I am often asked this question by start-up enthusiasts - when will company X turn profitable? And if they will, what will be the levers that will make it profitable?
The answers, however, is far more complex than the question. There are different visions that co-founders have for their companies. Ideally, any business should target reaching a milestone in terms of scale, and then just focus on becoming profitable. However, the conflict of scale v/s profits eats it up.
