From Idea to Online Business: 5 Steps

  1. Find complaints: Search BigIdeasDB for real problems in your target niche. The more people complaining, the bigger the opportunity.
  2. Check revenue proof: Look at our startup database to confirm someone is already making money in this space. Competition means demand exists.
  3. Pre-sell before building: Create a landing page describing your solution. If you cannot get 10 email signups, the idea needs work.
  4. Build the smallest version: Launch with one core feature that solves the main pain point. Do not build everything at once.
  5. Iterate with real feedback: Talk to every early customer. Their complaints will guide your product roadmap better than any strategy document.
