I had my first two customers sign up for a paid plan over the last week. I had been running ads for the last few weeks to experiment with various keywords and see if I could do some demo's for the product and see what kinds of questions would come up about the system. One of the new customers came through the ads I believe (but not immediately, so I was not able to track their conversion).
The other customer came through a connection with one of my other apps. They explored my website and ended up signing up for the platform after that. I was a bit surprised, but I won't complain.
It does make me think more about cross promoting the product with some of my other tools to get it a bit more of a jump start. I will have to continue thinking about that.
