Not in ads but I know they are quite effective. Most startups can attribute their growth to the effectiveness of digital advertising. Robinhood was driving app installs for $10 each while E*TRADE and Ameritrade were paying $1000 per customer.

Most of that VC cash startups raise is spent on marketing. I don’t understand why people have such negative perception of ads especially on a VC run news site. All the ycomb companies drops tens of millions on digital advertising.

Thanks for your considered response to my snarky comment. Personally I don't mind plain ads which are simply a commpany advertising their product/service on a billboard etc, what I find unbelievable in the digital era, is the extent of the intrusion now on finding out everything about people to market to them better (which I'm not even sure if having more data on someone has been proven to produce better results). Its really the data broking side of it - if that went away I'd have no issues.
