 My big challenge was my first fund that it was from the traditional bank but in the traditional bank funds my challenge was to speak about products that doesn't exist in the market because my raw material is cork. So it was not easy to convince my investors that I want to work cork and they asked me, but wow, you see that answer. So I think it was my biggest challenge is when you have a different product, when you have a different business, then you want to sell not only for the customer but special to your investors.
