It wasn't one of those ideas that I could code up an a sleepless weekend or even a month of development. It took the better part of 2 years, working on it about 10 hours a week, to plan and build GroupNews to the point where we felt we could take the covers off and show it to the world. We did exactly that a few days ago.
Part newsletter platform, part messaging app, we pitch it like this: GroupNews makes internal communication easy. It allows any group to collaborate on and publish beautiful internal newsletters in minutes, without hassle.
To me, the designing and building is the part that comes naturally and (relatively) easily. While there's plenty of iteration and new development I have planned, we have to now spend a lot more time on customer acquisition. We've got some early adopters in there trying it out, but it's still on the road to profitability.
Have a look if you'd like - I'd love to hear your thoughts.
