Well reaching out to them for one. There are people known as angel investors. They invest money into smaller projects that need funding. I would reach out to them if your idea is something that would benefit them. As well, reach out to other companies that fit your idea.
One other thing, campaign your idea, show it around. Tell people what it is capable of and maybe some big company will take notice.
It is about community, users, and suppliers of goods and services helping each other out sharing ideas.
The basic idea is to create a place where people can come to learn and explore what is needed to start that side gig or that small business that you have always wanted. We also want people that have already taken the step to show their stuff, offer their services.
