The purchase of Groupalia and Offerum by Ofertix and La Nevera Roja by Just Eat that we have seen this week are a clear example that in the world of startups you have to know the right time to buy in order to win. Both the online discount market and the food delivery market boomed a few years ago, many startups were created, some of them who wanted to win, decided to grow through acquisitions, paying quite high prices, now these markets can no longer grow more and other startups buy these companies at a much lower price.
