Cash App Founder’s Killer Learns Fate in Brutal San Francisco Murder

Nima Momeni has been sentenced to 16 years to life in prison for the murder of Cash App founder Bob Lee.

Momeni, 42, learned his fate nearly two years after the high-profile killing that shocked San Francisco’s tech community and drew national attention to street violence in the city. The sentence came after a jury convicted him of second-degree murder in the April 2023 slaying.

Lee, 43, was an influential figure in the technology world who had helped build Cash App into a widely used payment platform. His death prompted an outpouring of grief from Silicon Valley leaders and reignited debates about public safety in San Francisco.

The murder occurred in the early-morning hours of April 4, 2023, beneath the Bay Bridge in a secluded area of the city’s waterfront. Prosecutors said Momeni stabbed Lee through the heart during a confrontation, leaving the tech executive to bleed out on the pavement.

Investigators and prosecutors portrayed the killing as deliberate, though Momeni’s defense had argued the circumstances were murkier. The case dragged on for months as both sides prepared for trial in a homicide that became one of the most closely watched in San Francisco history.

The verdict and sentencing closed a chapter that began when Lee’s body was discovered in the predawn darkness, his phone and other belongings scattered nearby. Friends and colleagues had initially feared a random street attack, but investigators soon focused on Momeni, who knew Lee and had been with him hours before the killing.

Lee had left a gathering in the city with Momeni that night, surveillance footage showed, and the two men drove together to the isolated spot under the bridge. What transpired there became the central question of the trial, with prosecutors presenting evidence of a heated exchange and Momeni’s attorneys challenging the intent behind the fatal blow.

The case took on added significance because of Lee’s prominence in tech circles. He had previously worked at Square, now Block, where he helped develop Cash App, and had gone on to invest in and advise other startups. His death prompted tributes from executives including Block CEO Jack Dorsey and fueled a wave of media coverage about whether San Francisco’s crime problems were driving away the innovators who had defined the region’s economy.

Momeni did not testify at trial, and his attorneys sought to raise questions about whether the killing amounted to premeditated murder or something less calculated. The jury’s second-degree murder verdict suggested they found intent but not the advance planning required for first-degree murder.

The 16-years-to-life sentence means Momeni will serve at least 16 years in state prison before becoming eligible for parole consideration. Whether he ultimately wins release will depend on decisions by the parole board in the coming decades.

Lee’s family and the broader tech community have continued to mourn his loss in the nearly two years since the killing. The brutal nature of the death—stabbed through the heart in a deserted spot before dawn—added to the sense of shock that accompanied news of the murder.

The sentencing marks the end of criminal proceedings, though civil litigation related to the case may continue. For now, Momeni faces the beginning of a lengthy prison term while Lee’s legacy in the technology world endures through the products he helped create and the entrepreneurs he mentored.
