Sequoia Capital is making a bet on the future of Wall Street, leading an investment in Rogo Technologies Inc., a startup developing artificial intelligence tools to make bankers more efficient, at a valuation of $750 million, according to people familiar with the matter.

The New York-based company builds software that helps investment bankers with certain tasks and eventually aims to create the AI equivalent of a banking analyst. The new deal more than doubles Rogo’s valuation from earlier this year, when Thrive Capital led a $50 million Series B investment in the company.
