We know everything about our own tooling; we use it daily and obviously are the best at supporting it. There are 100s of 1000s of services online and we cannot support or guess them all. If you require integration with one, please drop us a note; it is very possible we will do this for free if we see the necessity of the integration. Otherwise we might request a fee for doing this; in vertical markets, we might even partner up for sales and marketing in this vertical on a revenue-share basis! Anything is possible, just drop us a line.
