We run a big online restaurant guide in The Netherlands.

At the beginning of 2009, our income from AdSense (our main source of income) halved overnight and later dropped to about 25%. We had a little bit of money in the bank, but not enough to survive for more than a few months.

We immediately focussed on finding and developing alternative sources of income and those sources have now become our main sources of income and have enabled us to grow a lot.

Without that crisis, we probably wouldn't have grown as much as we have.
