Founder of Adbassador | Building a vetted advertising marketplace

About

I built Adbassador after spending too long dealing with shady guest post sellers and overpriced agencies. Now I run a marketplace with 800+ vetted publishers where advertisers can buy placements directly, see real metrics before ordering, and not worry about ending up on a junk site. Based in Carson City, NV.
