Percentage growth comparisons between companies of different sizes are meaningless. When you're small you can 'outgrow' anything substantially larger than you with ease. It only starts to count when you're of equal size, reasonably big and outgrowing your competitors by a significant margin.
Any startup will grow 1000's of % in the first couple of years, that's the easy part, you get that growth for free. After all 10 * 500 users is 5000 users, 1000% growth. But it doesn't mean much.
Sorry ?
