Jonathan Goldstein

Co-Founder, CEO, Cain

Goldstein’s Cain investment firm has made a splash in luxury South Florida properties alongside Vlad Doronin’s OKO Group. It’s an unlikely coupling, given Goldstein and Doronin’s vastly different lifestyles and public personas. But it’s proved lucrative. 

Goldstein started as an attorney in his native London, where he still lives. Dubbed a “wunderkind,” he became a partner at international firm Olswang (now CMS) at 28, and then its CEO at 32. Goldstein keeps interviews focused on business and politics. Soviet-born Doronin, dubbed “the Russian James Bond,” has made headlines for dating fashion models. 

Cain, backed by Todd Boehly’s Eldridge Industries, and OKO completed the 57-story 830 Brickell in 2024, catching a leasing boom amid an influx of out-of-state companies looking for top-tier space. It is now fully leased, setting record South Florida rents. 

Their Miami condo towers include the finished Missoni Baia and Una Residences, expected for completion this year. Cain is also an investor in Doronin’s Aman Group, which has plans for an Aman Miami Beach hotel and condos in the historic Versailles building. The firm provided a $47.3 million construction loan to Bizzi + Bilgili and Sumaida + Khurana’s Miami Beach office building, and a $240 million loan for Related Group and Alta Developers’ Miami Casa Bella Residences by B&B Italia. It has also placed chips on the budding luxury condo market in Los Angeles, with its Aman-anchored One Beverly Hills project underway.
