Slash, a vertical banking platform built by two college dropouts, has raised $100 million in a Series C round, backed by Khosla Ventures and Ribbit Capital. The company's valuation has nearly quadrupled since its May 2025 Series B. The move follows a significant turnaround since Slash's core market evaporated due to Kanye West's anti-Semitic statements. Despite this, the company pivoted to vertical banking for online businesses, focusing on specific sectors rather than a horizontal market. The new round values the company at nearly four times the original $370 million valuation. The platform now serves verticals including web3, e-commerce, agencies, affiliate marketers, healthcare suppliers, online travel agencies, and wholesalers.
