Not bad, $2.7m in sales over a year, 8 people, gives you around $350k per person. Presumably they're not sharing equally, but that's still not a bad return for the first year on the market. I wonder how many person-years it took to build and market... I would assume less than 8, so they seem to have done pretty well for themselves.
Nearly every one of their apps have gone #1, not to mention all their MacHeist revenue, so their small team is doing really, REALLY well on an individual basis since they mostly do a profit share between teammates.
