To me profitable means making more money than it costs to operate. I personally wouldn't count my own time in that equation until I officially draw a salary from it. So if I spent 100 hours making something and spent 5 hours a week maintaining it and it cost £500 a month to run, and the revenue was £501 a month, to me that's profitable. Now obviously it's not profitable enough to keep it in its current state as 5 hours of my time is worth more than £1 but it is worth the time and money investment to make it bring in more revenue.
