Luxury Living in Miami: Cuban Billionaire Showcases His $175 Million Mansion

Tuesday, December 23, 2025 by Robert Castillo

Cuban entrepreneur John H. Ruiz, the brain behind Luminsea, has unveiled his stunning mansion located in Gables Estates, one of the most prestigious and high-priced neighborhoods in the United States, situated in Miami.

Valued at $175 million, this magnificent residence was showcased in a video by content creator Robert Sielmann, who praised it as "a fantastic home," not just for millionaires but for "billionaires."

Blending opulence with state-of-the-art technology, the property features a private nightclub, four swimming pools, a spa, a gym, a mini-golf course, and a private dock stretching over 400 feet. Moreover, it is fitted with a cutting-edge video and audio system, linked by more than 110 miles of fiber optic cable.

Ruiz, a Cuban native, amassed his wealth through diverse ventures in technology, maritime, and real estate sectors. He is also a lawyer and the owner of Cigarette Boats, a renowned name in high-performance watercraft.

His company, Luminsea, emerged from a family passion for sailing and a dedication to maritime safety.

Having learned to sail in his teenage years, Ruiz developed the Smart Channel Markers, an innovative technology aimed at enhancing safety on waterways, especially during nighttime or under low visibility conditions.

Residing in Miami with his children, who are also involved in his business ventures, Ruiz's mansion in Gables Estates not only epitomizes his financial success but also his vision of merging luxury, innovation, and a nautical lifestyle into a single domain.

Despite his wealth, Ruiz leads a relatively understated life and has expressed disdain for individuals who flaunt their riches.

"I don't care how much money someone has. I'm interested in their humanity, because there are those who think they are more important just because they have money. I don't like that, because I started from scratch," he stated in his interview with Sielmann.

The video has garnered millions of views and comments, highlighting the enormity and avant-garde design of the mansion. As the Spanish content creator remarked, “this house has it all,” and its owner is the central figure of an inspiring success story.
