From hammet - the man behind the castle project "Our first goal is to make an agile project management web app. Why? We are not happy with the apps we have been using. They clearly are clueless regarding usability, and the pricing is unreasonable - not to mention the drug dealer selling model. The one that has a very decent UI is just not flexible. Also, I’m not a total fan of SaaS model, so I’d rather host my and my clients projects and important data."
