I have used found.ee and it's a great tool for all the tasks that are mentioned either its geo redirection of links to the shortening or using custom domain! it's all easy as a pie. Foundee really deserves an appreciation.
However, one area of improvement is the font size and font weight, Foundee need to address this issue, at some spaces the font-weight is too low that it becomes hard to read the things. And this is not just limited to some particular page, its for all pages. This was just some constructive opinion to help the community.
Otherwise, Foundee, no doubt is a great Freebie. Loved the hard work of the creators. Keep going.
