The 100 Challenge was born from watching too many founders pour time, resources and money into building startups that, frankly, nobody needed. Testing your big idea on a sample size of one (even if that one is your mum) isn’t problem-fit. Whether it’s the instant a spark of inspiration hits or you’re halfway down the road to changing the world, this is the most crucial step you’ll ever take.

The whole point of the 100 Challenge is simple: prove beyond doubt that a genuinely painful problem exists, then dig in relentlessly to discover which part of that pain really hurts. Only once you’ve mapped the true agony should you even consider what solution to build. Get this right, and every bit of energy you spend goes on something people will actually pay for.

Let’s get stuck in.
