In the 1980s, he promoted roving parties that attracted the attendance of rich locals and celebrities. He is considered one of the most successful nightlight pioneers in Miami. Capponi also worked as a developer alongside Gregg Covin. Together, they used the parties to promote real estate projects in the area to celebrities and wealthy investors. Capponi's contributions to South Beach's development continued into the 1990s. With Covin, Armin Mattli, and Chad Oppenheim, Capponi in 2004 became one of the co-developers of
Ten Museum Park, a 50-story, 200-unit building in downtown. In 2010, he formed Capponi Construction Group. His firm was responsible for the renovation of Terra Veritatis, a 16-bedroom estate spanning 2.5 acres (1.0 ha) of Miami Beach completed in 2013.
The Wall Street Journal called the $40 million project "the most expensive renovation in the Miami area." Capponi and Gary Shear formed another company in 2013, Capponi Shear Construction, a general contracting firm. In 2014, Capponi joined the development team with
Moses Bensusan of Costa Hollywood, an urban beachfront development, by architect Hamed Rodriguez. The 500,000-square-foot resort consists of 307 fully furnished apartments. Now, Capponi has retired from the private sector and is fully committed to running his foundation, Global Empowerment Mission. ==Humanitarian work==
