Bob Lee, a technology executive who created Cash App and was MobileCoin’s chief product officer, was fatally stabbed early on Tuesday, according to MobileCoin and the San Francisco police.

In a press release, the San Francisco Police Department said that officers responded to a stabbing call on Main Street at 2:35 a.m. Tuesday and found a 43-year-old man with what looked like stab wounds. A hospital is where the person died.

The victim was not named by police, but MobileCoin confirmed Lee’s death on Wednesday in response to an email from The Associated Press.

“Our dear friend and colleague Bob Lee died yesterday at the age of 43. He is survived by a loving family and a group of close friends and coworkers,” MobileCoin CEO Josh Goldbard said in a statement.

Goldbard wrote that Lee was “made for the new world.”

“Bob made big contributions to Android at Google, was the first CTO of Square, created CashApp during that time, and worked with us here at Mobilecoin,” he said. “His work will be felt long after he’s gone.”

Goldbard said that Lee joined MobileCoin as an early investor and advisor. He later became the company’s chief product officer and helped launch the Moby app. In 2013, Lee oversaw the launch of Square’s money transfer app, which is now known as Cash App, while at Square, a digital payments company.

The police statement didn’t say anything about what happened before or after the stabbing.
