4. SalesForce’s Marc Benioff
Benioff’s love of Hawaii was the motivation for his purchase of a 5-acre estate on the edge of the Mauna Kea Resort. The 30-year-veteran of SalesForce Inc. embraces his life here, wearing Hawaiian shirts to work, and playing with his dog “Koa” – named after a species of tree native to Hawaii. His $12.5 million property is located immediately next to the Lurline Roth Estate.
