Neat, you got some validation! What about customer validation? Is investors or people are talking about your competing company? Note down the sources so you can talk to them, especially if they are your ideal market. It means you can find out what they'll pay for and/or market to!

Next step is to go through your logged or memorised history with the cofounder. How do they treat people? What's their style? etc. Look for their strengths and weaknesses.

Now, if you believe that you have a better direction after all this, then you'll know competition much better than most people. eg Microsoft doesn't understand due to the paranoid nature of Google's NDAs for example.

Sorry, but your idea is one direction and pretty useless on its own. There's many ways to evolve your idea though. Investors especially love executors.
