AI-powered business banking platform Slash has secured $100 million in Series C funding, valuing the company at $1.4 billion. The capital will fuel product development for its AI-driven back office, designed for online businesses.
Founded in 2020, Slash offers a comprehensive suite integrating FDIC-insured checking, corporate cards with cashback, expense management, global payments, and stablecoin support. The platform operates as a software layer, with deposit accounts and card services provided by Column N.A. Corporate cards are issued by Visa, and treasury functions partner with Atomic Invest LLC to manage idle cash.
The platform also features an application programming interface (API) for custom workflow integration and provides specialized tools for various industries, including e-commerce, healthcare, and Web3 firms. Slash currently serves over 5,000 businesses.
The company's valuation surge follows a strategic pivot from serving sneaker resellers to providing business banking solutions enhanced by AI. Slash surpassed $1 billion in annualized card volume in 2024, reaching $3 billion in 2025.
The funding round was led by Ribbit Capital, Khosla Ventures, and Goodwater Capital LP, with participation from New Enterprise Associates Inc. and Y Combinator. Slash aims to position its platform as an autonomous finance function, automating financial back-office operations for business owners.
