43-year-old Bob Lee was stabbed to death on the street at 2:35 a.m. in the city of San Francisco.

He was rushed to the hospital but didn’t survive. Police responded to the stabbing near the 300 block of Main Street in SoMa.

No arrest has been made in the case as an investigation continues.

Known as “Crazy Bob,” Lee was a major investor in tech startups. He also created the wildly popular app called “Cash App,” which allows users to easily pay each other and securely transfer funds.

According to his LinkedIn profile, Lee had invested in SpaceX, Clubhouse, Tile, Figma, Faire, Orchid, Addressable, Nana, Ticket Fairy, Gowalla, Asha, and others.

He worked at Google for the first few years of Android and later joined Square, the payment company which became Block.

San Francisco Police Department hasn’t shared any other details.

“It’s real. Getting calls. Heartbreaking. Bob was instrumental to Square and Cash App. STL guy,” Jack Dorsey, the CEO of Block, said.

“So sad to hear of @crazybob’s untimely passing. I first met him in summer 2006 — he didn’t care that I was only 14 and we talked tech / geeked out about programming. We remained connected over the years and he was an early supporter of Figma. It’s so hard to believe he is gone,” Figma CEO Dylan Field said.
