    Success is a
    numbers game

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

    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.

    Standsome: Product before numbers doesn’t pay off #DHDL

    You can make many mistakes when pitching and talking to investors. But some are made much more often than others. In the final episode of the 12th season of "Die Höhle der Löwen", one of the most common could be observed.

    Taste like: The taste is convincing, but the logistics are not #DHDL

    Start-ups always have to deal with issues that do not exist for established companies. Especially in the food sector, there can be challenges that make it very difficult to "just find" a producer to produce the products that have already been very successful at trade fairs or food events in sufficiently large quantities for the retail trade. In the 7th episode of the 12th season of "Die Höhle der Löwen", some of these issues came up in the case of "Taste like". Exciting for the viewers, but especially for all founders who have similar plans.

    ichó: An emotional topic, but difficult numbers #DHDL

    A prominent advocate and investor, a highly emotional and important topic that moved several lions to tears at once, and promising initial results: ichó's training system, which is supposed to help dementia patients at least delay the disease, really left no one cold during its appearance on "Die Höhle der Löwen". In the end, however, there wasn't even an offer, let alone a deal. What didn't fit?

    CleverCakes: With numbers to success #DHDL

    No area of founders' knowledge and skills seems as neglected as numbers. And although investors - not only on "Die Höhle der Löwen" - never tire of stressing how important it is to know and communicate the most important figures of one's business, start-up events and trainings prefer to emphasise storytelling. In the 5th episode of the 12th season, however, founder Elina flashed the lions all along the line, but above all with her numbers. And thus shows how it's done right.
