Revenue of what?

The Qt Company (QTCOM). They're publicly traded, so they have to publish yearly financial statements.

Their employee count has also doubled, which is why they're not making any profits despite the revenue growth.

Edit: Ah, you're pointing out that only 25% of their revenue is commercial licenses, while most of their revenue is consulting. I don't know if that's really such a big deal.

You're getting close ;-)

If you know enough about their business model to state that it doesn't work, then you know the answer to that question. So why do you ask, what are you trying to say?

Just have a look with what they earn money. The other stuff is just holding on to an illusion.

They earn money with Qt, an open source library.

No. Look closer.
