Getting customers directly is actually not the problem. The usual marketing and growth hacking tools worked quite well. Our problem is getting partners that refer customers. I don't mean affiliate partners but real partners that include our service into their service as a complement product. Potential partners happily include Google Maps and phone call back forms but shy away from using our service, even though it would make them money and could be really useful for their customers. The opportunities are there. We've spoken to a couple of promising partners but they a dragging their feet. If they would at least provide some feedback as to why they balk at using our service, that would be great. But that is apparently too much to ask for.
