For startups, the bank account isn’t just a place to hold money—it’s the beating heart of every financial decision. It’s where investor capital lands, payrolls get processed, bills get paid, and data gets recorded. From day one, it sets the tone for how a company handles growth, discipline, and ambition.
But while consumer banking has gone digital, business banking—especially for startups—has struggled to catch up. Many founders still face sluggish processes, outdated interfaces, and friction-filled workflows at traditional banks. That’s a problem when your business model depends on moving fast and scaling efficiently.
Startups need more than just a bank account. They need a platform that understands the complexity of modern financial operations, adapts to changing needs, and doesn’t make them choose between functionality and design.
Ambitious companies use Mercury’s banking and software to power all financial workflows. And what are startups if not ambitious companies in their purest form?
Below, we take a closer look at Mercury—and why it’s quickly becoming the best business banking platform for startups in 2025.
Mercury: Built for Ambition
Startups don’t just need a bank account—they need a launchpad. Mercury is the fintech ambitious companies trust for banking, credit cards, and all their financial workflows. And it all begins with a single, powerful core: the business bank account.
Mercury’s banking experience is different by design. Because it’s a fintech company not a bank, it isn’t held back by legacy systems. Instead, Mercury partners with banks like Choice Financial Group, Column, N.A., and Evolve Bank & Trust, Members FDIC, to provide the regulated backbone—while it focuses on what it does best: crafting an intuitive, modern platform that helps startups operate at their best.
That means faster, smoother ways to move money. Capital products with startup-friendly terms. Interfaces that actually make sense. But banking is only the beginning.
Startups also need to issue payments, manage spend, invoice clients, and reconcile the books—often with limited time and lean teams. So Mercury built more than a bank. It built financial software directly into its platform, keeping all money flows accurate, up to date, and in sync. From AI-powered invoice creation to recurring bill pay, Mercury’s tools are engineered for speed and clarity—qualities that define the best business banking platform for startups.
And startups are responding. In March 2025, Mercury announced a $300 million Series C round led by Sequoia Capital, with participation from Spark Capital, Marathon, Coatue, CRV, and Andreessen Horowitz. The round valued the company at $3.5 billion.
Founded in 2017, Mercury now serves more than 200,000 companies across industries like tech, e-commerce, and venture capital. Its revenue in 2024 reached $500 million, backed by ten straight quarters of profitability. Customer growth continues to accelerate, with a 40% year-over-year increase and $156 billion in annual transaction volume—up 64% from the year before.
With more than 700 employees and a Net Promoter Score of 75 (more than double the industry average), Mercury is redefining what startups should expect from business banking.
What Powers Mercury: Inside the Banking Stack
Mercury doesn’t just offer a bank account—it gives startups a full-stack banking experience designed to simplify financial operations and scale with ambition.
At the heart of Mercury is what it calls the banking stack—a curated collection of tools, accounts, and features that work together to streamline how businesses manage money. Instead of piecing together disconnected services, founders get a cohesive, flexible platform tailored to the needs of growing companies.
Here’s what’s included in Mercury’s banking stack:
- Business checking and savings accounts¹
- Business debit cards*
- ACH and check payments
- Domestic and international wire transfers
- Digital tools and software integrations
Together, these components turn Mercury into more than just a place to hold funds. It becomes a command center for finance teams—whether that’s a founder managing the books solo or a growing startup scaling operations. Mercury’s flexibility gives users greater control over their banking experience while automating the busywork that tends to bog teams down.
From seamless payments to multi-user access and permissions, Mercury helps startups move faster without sacrificing clarity or control—qualities that continue to position it as the best business banking platform for startups.
¹ There are no fees to open an account or transact with Mercury Treasury. You’ll be charged a small percentage of your total monthly Mercury Treasury positions at a rate determined by the total deposits held across all your Mercury accounts, ranging from 0.15% to 0.60%. All yield figures are net of fees.
*The Mercury Debit Cards are issued by Choice Financial Group and Evolve Bank & Trust, Members FDIC, pursuant to licenses from Mastercard.
A Closer Look at Mercury’s Business Checking Account
Mercury’s business checking account is where ambitious startups find both structure and flexibility. With accounts offered through FDIC-insured partner banks—Choice Financial Group, Column N.A., and Evolve Bank & Trust—users can secure their funds while accessing tools built for speed and scale.
Through sweep networks, Mercury offers up to $5 million in FDIC insurance, ensuring that even companies managing large balances can bank with confidence.* For startups looking to put idle cash to work, Mercury Treasury provides access to SIPC-insured money market portfolios that combine protection with meaningful yield.
But beyond security, what sets Mercury apart is how it transforms the day-to-day of managing finances.
Founders and finance teams can make scheduled or recurring payments via ACH, wire, or check without the usual friction. Invite as many team members as needed, and set clear access levels—admin, bookkeeper, or fully customizable permissions. You can even define approval thresholds for large transactions or limit who’s authorized to make payments.
For businesses that want to move faster, Mercury offers automation across the stack. Set up auto-transfer rules between accounts and approve payments directly in Slack. Mercury doesn’t just sit alongside your accounting tools—it plugs right in. With advanced financial workflows, startups can automatically sync transactions and records across platforms like QuickBooks, Xero, and NetSuite. It’s all about saving time, cutting manual work, and keeping your books effortlessly up to date. Even payroll becomes easier through wire drawdown support.
In short, Mercury’s business checking isn’t just a holding tank—it’s a dynamic tool that helps startups scale operations while staying in control.

Certain services, like sending non-USD international wires or exchanging currencies, come with clear, upfront fees. For example, there’s a 1% currency exchange fee for non-USD wires, and 1.5% cashback on credit card spend. Mercury supports wires in 40+ currencies and allows for both check deposits and check sending.
