Idearate

This sounds like a great tool and I'm looking forward to seeing what you build. The mobile web experience of the current site appears broken, however.

We are a team working at WATTx, a Berlin-based company builder. As a company builder, we are regularly evaluating ideas and assessing their viability. We realized that too often, we put too much effort into an idea that ended up not working out. When we reflect on those ideas, we understand that we had too many assumptions. ​ During a hackathon at WATTx, we challenged ourselves to solve this problem by creating a tool that helps people focus on clarifying all assumptions. This product will prevent us from putting effort into ideas that have too many blind spots.

Cool! I always have tons of ideas and it would really help to have a tool that allows me quickly to share my idea and brainstorm it :-)
