The filter
Pain × audience × reach × retention
What to expect
Honest guidance before hype.
No invented certainty
Every recommendation shows its assumptions, constraints, and likely tradeoffs.
Built around execution
Leave with a narrow test and a next action—not another folder of vague inspiration.
The NarrowSpark method
From “what if?” to a testable business.
A compact workflow for choosing a proven pattern and adapting it to the people you can actually reach.
Choose a proven model
Pressure-test the fit across micro-SaaS, vertical AI, productized services, visual commerce, and niche communities.
Build a distribution loop
Match the product to channels where its audience already gathers, then turn every launch into a repeatable experiment.
Pattern library
Start with models that already make economic sense.
Compare micro-SaaS, vertical AI, productized services, visual products, and niche communities by speed, margin, retention, and channel fit.
Specific recurring pain
Reachable narrow audience
Repeatable acquisition loop
A reason to stay or return
