Communication is the key when you're starting a new service or launching a new product. Yet it often starts too late and the process, even in a less advanced way, could bear more fruit if started earlier.

Social media are a good place to start, YouTube promotional videos as well as newsletters, drawing games... To an certain extent only as it may still be early to mass communicate on your idea.
That's where demos prove efficient. A short demo of a product in development proves much more effective than emails on a product that's not finished yet. Tell your friends, co workers, interested parties to come in for a new demo and show them you've made progress since last time.
Engage discussion and get feedback, you'll be surprised how effective that is!
