Sonardesign develops a platform for content creation for multiple device deployment which greatly reduces the cost and increases the time to market.
They have over 10,000 registered users and have done virtually no marketing (our Head of Marketing just started two weeks ago). They have been deep in development mode for two years because the complexity of a creation platform is quite high. Adobe spent years and millions of dollars trying to create a browser-based creation platform and had to abandon it because it wasn't working. Partly it was a timing issue but the biggest issue is the breadth and depth of technical skills required to pull this off is really high.
