How to Validate a SaaS Idea Before You Write Any Code

Short summary

A practical 7-step validation framework for solo founders that takes one weekend (12-16 hours) to determine whether a SaaS idea has real market demand. The process moves from problem definition through severity scoring, competitor mapping, and feasibility checks, with the core insight that willingness to pay is the only signal that matters—interest is free. Ideas below 9 on frequency×pain and with strong existing workarounds should be rejected rather than built.

• •Define the exact problem with named audience and pain; don't start with the solution
• •Score severity by frequency × pain (below 9 = reject, above 15 = pursue); workarounds are hidden competitors
• •Test solo feasibility in 4 weeks and get written verdict (Build, Wait, or Reject) before writing any code
