Before
Solo founder idea validator with AI
After
BSolo founder idea validator with AI for one named user, reduced to the smallest paid wedge and grounded in observed demand and a costly current workaround.
Per-question score table
What's the strongest evidence you have that someone actually wants this?
Tight demographic, clear background, specific runway, narrow product category — testable.
What are your users doing right now to solve this problem, and what does that workaround cost them?
Pain is real and quantified, but the buying behavior link is unproven.
Name the actual human who needs this most. What's their title and what consequence do they face?
Real tailwinds named, but no evidence behavior has actually shifted yet.
What's the smallest possible version of this that someone would pay real money for this week?
Scoped tight, shippable, clear scope boundaries, realistic timeline with buffer.
What surprised you when you actually watched someone use this without helping them?
Hope-based distribution, no named founder, no fallback channel, untested message.
If the world looks meaningfully different in 3 years, does your product become more essential or less?
Numbers are specific but the leap to Series A at $7.6K MRR is delusional.
