That's awesome! You might also want to rethink what your market is. Is your users going to be engineers who build web app for their company, engineers who build their side projects, some developer-designers or maybe some technical product managers/product engineers? You can still catch all of them eventually, but in the beginning focusing on one or two groups might help quickly get more users and also help on morale.

Yes, you are quite right. And I already decided the following. Acting as market we will be focusing on engineers who build web apps and freelancers. And as a company with own product we will provide development teams with something like component generator service (installed on internal server) for Structor - this is for enterprise customers.
