What is a Startup Idea? Why do you need one? When is it a good idea? This first (primer) section dives right in with some of the core concepts we'll use throughout the course, and gives you a detailed overview of what's in the rest of the course. 

Before you start on the - potentially life changing - journey of building a startup, you need to know why you want to do that. That is important, among other things, because it will help you decide the best direction to take later on.

Let’s face it. The point of view you have defined in the previous model is just a nicely packaged stack of assumptions, since they have not been tested against the real world.

You need to start understanding what the problem you want to solve and your point of view mean to the people that have the problem in the first place: your customers. What do they think?

Learn to fall in love with the problem.

There is no single right solution. It's vital to come up with a lot of options to choose from, and you can use creative tricks to make coming up with them a lot easier!

he last module has probably left you with somewhat of a problem. 

The chances are, you have generated hundreds of possible options. And once you generate hundreds of different ideas for your business, how do you choose which ones to work on first? How can you make an informed choice? What are the tools you can use to help you? 

All those ideas may look super promising, but they are built on a shaky foundation of assumptions. If one or more of these assumptions turn out to be wrong, the whole house of cards can come tumbling down. Validation is about testing those foundations early, before building too much on top of them.

Now that you have gone through a round of validation for your ideas, it is time to check if you have reached your goal, and to decide your next course of action.
