Balsamiq is a small software company I've heard mentioned from time to time but never really got my attention before. It sounds like lots of people have been paying attention and buying their product.

Peldi Guilizzoni has written this post looking back over the first 18 months of his company and the explosive growth they've seen. They've gone from being a one man show with no revenue in mid-2008 to a 3 person operation with annual revenue of over 1.5 million at the end of 2009... impressive.
