Skillful pitching… is a necessary, but not sufficient, part of raising capital. More important are the realities of your organization: Are you building something meaningful, long lasting, and valuable to society?

If you truly don't have competition, then zoom out until you can define some. Competition can be as simple as the reliance on the status quo, Microsoft (since at some point Microsoft will compete with everyone for everything), or researchers in universities. Pick something, because saying you have no competition at all is a nonstarter.
