South Florida Dirt: A timeline of the Vacchi vs. Stern legal battle

Developer Michael Stern teamed up with Italian investor and TikToker Gianluca Vacchi in 2024. 

At the time, Stern said that Vacchi “understands new media and how to cut through the noise on social media in a way most real estate people don’t,” calling him an effective marketer and tastemaker. Online to his 22.1 million Instagram followers and 22.3 million TikTok followers, Vacchi has showcased his jetsetting lifestyle, workouts, cold plunges, and maybe most frequently, his dancing. 

Two years ago, Stern and Vacchi said they were 50-50 partners on a $4 billion pipeline of JDS Development’s projects (Stern’s firm). That included Mercedes-Benz Places Miami, the Dolce & Gabbana-branded 888 Brickell and the planned 1250 West Avenue project in Miami Beach. It later also encompassed a proposed condo buyout of the Casablanca Miami Beach. 

Since then, JDS and its partners have exited the 1250 West Avenue project. Both the Mercedes-Benz and Dolce & Gabbana condo projects are tied up in litigation, though sources previously told The Real Deal that JDS is in the process of securing new debt, and a new partner in developer Jeff Soffer for the stalled Mercedes-Benz Places, which would rescue the project. 

Meanwhile, Stern’s relationship with Vacchi has imploded. Vacchi sued Stern months ago, but that lawsuit was on hold, and further details of their dispute remained behind closed doors. 

Until recently.

Vacchi is accusing Stern of running a Ponzi scheme. In a new lawsuit, he alleges that Stern misrepresented the state of the projects, promising to use Vacchi’s investment in one development but instead diverting them to another. He also accuses Stern of violating a settlement agreement they reached this year. He wants Stern removed from the Mercedes-Benz project. 

Stern called Vacchi’s original lawsuit an abuse of the legal system that was filed “for the sole purpose of maliciously creating reputational destruction” and to extract a settlement from Stern, according to a separate lawsuit obtained by TRD. It’s unclear whether that suit was filed. Stern alleges that Vacchi failed to meet his capital obligations (in other words, didn’t invest on time, or at all). 

What we’re thinking about: What happens next with Stern? If the partnership with Soffer and the new financing closes, is all resolved? Send me a note at kk@therealdeal.com.
