Tom Killi has spent over three decades building systems that learn from outcomes. In 1996 he founded x.hlp Technologies, enterprise software adopted by Fortune 500 companies including JPMorgan and Shell before its 2004 acquisition — the technology eventually became part of SAP. His patent from that era has since been cited by more than 50 later patents from companies including Microsoft, Apple, and IBM. He founded Wyetree in 2014, building energy trading infrastructure, and founded CleanAim in 2020. He is based in New York.
