I've read a lot of pitches through different websites that are also looking for angel investors but they're careful with how they propose their projects. Also, as mentioned your website isn't finished yet so there's nothing to market, there's nothing to advertise and why find people who will promote your project if you have no actual product yet?
It's been seven days since he created this thread I checked his platform and still the same nothing on it, the guy is not truthful, I don't know what is his idea of marketing but this is bad marketing for his incoming platform.
Too much eagerness when you can't show anything. If he ever launches his platform it should be good and competitive to erase our doubts that the people behind your platform are just newbies who are in a hurry to make money.
