Get new users by submitting your landing page to design showcases.

If you've got design chops, you can garner interest in your product by showing off its design. Get traffic and signups by submitting your site to UI showcases.

Harsh Vijay of ruttl got a big spike in traffic and a couple of new users after submitting his website to One Page Love. Design showcase sites like this and Dribbble are unlikely to be the cause of hockey-stick growth, but they can help while you're searching for your first ten customers — especially if you hit the front page like Harsh did. Of course, you'll need a killer design for that. This approach will work best for products that are geared toward designers and developers, since that's the primary audience that you'll reach.
