There is a mythology surrounding entrepreneurship that suggests experience for second-time founders compounds. Build one company, learn the lessons, and your next venture should have a better chance of succeeding. But the evidence is more complicated.

Serial entrepreneurship is not unusual. Previous research suggests serial founders account for around 18% to 30% of entrepreneurial activity in Europe, while a large U.S. study found that roughly a quarter of new retail businesses were started by entrepreneurs who had founded a business before.

A 2024 stud y published in Small Business Economics found that repeat founders typically possess broader professional experience, more international exposure and higher educational attainment than first-time entrepreneurs. Yet the research stopped short of showing that serial founders consistently achieve superior outcomes. Other studies have found that while serial entrepreneurs can generate higher productivity, many underperform their first-time counterparts on measures such as capital efficiency.

Firsthand Knowledge Creates The Next Opportunity

So, if experience alone does not guarantee success, what exactly changes the second time around? For many founders, the most valuable lessons from a first company are not operational but contextual. Time spent close to customers reveals opportunities that would have been invisible at the outset.

That was the case for Per Österström, CEO and cofounder of Matters . Previously he was founder and CEO of Sambla Group, a venture driven largely by commercial ambition, with significant investment in sales and marketing.

“We weren’t old or experienced enough to understand or care about the really difficult customer problems and challenges in society. Instead, we built a strong business grounded in growth and profit,” he says. “Over time at Sambla Group, we gained hands-on experience and saw how many customers struggled with their financial situation - in a way we couldn’t have understood before we started the business.”

Learning How To Solve For Customers

Years of working closely with customers revealed deeper structural problems within both the market and the industry itself. “That gave us a clear picture of how to solve this for customers, and what foundational changes were required to improve the customer experience and transform the industry,” says Österström.

Experience also transformed the speed at which he handled another common startup challenge: people.

“Over time, you learn that when there is friction in a partnership or group, the feeling is often mutual,” he says. “If the friction is high and you avoid dealing with it and end up going separate ways, you not only make life worse for yourself; you make it worse for the other person too. It drains both your energies, and it doesn’t get easier over time. You also often underestimate how much the conflict affects the rest of the team. Today my patience is much shorter, but in a good way: after giving the partnership a real chance, I try to handle it straight away.”

Previous Experience Reduces Friction

A founder’s previous experience may not guarantee success, but it can dramatically reduce friction. Matters completed its most recent fundraising round in roughly two months from first conversations to signed commitments, allowing Österström to return his attention to building the business.

He says: “Investors recognized and appreciated the founding team’s and my own experience in B2C consumer finance, and that we could go both high-level and deep into the details when needed. Our collective domain knowledge garnered trust and confidence. Of course, Sambla’s success as part of my track record and the network I built up over that time made the fundraise go much faster than I initially expected.”

That pattern appears repeatedly among second-time founders. Their previous venture creates credibility before a product even reaches market.

Experience Changes How You Build

For Daniel Kjellén, cofounder and CEO of Freda , and previously cofounder of Tink, the most important lesson from his first company was knowing when not to scale. His philosophy today is simple: stay small until the business is truly ready to grow.

“With Freda, we are not raising until we know we are ready to scale,” he says. “Pivoting a company of over 100 people is complicated and much slower than pivoting a company of 20, and we learned that the hard way at Tink. This time, we’ve stayed small with the best talent you can find in the ecosystem and will remain so until we’re confident about where we’re headed.”

Establishing Trust In A Brand

The most valuable thing a successful exit provides, he argues, is trust. A founder who has successfully built a category leader before finds it easier to persuade customers to make a long-term bet.

He says: “It opens doors. Customers, design partners, potential hires, and investors are much more open to an initial meeting with us than they were a decade ago. Investors got in touch before we’d even launched, and some of the earliest Freda team members left their jobs to build with Fredrik, Adam and me, based on our vision and our work with Tink. Once the door opens, it’s on us to make it count, but getting there is much easier this time round.”

That credibility extends beyond fundraising and recruitment. “Customers instinctively trust that we understand their challenges with compliance, given that we’ve lived through perhaps one of the most complicated versions of it ourselves.”

The greatest advantage of building a second company may be psychological rather than operational. Experience creates perspective. Founders become better at distinguishing between noise and signal, and less likely to mistake activity for progress.

“What’s different this time around is the idea that headcount is a sign of success,” says Kjellén. “Tink was built at a time when it often was that indicator, and we tried to solve too many problems by hiring yet another team. What actually solves a problem is someone you trust being truly accountable for it. In an AI world, where great people can have ten times the output, that is the bar you need to set.”

Understanding The Reality Of Execution

Gabriella Sahlman’s first experience as a founder taught her something surprisingly simple: she enjoys the process of building. She had already built and backed companies before joining European private credit firm Fuels Capital as a cofounder, having previously cofounded Proventus Capital Partners and Xact Fonder and served on the boards of several Swedish companies, including Creandum.

In the early days of building Xact Fonder, there was so much to learn and so many things to do for the first time.

“I still remember writing the business plan with a book on how to write one open beside me,” she says. “For financial modelling, too, I went back to my textbooks. But as the business became established, I found myself drawn to the next challenge: building something else. That tells me I will keep coming back to building something new.”

Understanding How Outsiders See Your Business

Her experience as both investor and operator has also shaped her view of what outsiders often underestimate. Investors see strategy, financial projections and market opportunities. Founders live with the daily reality of turning those plans into execution.

“Even with an experienced team, building takes considerable time and attention,” she says. “You are constantly moving between long-term decisions and very practical problems. A good strategy matters enormously, but it only becomes valuable when people can execute it consistently. As an investor, it is easy to underestimate the effort required to get there.”

Experience Can Improve Judgement

Research suggests that founding experience alone does not guarantee a better outcome the next time around. What it does provide is something less measurable but perhaps more valuable: judgment.

Successful second-time founders are not just repeating what worked before. They are building with a clearer understanding of customers, a sharper sense of priorities and a more realistic view of what it takes to turn an idea into a company. That may not guarantee success, but it changes almost everything else.
