Cash App founder Bob Lee reportedly killed in San Francisco stabbing

A man who was fatally stabbed early Tuesday near downtown San Francisco was tech executive Bob Lee, the founder of Cash App and former chief technology officer of Square, sources told NBC Bay Area.

The San Francisco Police Department said officers responded to a report of a stabbing at around 2:35 a.m. Tuesday. They found a 43-year-old man with apparent stab wounds.

The man was taken to a hospital with life-threatening injuries and later died, police said.

Authorities did not name the man, but sources identified Lee as the victim to NBC Bay Area. He had been serving as the chief product officer of the cryptocurrency company MobileCoin.

In a statement Wednesday, the chief executive of MobileCoin said that Lee “passed away yesterday” and praised his business acumen. He did not specify Lee’s cause of death.

“Bob was a dynamo, a force of nature. Bob was the genuine article,” Josh Goldbard said. “He was made for the world that is being born right now, he was a child of dreams, and whatever he imagined, no matter how crazy, he made real.”

No arrests appeared to have been made as of early Wednesday.
