Frequently asked questions
- What is the Idea Database?
- A structured catalog of startup and business opportunity areas. Each entry includes a problem, target user, solution, industry tags, difficulty, and multi-axis classification — not a thin listicle.
- Are community discussions mixed into this database?
- No. Community discussion themes live only under Community Discussions. The Idea Database stays focused on curated general opportunity areas.
- How do I filter ideas?
- Use industry, difficulty, technical depth, quality (flagship), and search. You can also open Industries or Find Your Own Match for guided browsing.
- What do Beginner, Intermediate, and Advanced mean?
- They estimate implementation difficulty: capital, skills, and time. Beginner is lighter to start; Advanced and deep-tech usually need more expertise or resources.
