I followed a "work behind closed doors and make big releases" during the first 5 years. It didn't work well. Then, I followed the continuous improvement method for the next 5 years. That also did not work. Finally, I found my own approach to development in the last 2-3 years. And it is working amazingly so far. We have had 900K signups in 2017.
