This tells it all. Looks like they were developing it for at least 1 year, I'm guessing they had something to the tune of 4-6 people (if not more) actually working on the development. Still, if they keep up this revenue for a year, it could end up being some very nice returns. Will they really be selling ~$1m a month, or will it taper off soon?
