Digital banking for businesses has never been more competitive. A decade ago, most companies had only one option – opening an account at a traditional bank, visiting branches, and filling out endless forms. Today, fintech platforms have completely redefined that process.
In 2025, three names often come up when founders or finance managers search for “modern business banking”: Meow, Mercury, and Brex.
Each claims to simplify how companies hold, move, and monitor their money. But which one actually fits your business needs?
This independent guide takes a clear, balanced look at what these three platforms offer, how they differ, and which type of company might benefit from each.

The Rise of Digital Business Banking
Why Companies Are Leaving Traditional Banks
Traditional banking still works, but for many businesses, it feels painfully slow.
Opening an account can take days, wires require branch visits, and reporting is often buried in PDFs. Startups, remote teams, and online-first companies need something faster – banking that feels like modern software.
That’s where fintech platforms entered the scene.
They offer online onboarding, real-time dashboards, and integrations with accounting tools like QuickBooks and Xero.
For many businesses, digital banking platforms have become not a luxury, but a necessity.
How Meow, Mercury, and Brex Fit Into That Landscape
Each platform serves a slightly different audience:
- Meow focuses on yield, automation, and global accessibility.
- Mercury aims at early-stage startups and venture-backed companies.
- Brex targets larger enterprises that need credit lines and expense control.
Let’s look at each one in detail.
