Slash is building the future of business banking, one industry at a time. We believe businesses deserve financial infrastructure tailored to how they actually operate. That's why we're creating a new category of business banking.

We're backed by some of the best investors in the world including Menlo Ventures, NEA, Y Combinator, Stanford University, and the founders of Tinder and Plaid.
