Borrowing to bootstrap: set the stopping rule first

Seth Godin’s short book The Dip, published in 2007, picks a fight with the old coaching maxim that quitters never win. His answer: “Winners quit all the time. They just quit the right stuff at the right time.” It is usually read as career advice. It works just as well for the money a founder borrows before a business can pay its own way.

In Poland those months are paid for, overwhelmingly, by the founders themselves. Statistics Poland asked the businesses registered in 2023 that were still trading in 2025 how their start had been financed, and 88.3% named their own funds. Domestic loans and credit, together with money from abroad, came to 3.4%. Own funds is a generous category. For some founders it means savings. For others it means a personal loan or a card limit taken out in their own name and paid into the business account.

Months the state makes cheap

Poland makes the first stretch unusually cheap to sustain. Someone registering a sole trader’s business for the first time, or for the first time in five years, can take the relief called ulga na start: six full calendar months without social insurance contributions, paying only the health contribution, which in 2026 is at least 432.54 zł a month for anyone taxed on the scale or the flat rate (conditions on biznes.gov.pl). Then come 24 months of preferential contributions, calculated on 30% of the minimum wage and costing 456.18 zł a month in 2026. After that, a firm with revenue under 120,000 zł can move to mały ZUS plus, with contributions tied to income for up to 36 months in any 60.

ZUS worked out in February 2026 that a founder who started in January 2026 and used every relief until July 2031 would pay about 73.5% less in social contributions than on the standard terms (ZUS analysis, February 2026). The same paper warns that lower contributions now mean lower benefits later, and the months of ulga na start do not count toward pension entitlement at all.

That is sensible policy with a side effect. When staying registered costs a few hundred złoty a month, almost nothing outside the founder forces a verdict. A venture that is not working can be kept alive for a long time on small sums, and the smaller each sum, the easier it is to add one more. Plenty still end early. Of the Polish firms that started in 2024, 68.4% were still active a year later, so roughly one in three was not.

Write the rule before the money arrives

Borrowing to fund an experiment can be a reasonable decision. A founder who has costed the idea, found early interest and needs a few months to learn whether customers will pay is using credit for something credit can do. The danger is rarely the first loan. It is the second and the third, each one taken when the experiment has not yet given its answer and the money already spent argues for a little more time. Sunk cost does its work at the moment judgement is weakest: late in the month, with a payment due, after enough effort that stopping would make all of it look wasted.

Where to stop is not something a lender decides. A founder weighing the bank’s personal loan against a card limit, or against a short loan taken online from Avinto, will see each offer’s price and repayment date before signing, and none of the three will ask what happens to the business if the date arrives and the customers have not. That question stays with the borrower, and the only good time to answer it is before the first loan, while nothing has yet been spent.

So the decision is made in advance, on paper. A stopping rule names the most that will be borrowed across the whole experiment, counted in total and never loan by loan. It names the day the experiment will be judged, whatever the mood on that day. And it names the figure that has to have moved by then: paying customers, monthly revenue, a signed contract, anything that can be counted rather than argued about. The Polish relief calendar supplies two obvious dates for free, the end of month six, when social contributions begin, and the end of month thirty, when the preferential base runs out. A copy of the rule belongs with someone who will ask about it, because a limit kept only in the founder’s head gets renegotiated each time it comes due.

Two more lines are worth adding. No new loan is ever taken to repay an earlier one, since at that point the experiment has stopped testing anything. And the total is kept small enough to be repaid from ordinary income if the experiment is stopped on schedule. If repayment depends on the business succeeding, stopping would mean defaulting, and nobody keeps a stopping rule on those terms.

Borrowing because the household has already run short, to cover rent or bills that income no longer reaches, is a different matter altogether, and nothing here speaks to it. A stopping rule is for money put at risk by choice.

What stopping looks like

Reaching the date with the number unmoved does not have to mean closing the business. A sole trader with no employees can suspend it in the CEIDG register, for a fixed period or indefinitely, and owes no social contributions while it is suspended. That leaves room to take paid work, repay what was borrowed and look at the idea again later with a clear head. One detail belongs in the plan from the start. Both the six free months and the 24 preferential ones are available only to someone starting for the first time or after a gap of at least sixty months since the last suspension or closure. A second idea tried soon after the first pays standard contributions from its first month, and a stopping rule that leaves some savings untouched is what keeps that second attempt affordable.

Written down, the whole rule fits on a card: twelve thousand złoty in total, judged on the last day of March, stopped unless twenty customers are paying every month by then. The figures will differ for every business. What matters is that they were chosen at the outset, by someone who had not yet spent anything, and not in March by someone who had.
