In startups, they say you should always start with FFF: Friends, Family, Fools.
Look around you; who among the people closest to you is interested in the problem to which you offer a solution or who can simply support you personally. First, turn to them for help.
Also, remember that weak ties are the ones who actually help us find new opportunities - jobs, funding, etc.
Weak ties are people you know and meet once in a while (not, for example, like your best friends). Therefore, they have different experiences and different connections and can act as bridges when you are looking for new opportunities.
They are the people you meet at school; friends who go to class with you but with whom you do not communicate much; friends of friends who you often meet on each other's birthdays; friends with whom you regularly chat online but don't interact much face-to-face. You can reach out to all of them, tell them about your idea, and ask for their support.
