Wait, it was making 6K a month and they sold it for 30K? That is crazy low.

6k revenue (+maybe some percentage here and there), and paying for two employees.

How to take advantage of people. Like Peter Thiel says. How to take advantage of dumb engineers who only know how to work hard.

if the source code is relevant and useful, that could be worth the price in itself... like Google/Facebook buying companies just to get the employees.
