Businesses are borne out of a problem. This may be a problem experienced personally, a frustration with existing business, or a problem which has been viewed from afar. If you start a business telling the customer what their problem is, as opposed to being proactive in determining their problem, your business will not go far.

Validating the demand for your product is the most important thing you can do. More important than features, your team, design, pricing, etc. Now, this is not to undermine the entire business process, however, if you are not solving a legitimate problem - however good your intentions are - the business will struggle to succeed. 

You are in the process of creating impactful businesses which serve a social and environmental purpose, but that doesn’t mean the project can ignore the realities of business.

You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible.
— Paul Graham

Define your customer segments and target market

So how will you know whether you are solving a legitimate problem? The trick is to test this with your customers, but this of course means that you will need to define who your customers are.

It is important not to think that everyone is your customer or you will design a product that a lot people kind of like. You want to do the opposite - you want to design a product that a few people love because if people love your product, they will promote it and help to drive growth.

You need to define your target market, the group of people who you think have a problem that you will be able to solve.

Exercise: Brainstorm all the different groups of people who you can think of who might be a customer of your product. Write a story for each group about how they experience the problem in their daily lives and how your solution can change their lives for the better. Identify which of these segments you think your idea would best serve.



Problem identification

Once you have identified your target market, you need to observe and discuss with them the problem that they are currently facing. Figure out whether people in your target market tend to gather and where they tend to experience the problem you believe they have. Then go there and watch them experience their problem.


We’re going to go over interview techniques in greater detail next week but it’s worth starting to interact with your future customers right a way. So ask these people about they problem they are experiencing. Don’t jump straight in to offering your solution. Instead, just ask them open questions.

For example, if you are trying to solve the problem of people allowing food to go to waste you could ask whether your interviewee ever had to throw out food.
