Adam Robinson, a 44-year-old technology entrepreneur from Austin, Texas, was among the nine people killed in the Learjet 60 crash in Palm Beach County, Florida, on Sunday, November 1. Robinson was traveling with his wife, Helen Sharp, their two children, their nanny, and two close friends when the $2 million private jet crashed while en route from Austin to the Bahamas. The aircraft’s two pilots were also killed.
Robinson was the founder and chief executive of Retention.com and RB2B, two software-as-a-service (SaaS) companies that focus on identifying anonymous visitors to websites. He built both businesses into high-revenue ventures with relatively small teams and without traditional venture capital funding.
According to an estimate shared by entrepreneur and investor Sam Parr in May 2025, Robinson’s personal net worth was around $6 million, excluding the value of his businesses. However, his latest net worth is not known.
