As someone in a similar boat, my advice would be to start working on just driving attention/traffic to each one and see what the market tells you. It doesn't matter than your more recent idea is not as far along, there are lot of opportunities for lead generation outside of actually using the product (scorecards, waiting lists, etc...)

It doesn't matter how great either idea is if you can't get people to look at it. Focus there.
