Jonathan Goldstein

Few developers in Miami are as active as Jonathan Goldstein and his team at Cain International, the private real estate investment firm he co-founded that now holds $17.7 billion in assets. In fact, one could conceivably call Goldstein an original architect of Miami’s post-2010s commercial real estate renaissance. 

Goldstein described his firm as one of the “early miners in South Florida,” considering they started to invest in Miami in 2016, and have since decorated the city with luxury residential towers, renovated hotels and high-rise office developments across its various submarkets. 

There’s Una Residences, a 47-story luxury condo with 135 units in south Brickell; and Mission Baia, a 249-unit luxury condo in Edgewater; and then there’s the spectacular hotel renovation of South Beach’s Delano Hotel, an Art Deco marvel at 1685 Collins Avenue that opened in 1947 and hadn’t been retouched since 1994.

But no project has generated more attention, and greater praise, for Cain International than its 55-story office tower at 830 Brickell Avenue, a 1 million-square-foot, mixed-use behemoth that opened in 2024 (after years of delays) and quickly secured leases from top-flight corporate tenants. 

“The market-leading 830 Brickell has been our standout success — we’re 100 percent leased with unbelievably strong clients and tenants from Citadel and Santander to Microsoft and Kirkland & Ellis,” said Goldstein. “It’s highly unusual to have [an office] with zero percent vacancy, but that’s where we are. We have completely full rental levels that we never planned or imagined.”

A London native, Goldstein isn’t shy about stating why in recent years he chose to plant his flag in South Beach, as opposed to South Kensington. 

“I live in London, and it’s always gray. You move to Miami, and it’s always sunny — you’d want to be there as well,” he recalled, laughing. “Before the pandemic, I couldn’t understand why people criticized Miami, and didn’t regard it as a frontline American city. It has everything you need: infrastructure, education, amazing weather, sports.”
