What are some products you found here and use for your business?

Hey everyone, I am curious about products that were found here and are used by anyone for their business? I am working on something and I am still quite a bit away from launching here. I would like to know how other products have been received. The obvious big name products surely do well but they were probably marketed in lots of places. It would be interesting to see products that are lesser known but have retained users from Product Hunt.
