Ship a Throwaway Tool to Harvest a Pre-Qualified List

Ship a Throwaway Tool to Harvest a Pre-Qualified List is a first users & traction tactic for getting your first users: Before launch the founder built a simple, deliberately short-lived adjacent tool for the exact buildathon crowd: it scored a user's idea or URL against the competition's official criteria and gave feedback. Over 100 people used it, seeding an email list of pre-qualified future users.

It's a strong fit for teams of almost any kind, and works especially well for New platforms facing a chicken-and-egg cold start. As a first users & traction play, plan for medium effort and expect results to arrive at a steady pace, all grounded in 1 linked primary source.

Why does first users & traction work for this?

It collects emails from people already pre-qualified by context and gets them invested before the main product even exists, which solves the cold-start problem.
