From my experience as a serial entrepreneur, there are several ways to validate your product idea:

- Create an MVP an show it to your friends and family

- Validate the idea on some online communities like Reddit (www.reddit.com)

- Cold-call some companies and ask if they have this specific problem

- Use an online idea validation service like IdeaValid (www.ideavalid.com)

- Find similar products which already exist
