    Success is a
    numbers game

    My articles explain more about the importance of numbers when negotiating with investors.

    eSelly: When not to think directly about earning money #DHDL

    In "Die Höhle der Löwen", the questions about turnover and earnings of the young companies are among the most important. Often not included in the finished version, but just as important are the numerical questions aimed at determining when the start-up in question might be able to earn money. But sometimes everything is different. The example of eSelly was a good illustration of the requirements that have to be met by investors for such a special case.

    Brilamo: Hero of the day with unagitated competence instead of visionary poseurism #DHDL

    You know them well - the overconfident, visionary, sometimes slightly hyperactive founders who talk about great plans, have optimised their storytelling down to the last detail - but then also demand very self-confident assessments from investors. But on this Monday, Linda from Brilamo showed us that you can also make investors rave in a completely different way - and was overwhelmed with superlatives. Is this the new type of founder that can become a role model?

    Tinus: Milestones also exist for investors #DHDL

    Many founders are very familiar with so-called milestones in an investment. But almost all of them associate them with the fact that their start-up has to achieve certain goals in order to continue receiving money from investors. But it also works the other way around. In the latest episode of "Die Höhle der Löwen", you can see very well how something like this can work, using the example of the start-up Tinus from Munich.

    NewMa: A previously ignored market #DHDL

    Many new markets arose because someone noticed a problem and wanted to solve it. Such a market grew particularly quickly if the problem was not insignificant - i.e. caused a certain amount of suffering - and was relevant to as large a number of people as possible. The pain and problems that most women experience after childbirth actually fit right in, yet they have been offered solutions that don't really deserve the name. How could it be that such a large and willing-to-pay market has simply been ignored until now?

    Papydo: Why the elbow-less form of negotiation makes more sense for start-ups (and investors)#DHDL

    On both the startup and investor side, there is still a strong attitude that negotiations have to be tough. Many founders in particular believe that going in with a slightly higher valuation and then wrestling for every percentage point is simply part of the game. Investors, on the other hand, sometimes seem to see it as one of their core tasks to negotiate founders down a bit more in any case. But is this time-honoured, very patriarchal way of negotiating really the right one in this setup? In the Christmas episode of "Die Höhle der Löwen", the founders of Papydo show how things can be done differently. Why this could and should set a precedent.
