Your LinkedIn link for your lead developer's profile appears to be broken, it took me to an error page stating the profile is not there. Ironically, the broken "feature" of your proposal is the exact one that should help you assure investors that you're not scam. Better fix it asap
There was an extra trailing slash at the end of the link. Can someone please try it again to confirm it is fixed? It's working for me.
It is working now, thank you for fixing it, I accessed the link from my phone, so it's quite difficult to spot the error on your link. Does other team member also has linkedin?
