That's great! :D
It's good to know that a software company can still turn a profit without screwing it's users. :D
Please don't make the same mistakes caused by Makerbot selling out to Stratasys, and screwing over the Thingiverse community.
Also, remember that you and the founders won't be at that company forever, so you may not be the people doing the screw-overs, but unless you directly address this now, your browser won't get the traction that it could get.
