A private jet crash in Palm Beach County, Florida, on November 1 claimed the lives of nine people, including Austin-based technology entrepreneur Adam Robinson, his wife, their two children, and other passengers aboard the aircraft.
Robinson, 44, was the founder and chief executive of Retention.com and RB2B, two software-as-a-service (SaaS) companies known for helping businesses identify anonymous visitors to their websites. He was traveling with his family and two close friends on a Learjet 60 that was flying from Austin, Texas, to the Bahamas when it crashed. Both pilots were also killed.
Beyond his work in the technology industry, Robinson had built a reputation as an entrepreneur who grew businesses with relatively small teams and without relying on traditional venture capital funding.
His personal net worth was estimated at approximately $6 million in May 2025, according to an estimate shared by entrepreneur and investor Sam Parr. That figure did not include the value of his businesses. His latest net worth remains unknown.
Here are five things to know about Adam Robinson, including his estimated wealth, Wall Street career, business ventures, and family.
1. Adam Robinson’s Estimated Net Worth Was $6 Million
Adam Robinson’s personal net worth was estimated at around $6 million in May 2025, based on figures shared by entrepreneur and investor Sam Parr.
The estimate excluded the value of Robinson’s companies, Retention.com and RB2B. Both businesses operated in the software-as-a-service industry, focusing on tools that help companies identify and understand website visitors.
However, the $6 million figure should be treated as an estimate rather than a confirmed financial disclosure. There is no updated public figure available in the information provided, and his total business holdings and assets have not been independently established.
2. He Spent 10 Years Working on Wall Street
Before entering the technology industry, Robinson spent approximately a decade working on Wall Street.
His LinkedIn profile listed previous positions at Lehman Brothers and Barclays Capital, two major names in the financial services industry.
After leaving traditional finance, he shifted his attention toward technology and entrepreneurship. He later launched an artificial intelligence startup called GetEmail, marking an important step in his move toward software and business technology.
His experience in finance helped shape the business background he brought to his later ventures.
3. He Founded Retention.com and RB2B
Robinson became widely associated with Retention.com and RB2B, the two software companies he founded and led as CEO.
He established Retention.com in January 2020 and launched RB2B in September 2023.
Both companies focused on identifying anonymous visitors to business websites and helping companies turn that information into potential sales and marketing opportunities.
RB2B offered a service that could provide businesses with LinkedIn profiles of identified website visitors in real time, giving sales and marketing teams additional information about potential customers.
One notable aspect of Robinson’s business approach was his decision to bootstrap both ventures rather than depend on traditional venture capital funding.
He reportedly grew the companies into high-revenue businesses while maintaining relatively small teams. His approach attracted attention among entrepreneurs interested in building software companies without following the traditional startup funding model.
4. He Also Launched an AI-Focused Venture Called MoltSets
Robinson’s business interests extended beyond Retention.com and RB2B.
He was also listed as the founder and CEO of MoltSets, an AI-focused company he joined in June 2026.
Based in the Austin metropolitan area, MoltSets offers contact data APIs designed for AI agents.
The venture reflected Robinson’s continued involvement in the technology sector, particularly in products connected to artificial intelligence and business data.
5. His Wife and Children Were Also Among the Victims
The November 1 plane crash also claimed the lives of Robinson’s wife, Helen Sharp, their two children, Emma and Charlie, and other passengers traveling with the family.
Sharp operated a communications firm called Influential PR and owned Helen Sharp Ceramics, a pottery studio based in Aspen. The family lived in Austin, Texas.
The couple’s nanny was also among those killed in the crash. A report published by Times Now provided additional information about the victims.
Two close family friends and the aircraft’s pilots also died. The pilots were identified as Jeff Gregory, 55, and Nathalia Gadelha Filgueiras, 20.
The identities of the two family friends had not been publicly disclosed in the reports provided.
The Palm Beach Post previously quoted the father of one of the victims describing the loss as devastating. He said, “It’s quite a blow. We had a daughter, her husband and two grandchildren on the plane.”
Federal authorities had not released details establishing the cause of the crash in the information available for this report.
