Minimal viable testing: teleclasses and opt-in rates before full build

Before you build a full product, test the concept with the minimum viable version. For information products, that means teaching the topic in a teleclass or adding it as a session in a program you're already running. Watch the response. For online ideas, set up a simple opt-in page and track the rate. One percent opt-in tells you low interest. Ten percent is meaningful proof of concept. Fifty percent is strong market validation. Use free and low-cost tools — blogs, social media groups, forums — to measure whether people actually want what you're considering. You don't need a finished product to get real market signal. You just need the willingness to test before you invest.
