Hi neolight - since it's the end of the year/start of the new year a lot of advertisers are just getting their budgets ready for 2016. So a lot more tier3 campaigns will be coming online very soon, however we do support over 200 countries and always do our best to get the highest payouts for these markets. If there are specific countries you are targeting we can definitely focus on getting those campaigns in as well or if you need to support a wide array of tier3 countries we can definitely do that too. Feel free to message us or sign up and submit a support ticket and we can get you setup! Best, AWM
