Your network is going to help you with this 10x as much as random matching would. I doubt random matching is even very successful, compared to organically finding a partner.
Ask around, see what people in your network know about folks who are building new things. They may even have ideas about folks who would build something if the right partner were to help them.
I don't think it's 10x. Your network is likely to be limited. Coworkers, buddies from school, friends of family? When you filter out all the ones with careers/no interest in starting a company, and then the ones you don't want to work with, you think you're left with highly relevant matches?
