Yep. I was involved in a local 'pitch your startup to a room full of investors' conference. Guess who 'won' the contest and had everyone talking about it? The three college kids with a mobile app that flat out said, we don't need your money, we're profitable, we have big deals with major corporations and we're growing fast. We're here to work on our product pitch to people outside our niche for continued growth.
Did you not read the article? They want to expand, being profitable does not mean they have the revenue to expand as much as they'd like.
Sure they can be like any startup and get some nieve devs to join up with the whole "We're doing big things and can become huge, you can be a part of this, and be millionaires!". But they'd probably rather give their devs what their worth.
