For a long time, business banking felt like something founders had to tolerate rather than something that actually helped them grow. Opening accounts could be slow. Managing cards and payments often meant stitching together several tools. Day-to-day finance work felt heavier than it needed to be, especially for startups moving fast and making decisions in real time.
That gap is where Mercury found its opening.
Immad Akhund did not build Mercury as an outsider looking at the startup world from a distance. He built it after spending years inside it. Before Mercury, he had already gone through the pressure, friction, and unpredictability that come with building companies. He knew what it felt like to rely on systems that were not designed for the way founders actually work. That experience shaped the core idea behind Mercury and helped turn it from a startup banking product into one of the most talked-about fintech success stories in the market.
Today, Mercury is much more than a place for businesses to hold money. It has grown into a broader financial platform used by startups, ecommerce brands, venture firms, and other modern businesses that want better control over how money moves through their operations. The company’s rise says a lot about Immad Akhund’s product instincts, but it also says something bigger about how startup banking itself has changed.
Who Is Immad Akhund
Immad Akhund is the co-founder and CEO of Mercury, but his reputation in startups started well before Mercury launched. He had already built and sold a company, spent years around ambitious founders, and developed a deep understanding of how startups scale and where they tend to break.
Before Mercury, Akhund was the co-founder and CEO of Heyzap, a mobile developer tools company. That experience gave him firsthand exposure to the day-to-day reality of building a startup under pressure. He was not just learning how to launch products. He was learning how founders make decisions, how teams move when they are growing fast, and how often important systems lag behind the pace of the business.
That matters because Mercury did not come from abstract fintech theory. It came from lived experience. Akhund had already seen what founders needed from the tools around them, and he had also seen how frustrating it was when those tools were built around old assumptions.
He also became a well-known angel investor, backing a large number of early-stage startups. That gave him another lens into the founder journey. He was seeing patterns across companies, not just inside one. Over time, that helped sharpen the idea that business banking could be built in a more modern, more useful way.
The Frustration That Sparked Mercury
The most compelling startup stories often begin with a problem that feels obvious only after someone solves it well. In Mercury’s case, that problem was the mismatch between how startups operate and how traditional banking systems were designed.
Founders move fast. They need clean visibility into cash, flexible team permissions, reliable payment workflows, and products that do not add friction to already busy days. Traditional banking often felt too slow, too manual, or too disconnected from the rest of a company’s financial workflow.
Akhund started Mercury in 2017 because he had run into that same problem repeatedly while building his previous companies. The pain point was not small. Banking sits close to the core of how a business operates. When it feels clunky, everything around it slows down too.
That is what made the Mercury idea so strong from the beginning. It was not just about making a prettier interface for a bank account. It was about rethinking the banking experience from the founder’s perspective.
Building Mercury Around What Founders Actually Needed
Mercury’s early appeal came from clarity. It positioned itself around a simple but powerful belief: business banking should do more than store money. It should help ambitious companies operate better.
That meant focusing on usability, speed, and control from the start. Instead of forcing businesses into legacy workflows, Mercury aimed to create a product experience that felt more natural for internet-first companies. The platform was clean, straightforward, and intentionally built for modern operators rather than for slow-moving institutions.
This product focus became one of Akhund’s biggest strengths as a founder. He understood that startups were not looking for financial tools in isolation. They were looking for systems that saved time, reduced operational mess, and gave them more confidence in how they handled money.
Mercury launched its business account in 2019, giving founders a better way to manage core banking needs. But the long-term opportunity was always bigger than a single account product. Akhund and his team were building toward a wider platform that could handle more of the financial work businesses deal with every week.
Mercury’s Shift From Banking Product to Financial Platform
One reason Mercury’s success story stands out is that the company did not stop once it found traction with startup accounts. It kept expanding into the surrounding workflows that matter to growing companies.
That product expansion helped Mercury move from being a useful banking option to being a much deeper operating layer for businesses.
Over time, Mercury added corporate cards, bill pay, invoicing, accounting automation, and expense management. It later expanded into consumer-facing products with Mercury Personal and continued to broaden the ways customers could manage money from one system.
This shift matters because it reflects how founders actually want to work. Most businesses do not want a fragmented collection of disconnected finance tools if they can avoid it. They want products that fit together. They want accounts, cards, spend visibility, approvals, payments, and reporting to feel connected rather than patched together.
That made Mercury more valuable as customers grew. A startup might start with basic banking, but once it begins adding team members, vendors, contractors, and recurring financial processes, the need for integrated workflows becomes much more important. Mercury’s multi-product approach met that need directly.
From a leadership standpoint, this was one of Akhund’s most important moves. He did not let Mercury remain trapped in a narrow category. He pushed it toward becoming a broader financial software and infrastructure company, which made the business more durable and more relevant over time.
The Growth Milestones That Changed Mercury’s Position
Mercury’s story is not only compelling because of the problem it solved. It is compelling because the company translated that idea into measurable business momentum.
In March 2025, Mercury announced a $300 million Series C at a $3.5 billion valuation. That was a major signal that investors believed the company had grown well beyond its early-stage identity and was becoming a serious force in fintech.
Around that same period, Mercury said it served more than 200,000 companies, generated $500 million in annual revenue in 2024, and had achieved ten consecutive quarters of profitability. Those numbers gave the company a different kind of credibility. Plenty of startups raise money. Fewer combine strong growth, large-scale adoption, and sustained profitability at the same time.
Mercury’s momentum continued after that. By 2025, the company said it had reached more than 300,000 customers and $650 million in annualized revenue, while extending its profitability record and deepening product usage across its customer base.
Those milestones changed how Mercury was viewed. It was no longer just a promising startup banking brand. It had become a fintech company with scale, operating discipline, and a clear product roadmap.
For Akhund, that growth also reinforced a broader point about execution. Founder stories often celebrate vision, but lasting success usually comes from pairing vision with consistency. Mercury’s rise suggests he was able to do both.
Why Founders Trusted Mercury
Trust is one of the hardest things to build in any financial product. A sleek interface can get attention, but it does not keep businesses loyal on its own. Companies trust platforms that make important work feel easier, clearer, and more dependable.
Mercury earned that trust by staying close to the founder mindset.
It offered speed where people were used to delay. It offered cleaner design where users were used to clutter. It offered integrated financial workflows where businesses were used to juggling separate tools. The value was practical. Mercury made routine financial work feel more manageable.
That practical value is one reason the brand built strong loyalty among startups. According to recent public descriptions, 1 in 3 U.S. startups bank with Mercury. That is not just a sign of awareness. It is a sign that the company found real product-market fit inside one of the most demanding customer groups in business.
Startups have high expectations. They want speed, transparency, and products that do not waste time. If Mercury had only been good at marketing, it would not have earned that kind of adoption. Its growth suggests that the company was solving a real operational need in a way that felt better than existing options.
How Immad Akhund Turned a Founder Pain Point Into a Competitive Edge
What makes Immad Akhund’s success with Mercury especially interesting is that he did not just react to a personal frustration. He turned it into a broader business advantage.
A lot of founders encounter problems in their own work. Fewer are able to separate the emotional annoyance of a bad experience from the deeper market opportunity underneath it. Akhund recognized that the banking friction he had experienced was not unique to him. It was structural. It affected a wide range of founders and companies that had been forced to adapt to products that were not built with them in mind.
That recognition helped Mercury stay focused on the right audience and the right product choices.
It also helped Akhund avoid one of the common traps in fintech: building something that sounds innovative but does not become essential. Mercury became essential by solving workflows that businesses deal with constantly. It sat close to the operating core of the customer.
There is also a discipline to the way Mercury grew. The company did not only chase headlines. It built product depth, expanded use cases, and showed that it could operate profitably while scaling. That balance between ambition and discipline is part of what made Akhund’s leadership stand out.
What Mercury’s Rise Says About Startup Banking Today
Mercury’s success reflects a larger shift in what companies expect from financial products.
Business owners no longer see banking as something that should exist in a separate, outdated layer away from the rest of their operations. They increasingly expect the same level of usability, speed, and integration from finance tools that they expect from their best software products.
That shift created the conditions for Mercury to grow, but growth still depended on execution. Akhund and his team had to build a product that matched those expectations while also expanding with discipline.
The result is a company that now sits at the intersection of banking, software, and operational finance. Mercury started as a response to a founder problem, but it scaled because it understood where startup banking was heading before a lot of incumbents did.
That is what makes Immad Akhund’s story worth paying attention to. He did not just launch another fintech company. He helped define what a better banking experience for startups could look like, then built Mercury into a business strong enough to prove the market wanted it.
