The first thing you should worry about when you start a software project is how your product can be delivered to end-users in an automated way. Right after you managed to create a skeleton and make it "work on your laptop," start configuring the deployment pipeline. Only after it's done, demonstrate your product to your testers, partners, investors, customers, etc. Don't tell them that your product is in GitHub and if they want they can check it out themselves. This is very unprofessional. Make sure they can touch the product where its end-users will see it when it's fully ready for the market launch.
