So apparently you do need an MBA to find out that making your own coffee is not just a prerequisite when you decide to work for a startup, but also a skill, art and science.

Did you actually know that coffee is a cherry-like fruit? That people used to eat coffee? That the first coffee brewed probably tasted worse than dishwasher water? Some still do apparently...Well, three months ago when we had the glorious idea to get into the coffee trade, we did not even know the difference between an arabica bean and a hazelnut...

The easier part for sure was to make assumptions out of thin air, validate them in an Excel sheet, prove the business case in Word and prepare an outstanding summary presentation in power point. Not really - now the real work is to actually get the milk foam just about the right temperature and consistency so that the hearts you attempt to draw on your latte do not look like rotten apples.

More importantly, now we know better: not just do our hearts look legit,.but we also know our Colombian from the Ethiopian and get the milk to espresso ratio right, we know a flat white from a cappuccino and understand why you should never never never keep your beans ground and exposed to air.

The longest practical class and exhausting learning curve along the coffee belt - but totally worth it when your new office smells of fresh ground coffee every day.
