Spend the pitch on the problem, unless the problem is obvious
Founders love their solution and tend to talk about it first. Listeners cannot value a solution until they feel the problem it solves.
For the most effective pitch, focus 80% on the problem, 20% on the solution.
Dave McClure, who founded the seed fund 500 Startups in 2010, has heard more pitches than most people. His complaint is familiar among investors: founders open with the product, walk through its features, and never establish why anyone needs it. The listener is left to guess at the problem and usually guesses that it is small.
The 80/20 ratio corrects for that. A problem explained well does most of the persuading. If an investor understands that small shops lose hours every week reconciling payments by hand, and that there are millions of such shops, a reasonable solution sounds valuable almost before it is described. A brilliant solution to an unclear problem sounds like a toy.
A strong problem section is concrete. It says who has the problem, how often it happens, what it costs them in money or time, and what they do about it today. The last point matters most, because a clumsy workaround in wide use is proof that people care. If the section ends with the listener nodding, the solution slide needs only a few sentences: what the product does, why it is better than the workaround, and a quick look at it working.
There is a risk on the other side as well. A pitch that spends too long on the problem can leave the impression that the founders have thought more about the pain than about the cure. Investors also want to judge whether this team can build the thing, and a short, confident demonstration often does more for that than another minute of market sizing.
The ratio is a teaching device, not a formula. It fits early pitches in unfamiliar markets best. When the problem is already obvious to everyone in the room, such as slow international payments or expensive textbooks, spending most of the time on it wastes the meeting. Later-stage pitches should shift toward evidence, meaning users, revenue and growth, because by then that is what the listener is judging. The lasting lesson is the order: problem first, then solution, then proof.
