I dont see yet what you project is about. You have a advertising network. But instead you being the middle man between advertiser and publisher, they can connect directly? And you get a fee for making the contact?

You mention personalized ads as free as a the internet. Isnt that risky when someone creates such a personalized ad that installs keylogger or something? Is there no control?

And at the end i dont understand what you need $50k for. You mentioned you bought a domain for $35k, the website is ready 90% but i dont see what its needed for. Besides i dont see the worth of such a high priced domain while a longer, brandable name could do the same too.

On top... you claim the userbase is already huge... why not simply reinvest the profit from there? Im not sure yet why you need additional funds now.

You didnt mention the url as long as i didnt miss it.
