Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
The idea solves a specific pain but the market size and monetization potential are limited, lowering overall value.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
There is a clear user need and a straightforward solution, but competition from free content and low monetization reduce attractiveness.
Viral Frameworks

The concept fits a niche DIY market with moderate demand and feasible development, but scaling and differentiation are challenges.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
The idea is simple and addresses a real problem, but lacks strong defensibility and a large, paying user base.
