The baseline stance for tech startups is wanting to solve a problem in the world and profiting from the value that provides. And thankfully, most of the time, those motives don't conflict. Even a mundane business like my local grocery store solves the problem of a curating a selection of food producers, buying in bulk to ensure a sustained sustained supply at a reasonable price and make it available to me close to my home. That is a tremendous value! And for that they make their markup. They aren't necessarily solving other social problems like food scarcity or maximizing nutrition or whatever, and instead focus on what their customers want to buy, those that can pay for it. But there still is a meeting in the middle of value being created.
