Former CTO of Square and Cash App developer Bob Lee was fatally stabbed

MobileCoin’s Bob Lee, the company’s chief product officer, was fatally stabbed in San Francisco.

The San Francisco Police Department responded to a complaint of a stabbing along the 300 block of Main Street in SoMa on Tuesday morning at 2:35 a.m. Despite being brought to a hospital, he passed away from his wounds.

Soon later, NBC Bay Area reported that 43-year-old Bob Lee was the stabbed victim. In a statement provided to Bloomberg and ABC7 News, MobileCoin confirmed the details.

Bob Lee worked with Google during the early years of Android, concentrating on core library development, before joining MobileCoin. To create Square’s Android app, he later joined Square, the payments firm that ultimately changed its name to Block. He founded Cash App and rose to the position of the company’s first CTO.

Bob Lee, sometimes referred to as “Crazy Bob,” invested in computer start-ups. He made investments in companies like SpaceX, Clubhouse, Tile, Figma, Faire, Orchid, Addressable, Nana, Ticket Fairy, Gowalla, Asha, SiPhox, Netswitch, Found, and others, according to his LinkedIn page.

The tech community had an outpouring of grief after hearing the news. “It’s true. receiving calls. Heartbreaking. Bob was crucial to the success of Square and Cash App. STL person,” commented Block CEO Jack Dorsey on nostr.

“Sorry to hear about @crazybob’s premature passing. He didn’t care that I was only 14 when I first met him in the summer of 2006, and we geeked out over technology and programming. He was an early supporter of Figma, and we stayed in touch over the years. It’s really difficult to accept that he is no longer with us, Figma CEO Dylan Field tweeted.

Such a disaster. I can still picture Bob’s code, which produces specific numbers. Although Bob’s code is written in Java, it employs ingenious backtracking strategies to obtain the best performance out of numerous alternatives in other languages, according to a post by hintymad on Hacker News.

The San Francisco Police Department has not released any more information about the incident or made any arrests in connection with it.
