The Outcome, in 4 numbers
The 90-day system used by 10,000+ founders on IDEAPROOF
Distilled from real platform validations between Jan 2025 and Mar 2026.
The 6-Step Framework
The exact sequence that compresses 12 months into 90 days
Problem proof
10 customer interviews using the Mom-Test script
Demand test
Landing page + ads with quantitative kill threshold
Pricing pre-sale
Charge before you build — 3 conversion patterns
Smallest paid v1
30-day MVP using the no-code stack winners use
First-customer playbook
Onboarding script + retention triggers
Repeat or kill
Cohort-2 decision rubric with explicit go/no-go gates
Most founders skip Step 3
Surveys are a trap
The 7-day kill rule
Stated interest is not revenue. Pre-sell cohorts hit first €1k in 7 days — Build-First cohorts take 11× longer.
The Validation Arc · 2010 → 2026
Why founders stopped building first — and started pre-selling on day one
Build-First Era
Engineers built for 12 months in stealth, then discovered nobody wanted it. 90% failure rate baked in.
Lean Startup
MVPs, interviews, pivots. Better, but founders still confused stated interest with paying customers.
Pre-Sell Native
Landing page + deposit + pre-paid waitlist before a single line of code. Revenue-first validation in 7 days.

Validation outcomes by approach (% reaching first €1k revenue)

What Actually Works
3 tactics that converted. 3 that wasted weeks.
Worked in 2025–26 cohorts
Landing page + €1 deposit produces real demand signal. Refundable, but only 4% of buyers ever request the refund.
10 structured past-behavior interviews surface the real pain. Generic 'would you use it?' surveys are noise.
Posting in 1 hyper-specific community beats Product Hunt for paid conversion by 5× in cohort data.
Wasted founder time
Survey respondents say 'yes' to everything. Self-reported willingness-to-pay correlates near-zero with actual purchase.
Founders who skip demand testing and 'just ship' kill the product within 6 months of launch in 87% of cohorts.
Free users churn at 9× the rate of paying ones and provide misleading product feedback. Charge from day one.
Founders skip Step 3 — and pay for it
Surveys are a trap
The 7-day kill rule
Sample outcome spread
Each outcome: original idea → demand test → result → month-3 revenue.

Where the playbook-style founders are operating
Highest deal sizes, dominated by B2B SaaS and developer tools
Highest 90-day-to-revenue rates — smaller TAM but faster validation loops
Fastest growing cohort — India, SEA, LatAm solo founders building for global English buyers

Built for shippers, not strategists
Stop theorizing. Start charging.
Every chapter ends with the same prompt: what test do I run before Friday?
Validate demand before writing a line of code
Landing-page, ads, and survey templates that surface real intent in 7 days — including the kill thresholds that mean you stop.
Steal the 30 conversion scripts founders actually use
Cold email, LinkedIn, customer interviews, pre-sale calls — copy-paste-ready, with the response rate each pulled in the field.
Run the 12-week sprint calendar
Day-by-day plan with weekly stop/go gates so you cannot bluff your way past a failed validation.
Test pricing the way it actually breaks
Pre-sales, decoy tiers, urgency anchors — with case studies of what converted and what flopped at first cohort.

Why this isn't another Lean Startup re-explanation
Operating manual, not philosophy
The exact scripts, templates, and gates. Zero filler about why validation matters — you already know.
Kill-criteria on every step
Each phase has a numeric threshold. If you fail it, you stop. No 'pivot forever' purgatory.
Day-by-day calendar
12 weeks mapped to specific actions. Print it, tape it above your desk, follow it.
50 real outcomes, decoded
50 anonymized validation runs from the platform. Original idea → demand test → result → month-3 revenue. The single best chapter for pattern recognition.
