I had the same problem. Transitioning from having built the thing to asking people to pay for it felt quite awkward at first. I feel a lot less awkward about it now that I do have paying customers who are happy with it and use it daily. It feels great, when someone who isn't legally obliged to, pays you for something you built because it makes their work easier.

>> how do you find your customers? Especially the enterprise ones?

Haphazardly and slowly thus far:) A couple of enterprise customers actually found me, but my own reach into the enterprise world is not really substantial. Some of my customers are consultancies who work with banks and such so I started talking to a few of them about partnership. It's not something I can completely outsource, but partners could certainly help a lot. We'll see how it goes.

Building an audience is a good idea, although it's easier to do if you have something to show people, I think. I'm not a businessy person (maybe I become), I just enjoyed building it, so that's what I spent time on. That's not to say that I wasn't hoping to make a business out of it, I certainly was, from very early on:)
