Who Owns ZO?

Tishman Speyer launched ZO in 2018 as a proprietary tenant amenities platform. The launch coincided with growing competition in the commercial office market, where landlords were increasingly differentiating their properties through amenities and services rather than location alone. The platform was initially deployed at Tishman Speyer properties in New York City, including the Rockefeller Center complex.

The ZO platform was designed to extend the workplace beyond the four walls of a tenant's leased office space. Core components included ZO Clubhouse lounges, which provide shared amenity spaces for tenants to gather, work, and socialize; ZO Fit fitness centers, offering expanded gym facilities; Studio Gather conferencing, providing meeting and event spaces; and ZO Assist, an administrative support service with receptionists and administrative staff.

The ZO mobile app connects tenants to the platform's spaces, events, and services. Through the app, members can access programming, building updates, neighborhood information, dining options, and convenient services. The app provides 24/7 access to ZO amenities and experiences.

Through the late 2010s and early 2020s, Tishman Speyer expanded ZO to properties in Boston, Chicago, Los Angeles, and other major US cities. The platform also extended to international properties in London, Paris, and Berlin. Each ZO Clubhouse is designed specifically for its building, with design-forward lounge areas, event spaces, and conference facilities tailored to the local tenant base.

In 2024 and 2025, Tishman Speyer continued to invest in ZO as part of building repositioning efforts. At 125 High Street in Boston, the firm added a ZO Clubhouse with a landscaped rooftop overlooking the Seaport, an expanded ZO Fit gym, Studio Gather conferencing, on-site wellness partners, and a golf simulator near the central atrium. The amenity-focused overhaul resulted in approximately 150,000 square feet of renewed and expanded leases, pushing the campus to roughly 82 percent occupancy by July 2026.

At 30 Rockefeller Center in New York, Tishman Speyer reported the building was 100 percent leased as of January 2026, despite the pending departure of Deloitte, the building's largest tenant, which will leave 430,000 square feet in late 2028. The ZO program, including access to a clubhouse lounge at nearby 1 Rockefeller Plaza, retail discounts, and restaurant reservations, was cited as a factor in attracting new tenants.

At 6 Grand Central in New York, Tishman Speyer opened a ZO Clubhouse with curated programming, inspired lounge spaces, and 24/7 access to services. The building also features a renovated lobby and direct access to Grand Central Station. At 525 West Monroe Street in Chicago, a ZO Clubhouse on the 23rd floor includes design-forward lounge areas, a built-in bar for events, and a conference center accommodating groups of 8 to 150. The ground floor features The Foyer, an all-day café created in partnership with Infuse Hospitality.

As of July 2026, ZO continues to expand across Tishman Speyer's global portfolio. The platform has become a central element of the firm's strategy to attract and retain tenants in a commercial office market where vacancy rates remain elevated and competition for occupancy is intense.
