I&#x27;ve noticed tiers of understanding of ad tech. Some people have never run campaigns and critique gaming companies for focusing on acquisition instead of product.<p>Others run a test and fail (including early days of Dropbox).<p>Others have $100K&#x2F;mo budgets and ads are the basis of their entire business. Jamie has built tools for the high end, and now anyone can use them. Fuck yeah.<p>Jamie and I first met in YC W08 -- seems like ages ago. He&#x27;s one to watch.
