Well I can fill 14 hours a day with client work too. But when working for your startup you calculate the minimal income you need and only spend the amount of hours on a client to earn it. The rest of the time is spent on working for your startup. When I was co-owner of a isv our main income in the beginning was consultancy for clients. In addition we developed our product and used the spare money to hire additional developers. The consultancy work made sure we had a minimal paycheck at the end of the month which would pay our mortage and the bills. Maybe this model is not sustainable anymore with being quick to the market and bead competitors on speed. But it worked in that period of time.
