Chainalysis co-founder Michael Gronager sold his waterfront house in Miami Beach for $16.5 million, three months after stepping down from his company and announcing his move to New York.
Records show Gronager’s Flaminglet LLC sold the house at 2901 Flamingo Drive to Joya Land Trust, managed by Florida Flamingo LLC, a Delaware entity.
Jeri Jenkins and Brian Alexander with Coldwell Banker Realty had the listing, and Jorn Lahmann with Lahmann Global Real Estate brought the buyer.
Gronager co-founded the New York-based blockchain forensics firm Chainalysis in 2014. He stepped down as its CEO in December, posting on LinkedIn, “I plan to make New York my stumping ground again very soon.”
Gronager could be referring to the duplex he bought last month at 67 Franklin Street in Manhattan’s Tribeca neighborhood. He dropped $11 million on the penthouse, which was featured in the Netflix show “Owning Manhattan.”
He bought the Flamingo Drive house for $14.8 million in 2023, records show. The 6,400-square-foot home was built in 1935 on a half-acre, and expanded and renovated in 2016, according to property records. It has six bedrooms, five bathrooms, one half-bathroom, a pool, a gym, a red light sauna and 300 feet of waterfront, according to records and the listing.
Gronager listed it for $18 million in January, Zillow shows.
It marks the latest pricey Miami Beach deal in South Florida real estate’s busy season. Earlier this month, spec developer Philippe Harari’s AquaBlue Group bought a waterfront lot on North Bay Road for $17.5 million. Last month, a waterfront teardown sold for $25.5 million. The splashiest deal of the season has yet to close though: Developer Todd Glaser went into contract in February for a waterfront North Bay Road estate for $105 million.
