includes St. Barts, the British Virgin Islands, Tuscany, Mexico City, Ibiza, Carayes, Paris, Verbier, New York City, and California’s Napa Valley, with more being added on a weekly basis. Membership will be capped, according to a Pacaso spokesperson, though the company hasn’t said where that ceiling will land.
