in 2015, they weren't just looking to digitize receipts. They were looking to dismantle a fundamental friction point in corporate culture: the lack of trust between a company and its employees. In the early days, the expense process was a battlefield of missing receipts and gatekept company credit cards. Perra, the engineer, and Rindom, the CFO, saw that this wasn't a technical failure, but a human one. By issuing smart cards to every employee, they aimed to turn every worker into a trusted steward of company resources.
stands as a Danish unicorn, a testament to the power of solving a boring problem with a visionary approach. The platform handles everything from automated expense reports to invoice payments for over 25,000 customers across
co-working space to a multinational fintech powerhouse with 800 employees was anything but linear. It required a relentless focus on high-fidelity infrastructure and a deep, almost obsessive, commitment to understanding the psychological nuances of spending.
Why Your Co-Founder Should Be a Battle-Tested Ally
One of the most critical factors in the success of
and his co-founder. They didn't meet at a networking event; they worked together at a high-growth startup for years before venturing out on their own. This tenure allowed them to see each other under extreme duress—navigating tight deadlines, technical failures, and the messy logistics of setting up a
headquarters. This history of shared friction is what Perra considers the ultimate insurance policy for a startup.

He argues that founders must invest in "authentic leadership training" early. It isn't enough to like your partner; you have to understand their "hidden baggage." When a hard decision triggers a defensive reaction, you need to know if that response is based on the data at hand or a past professional trauma. By mapping out these psychological triggers, Perra and Rindom created a resilient leadership dynamic that could withstand the inevitable fires of scaling. For Perra, the human element isn't a soft skill—it is the bedrock of the entire enterprise.
Building the Hard Way to Own the Experience
In the mid-2010s, many fintechs chose the path of least resistance by white-labeling existing banking services.
took the opposite route. To provide the seamless, real-time experience they envisioned, they had to build their own infrastructure from the ground up and secure their own
issuing license. This was expensive, time-consuming, and technically daunting. It took a full year of backend development before they could even issue a test card.
to treat every card transaction as a row in a database, enabling features that incumbents couldn't touch. Perra recalls the early days of testing these blank, white cards at a local bakery. If a transaction failed, the developers would sit in the cafe, push a code fix, and try again. This iterative loop, while grueling, ensured that when they finally launched to a broader audience, the product wasn't just another card—it was a sophisticated financial instrument that integrated directly into accounting workflows.
developed a proprietary "launch manual." This wasn't just a technical checklist; it was a strategy for deep immersion. They sought out local accountants and power users to identify the specific "pain points" of each region. Perra warns against the temptation to over-promise and under-deliver during international expansion. In the world of finance, companies rely on your platform to meet legal obligations. A software bug in an expense report isn't just an inconvenience; it’s a potential regulatory nightmare for the customer. Maintaining a high bar for the "sub-par product" threshold was the only way to retain trust across borders.
is his perspective on the role of the technical founder. Despite his background as an engineer who has spent his life coding, he admits that "code is a very small part" of building a unicorn. The true challenge is people. As a company scales from a handful of developers to 800 employees, the founder's job shifts from solving technical problems to solving human ones.
Perra advocates for radical self-awareness: knowing your limitations and being willing to step back. The qualities that make someone a great early-stage engineer—focus, individual contribution, technical perfection—can sometimes be the very things that hinder them as a leader of a massive organization. By delegating to experts and focusing on the cultural health of the team, Perra ensured that
remained agile. He believes that if you surround yourself with smart people who genuinely care about the mission, there is no problem—technical, financial, or operational—that cannot be solved. This human-centric philosophy is what transformed
