The closed beta launched today. Lots of work and gratitude for so many people that gave encouragement along the way!
The most important thing that I learned was to (1) discuss specs (2) write them down , and (3) pick a deadline. And when obstacles occurred, we reduced the specs, but we made the deadline.
I couldn't be more proud of the team or happier with the result. None of this would have happened (nor the idea itself) without the inspiration from the community here at IndieHackers.
