Balsamiq Makes 1.6 Million with 70% Profit in 2009
This is making me feel really inadequate -- Tarsnap launched publicly only 5 months after Balsamiq, but it's nowhere near Balsamiq in revenues.  (Possibly Tarsnap pricing starts at 300 picodollars/month rather than at $79.)Oh well, humility is good for the soul, right? :-)
