His company is http://www.ave4.com/ I meet him a few times, interviewed to work there (didn't get the job.) I mostly talked to a lawyer who was very nice, but reminded me of Kobayashi from the Usual Suspects. The offices are a bit extravagant with some amazing original artwork on the walls, https://www.jendoco.com/portfolio/fourth-avenue-analytics/

Pre covid he hosted meetups with Pittsburgh's R Users Group, https://www.meetup.com/Pittsburgh-useR-Group/events/26070166...

He is also mentioned in http://www.fortunesformula.com/ which I really enjoyed.
