The body of Fahim Saleh was found dismembered in a flat on Monday afternoon, US media reports say.
Police have not publicly commented on the case or any identity but Gokada, one of the firms Saleh co-founded, tweeted to confirm his death.
“We are deeply saddened to inform you about the sudden and tragic loss of our founder and CEO, Fahim Saleh,” the firm said on Wednesday.
According to US media reports, CCTV footage from the building in which Saleh lived showed him entering a lift with a man wearing a mask on Monday.
His body was reportedly discovered decapitated and dismembered, with an electric saw placed nearby.
An unnamed source in law enforcement told the New York Post the crime scene looked like a “professional” killing.
