What Is Your Favorite Framework To Generate Business Ideas?

This list covers practical frameworks to generate and vet business ideas for founders, product managers, and solo builders seeking structured approaches. Use them to spot unmet jobs, map customer value, assess markets, and ideate improvements; include software and tech-enabled services, early-stage validation workflows, globally applicable methods, and modern internet-era theses; exclude pure execution checklists, niche academic models with limited startup relevance, and tools that only address post-PMF scaling.
