Inverse funnel theory and astronomy. Inverse funnel theory The inverse funnel theory is the idea that a product makes it easy for early users to adopt it, while allowing customizations, add ons, or advanced strategies, that keeps advanced users interested in the product. Some notable examples of this are: All in all, the premise of implementing the inverse funnel theory involves keeping the learning curve low for early users, while keeping these users engaged/challenged by introducing them to harder concepts as they familiarize themselves with the product.
