@andre.cronje is like a Doctor or a Teacher, we cant have money to pay him, and i dont think he is most interessed about earning as many money. People who like so many money go to trade or do others stuffs, but when someone create something liks this and others also benefit of. i really dont think money is him primary source of motivation.
Althea is a best example, like us in Haiti we dont have good connection, i contacted them to see how they can come in Haiti but the cost of internet provider is so high and they cannot. But they are a very good startup to invest in.
