Valid signal = real task completion, reuse, or pay intent — with observe + continue/stop.
01
Create a landing page with a clear value prop and email capture.
Observe
Number of signups, click-through rate from the headline.
Continue
At least 10 signups in one week from targeted communities.
Stop
Fewer than 5 signups and no engagement in comments.
02
Post the landing page on Hacker News and relevant subreddits (r/productivity, r/freelance).
Observe
Comments, upvotes, and direct feedback on the concept.
Continue
People express interest in the specific pain of forgotten tasks.
Stop
Most comments say existing tools already solve this.
03
Interview 5 signups (or commenters) about their current workflow and pain points.
Observe
Specific stories of missed tasks, costs, and workarounds.
Continue
At least 3 describe a recurring painful scenario.
Stop
Interviews show no strong pain or they are satisfied with current tools.
04
Decide whether to build a prototype based on interview insights.
Observe
Clarity of the wedge and whether the value prop is compelling.
Continue
The prototype idea is focused and users express willingness to try it.
Stop
No clear differentiation or users are not willing to test.

Should I keep building this idea?
Worth running a landing-page smoke test to gauge interest, but demand is unprove

Who is this validation for?
Freelancers and independent consultants juggling multiple client projects.
How should I read the score?
Current OPC feasibility score is 5/100. It is an AI-assisted executability check, not a market guarantee. Low scores mean “prove demand first,” not “never build.”
07 Evidence & boundaries
Demand evidence summary
No external or user evidence; only a hypothesis based on common productivity pain.

Model hypothesis
People who juggle many tasks may forget some; a tool that nags until done could help.
Known facts
Keyword exists on Hacker News.
Task management is a crowded space.
