New York CNN —This week, the go-to bank for US tech startups came rapidly unglued, leaving its high-powered customers and investors in limbo. Silicon Valley Bank, facing a sudden bank run and capital crisis, collapsed Friday morning and was taken over by federal regulators. Founded in 1983, SVB specialized in banking for tech startups. At the same time, venture capital began drying up, forcing startups to draw down funds held by SVB. By Friday morning, trading in SVB shares was halted and it had abandoned efforts to quickly raise capital or find a buyer.
