We're still bootstrapped and fairly small (< 25 employees including the founders). We've grown organically to about 1 million users since then. The feedback we've got on our submission back then gave us enough courage to go from just a pet side-project to a full time business, so Big Thanks HN! That day was one of the happiest days in the history of our business.

We really like using Moqups here. We've architected, wireframed, and sold some big projects because of it. :)

Thanks for letting us know! We're happy to hear that.

We've changed the product quite a bit in response to the huge projects that our users create on our design platform. Nevertheless, we've also faced quite a few engineering issues in respect to browser performance and real time backend data synchronization.

Its a wonderful tool! If you could shed some light on the stack used in the editor.

Thanks! It's mostly vanilla JS and the Ractive framework for the editor UI.
