Adam Robinson, wife and two children among nine killed in Florida Learjet crash

Adam Robinson, the 44-year-old Austin tech entrepreneur who founded Retention.com and RB2B, was killed on Sunday, 1 November, when a Learjet 60 crashed in Palm Beach County, Florida. Eight others died with him, including his wife Helen Sharp and their two young children.

The family was flying from Austin, Texas, to the Bahamas and was travelling with their nanny and two friends. Early identification reporting named seven of the nine victims, with Adam Robinson’s name attached to the news that he, Helen Sharp and the children had died.

What happened in the Florida crash

Nine people died when the Learjet 60 went down in Palm Beach County. The identified victims included Adam Robinson, his wife Helen Sharp, and their two young children. The family had been travelling with their nanny and two friends, which brings the travelling party to seven people; the reports above do not name the remaining two victims or list the full nine-person manifest.

Who Adam Robinson was

Robinson was 44 and was the founder and CEO of Retention.com and RB2B, two bootstrapped companies. Reports describe him as a Wall Street veteran turned AI entrepreneur, as a multi-millionaire marketing-platform founder, and as an Austin tech boss. Helen Sharp is described as an artist and entrepreneur. The detail that fixes his profile is not a single valuation figure but the combination of two self-funded companies, a 44-year-old founder, and a family trip from Austin to the Bahamas.

Why his old X post went viral

After the crash, an old post by Adam Robinson on X resurfaced and went viral. Reports describe it as a plane-crash analogy and say it left social-media users in disbelief. The supplied coverage does not reproduce the post’s wording, so the exact line is not established here. The concrete point is the timing: it was not a new comment about the Florida crash, but an earlier message by Robinson about a plane crash that had already been posted before he died in one.

What is the NTSB looking at?

The NTSB investigation is focused on weather. The crew reported icing, turbulence and precipitation at 35,000 feet shortly before the aircraft began its rapid descent. Icing at that altitude matters because ice on wings and sensors can change an aircraft’s handling; those crew reports do not by themselves prove a cause. The reports above state no mechanical finding and no final cause, so the open question after the rapid descent is what the NTSB finds from the wreckage, weather data and crew communications.
