I’ve been chatting with an early-stage founder and providing feedback about his pitch deck. He’s sharp and a go-getter, and I enjoy working with him. He’s looking to raise a seed round from a venture capital firm and wanted my thoughts, since I’ve been inside an early-stage venture capital firm.

One of the things I’ve been questioning is the problem he’s trying to solve. He wasn’t stating it succinctly—he alluded to it, mentioning other problems as well. It was up to me, the reader, to reach the correct conclusion about the main problem he’s solving. I’d talked to him, so I could do that, but what about the investors who see a few pitch decks a day and would see his pitch cold? They won’t take the time to try to figure out the problem; they’ll just say no and move on to the next pitch deck.

Businesses exist to solve a problem for their customers. Customers pay for that solution if it provides value to them. It’s that simple. The customer’s problem is the foundation of the business. Solve their problem in a way that customers value, and they’ll pay you for that value. If you can’t articulate the problem clearly, that failure cascades through all aspects of the business and makes everything harder. Raising money and closing customers is harder, and even recruiting may be more challenging.

Understanding the one main problem you’re solving and communicating it clearly is harder than it sounds. If you can’t articulate your problem in a way that people instantly understand (even if they disagree with it), consider spending some time refining it and getting feedback until you nail it. Getting this right as early as possible will give you a north star that will make decision-making, fundraising, and a host of other things easier (not easy!) down the road.
