Design the first five minutes
Get one person to the payoff before you build anything else.
My tool does <this>. The moment someone "gets it" is when they <the payoff>. Design the shortest path from landing on the page to that moment. - What is the fewest number of steps? Can any be removed entirely? - What can I default, guess, or pre-fill instead of asking? - Where does someone give up, and what do I do about it there? Tell me which of my current steps exist for my benefit, not theirs.
Every field before the payoff is a place people leave. Sign-up walls are the most expensive thing you can put in front of a tool nobody has tried yet.
