| A lot of people will suggest building a landing page / MVP to gauge initial interest, but I would start even before that: Don't spend any more time than necessary on something that you don't even know is actually viable. However, you need to find out if potential customers are excited about your idea. To find out whether your target audience is interested in your idea, I suggest the following validation process: * Write down a) the problem you're trying to solve and b) your solution. A lot of ideas may sound awesome while they're in your head, but that might change once you transform it from an abstract concept into 2–3 sentences. * Create a questionnaire based on your idea. Make sure to ask questions relevant to judging whether your idea might take off, such as "How often are you facing this problem" rather than "Have you ever faced this problem". Use a tool like SurveyMonkey or Typeform to put your survey online. * Identify people in your target audience. This is hard. Don't simply email the survey link to your friends - because of something called "Interviewer bias", your friends will rate your ideas more favorably than the general public. Also, it's highly likely that your friends aren't actually in your target audience. I run IdeaCheck.io[0], where we generate a questionnaire based on your idea and use a panel of respondents to gather direct feedback from your actual target audience.
