We spend a lot of time matching items in one list in another list...it's time consuming. Speaking with our fractional CFO, he said he also spends too much time match items in one list in another. So we built https://robomerge.com/ so you don't have too. It is free for now and allows for anonymous sessions created by your ip address, we will be allowing user registrations soon, and we also have an api in the works. Feedback welcome.
