Slash Raises $100M Series C to Scale Vertical Banking for Modern Businesses

Banks like to move slow, dress it up as stability, and call it a feature. Slash looked at that whole routine and decided speed, control, and precision might be a better business model, then went out and raised $100M to prove the point.

San Francisco has seen its share of fintech ambition, but Victor Cardenas Codriansky and Kevin Bai didn’t come here to blend in. They built into a gap most incumbents ignored, then widened it. Now they’re sitting on a Series C co-led by Ribbit Capital, Khosla Ventures, and Goodwater Capital, with NEA and Y Combinator leaning in again like conviction isn’t a question anymore.

The name does more work than people think. Slash. It implies reduction, speed, intent. And that’s exactly where this gets interesting. Traditional banking stacks are layered, slow, and allergic to specificity. Slash goes the other direction, tighter scope, deeper control, built for operators who don’t have time to wait on a system designed for everyone and optimized for no one.

Accounts, cards, payments, treasury… not new individually. But stitched together with real-time control and automation that actually moves with the business, not after it. That distinction is where companies either become tools or infrastructure.

More than $160M raised to date. A $1.4B valuation. That number isn’t just signaling scale, it’s signaling belief that verticalized finance isn’t a niche, it’s the direction. Start narrow, earn trust, expand with precision. That playbook keeps showing up, and it keeps working when the execution is tight.

The investor alignment sharpens the picture. Ribbit has a track record of backing financial platforms that don’t behave like banks. Khosla tends to bet where systems break and rebuild. Goodwater returning after leading the previous round says the internal metrics told a story worth running back. When those signals line up, it usually means something under the surface is compounding.

What’s unfolding here isn’t just another fintech raise. It’s a shift in how businesses expect to interact with money itself. Less waiting, fewer intermediaries, more direct control. Banking becomes embedded, programmable, and responsive, or it gets outpaced.

And if that trajectory holds, the companies building with this level of precision aren’t just participating in the system, they’re quietly redefining where the system starts and stops.
