If you can aggregate data that is otherwise hard to find and put it in an easy to use format, businesses will pay big bucks. My last company paid $2k a month for a daily feed of coupons and deals from over 200 sites (e.g. Groupon, LivingSocial). There is also https://www.aggdata.com/data https://www.aggdata.com/data which found a niche selling lists of company locations (e.g. the addresses, phone number, etc for every Jiffy Lube in the U.S.). They have a premium option which gives you access to all their data sets for a monthly fee.
