It is so nice seeing good things happen to good people. In this case, brothers Saulius and Aidas Dailide found success on the Mac App Store.

[ad#Google Adsense 300×250 in story]The brothers are behind the popular image editor Pixelmator. According to a post on the company blog on Tuesday, Pixelmator grossed $1 million since the Mac App Store launched 20 days ago.

“Such an amazing success feels fantastic,” wrote Saulius. “Thank you so much for your enthusiastic support.”

In an interview with The Loop when the Mac App Store launched, Saulius said that they were fully committed to the Mac App Store. In fact, they decided that it’s would become their exclusive sales channel.

Certainly a risky move, but 20 days later, it seems to have paid off.
