A startup app idea is only as good as the first ten users who say "I need this". The fastest way to find them is a clickable prototype with a shareable link — not a deck. Each idea below is a niche where people already pay for clunky tools, with room for something simpler.
Use the prototype to run five-minute user tests, collect reactions and comments, and iterate with the remix button.
