Before you giving your money to people, you need to know who they are and what experience they have. If developers never worked in medicine, finance or journalism fields, they probably won't make any innovations in these areas. If they don't have the experience in building a business, the project can fail because of the inefficient management.
You can find all information about the founders on the landing page or in the whitepaper. You will also see links to their profiles on LinkedIn where you can check the previous experience and achievements of the team.
The company has to communicate with investors: post news and updates on Facebook, Twitter, Medium or their blog, have chats in Slack and Telegram. The active communication doesn't guarantee the success of the project, but it enables you to keep track on the project.
