Before you unlock: common questions about this idea

Honest answers based on what the dossier actually says. No hype.

The upside might be too small to bother.
The Fermi model gives a year-1 take-home estimate, labeled as Fermi math. If the number doesn't justify your time, the dossier itself tells you so.
Why pay $5 if I can just ask ChatGPT?
ChatGPT will give you a starting point in 2 minutes. The dossier is 4-7 pages of structured product strategy: ICP by role, MVP scoped, 30/60/90 plan, financial model, outreach drip, and risk memo. If you've tried to outline a product with ChatGPT, you know the difference.
Will the idea actually work?
We don't know, and neither does anyone else who sells 'ideas'. What we promise is that the strategy is internally consistent, the math is checked, and the technology is buildable today. Most ideas in any portfolio fail; the survivors had taste, hustle, and timing.

Yr1 ARR (high)
$520K
Yr1 take-home
$-2K

If you close 2 projects/month at $8k average that's $192k revenue and ~$105k gross profit - but with an 18% chance of actually getting there in year 1, your expected take-home after investment is roughly negative.

Estimates only. No live customer revenue claimed. The full model with editable assumptions is in the dossier.

What you'll see in the dossier

  • Buyer: the named ICP, the workflow, the budget line, the title that signs the check
  • Pain: the specific failure mode they hit today, in their words from skeptic-memo research
  • Why now: the market shift that makes this idea possible in 2026 and not 2022
  • MVP scope: a 5-page site map + the first 7 build tasks ranked by leverage
  • Stack recommendation: what to build it on (Wes-stack-aware: cPanel, Caddy, Postgres, iOS Swift, Remotion if needed)
  • 30/60/90 launch plan: what good looks like at each milestone and what to drop if you slip
  • Pricing model: three positions tested against the same buyer (annual/monthly/per-seat)
  • GTM channel: the one channel to win first, with the angle and the first 50 prospects
  • Outreach pack: the LinkedIn message, the email subject lines, the cold-call script
  • Email drip: day 0, 2, 5, 9, 14, 21 with full copy
  • Likely objections: the seven you'll hear most, with handled responses
  • Risk memo: what makes this idea fail honestly
  • Fermi financial model: three scenarios with the assumptions exposed and editable
  • "What we'd implement for you": the operator-partnership scope if you'd rather hire than build
