The output is a pricing recommendation memo backed by both stated preference data and real-money proof — the only evidence investors and pricing committees should trust. [src6] ## Prerequisites - [ ] **Product or service description** — clear enough for a survey respondent to evaluate (1-paragraph description + 3-5 key features) - [ ] **Target customer persona / ICP** — who to survey and where to find them - [ ] **Candidate price range** — at least a rough hypothesis (e.g., "$29-$149/mo" or "$500-$5,000 one-time") - [ ] **Value proposition** — what makes this worth paying for vs. alternatives - [ ] **Stripe account** — API key from [Stripe](https://dashboard.stripe.com/register) (free — pay per transaction only) - [ ] **Survey tool account** — [Typeform](https://www.typeform.com/signup/) (free: 10 responses/mo), [Google Forms](https://forms.google.com) (free, unlimited), or [Tally](https://tally.so) (free: 100 responses/mo) - [ ] **Landing page tool** (for fake door path) — [Carrd](https://carrd.co) (free), [Unbounce](https://unbounce.com) ($99/mo), or custom HTML ## Constraints - Survey-stated willingness to pay inflates actual purchase rates by 3-5x — never use raw survey numbers as pricing proof. Only credit cards or LOIs count. [src5] - Van Westendorp requires minimum 100 respondents per segment; Gabor-Granger requires minimum 100 per segment. Below this threshold, confidence intervals are too wide to act on. [src1] - Fake door pages must include clear disclosure: "This product is not yet available. You will be charged $X as a pre-order and refunded if we do not launch by [date]." FTC compliance requires this. [src4] - Refund all fake door payments within 30 days if product does not launch — Stripe chargeback rate above 1% triggers account review. - B2B LOIs must specify: product description, price, quantity/seats, timeline, and buyer signature. A verbal "we'd pay that" is not an LOI. [src5] - Do not survey your own team, friends, or family — they systematically overstate willingness to pay. ## Tool Selection Decision ``` Which path? ├── B2C + want price range discovery │ └── PATH A: Van Westendorp Survey — Google Forms/Typeform + Sheets analysis ├── B2C + want revenue-maximizing price │ └── PATH B: Gabor-Granger Survey — Typeform/SurveyMonkey + demand curve ├── B2C + want real-money proof │ └── PATH C: Fake Door Test — Carrd/Unbounce + Stripe payment capture ├── B2B + want commitment evidence │ └── PATH D: LOI Collection — Outreach + LOI template + signature └── Full validation (recommended) └── PATH E: Survey (A or B) → then Fake Door (C) or LOI (D) ``` | Path | Tools | Cost | Speed | Output Quality | |------|-------|------|-------|---------------| | A: Van Westendorp | Google Forms + Sheets | $0 | 3-5 days | Directional — shows acceptable range, not purchase proof | | B: Gabor-Granger | Typeform + Sheets | $0-$25/mo | 3-5 days | Directional — shows demand curve, not purchase proof | | C: Fake Door | Carrd + Stripe | $0 + 2.9% per txn | 5-10 days | Strong — real credit card = real intent | | D: LOI Collection | Email + DocuSign/PandaDoc | $0-$25/mo | 7-21 days | Strong — signed commitment with price and terms | | E: Full Sequence | A/B + C/D | $0-$50 | 7-14 days | Highest — survey data calibrated by real-money validation | ## Execution Flow ### Step 1: Select Method and Define Price Points **Duration**: 30 minutes **Tool**: Spreadsheet Define 5-7 candidate price points based on competitive analysis and founder hypothesis. These price points anchor all subsequent research. ``` Candidate Price Points Worksheet: 1. Cost floor: $____ (minimum viable price covering COGS + margin) 2. Competitor low: $____ (cheapest comparable alternative) 3. Competitor median: $____ (most common price in market) 4. Competitor high: $____ (premium alternative) 5. Value ceiling: $____ (maximum justifiable by ROI or value delivered) 6. Aspirational: $____ (what you wish you could charge) 7. Anchor: $____ (highest price shown to make others seem reasonable) For Gabor-Granger: select 5 evenly spaced points between #1 and #5 For Van Westendorp: no pre-set points needed (open-ended responses) For Fake Door: select 2-3 points from the middle range for A/B testing ``` **Verify**: All 5-7 price points defined, competitor data sourced from at least 3 competitors. **If failed**: If no competitors exist, use cost-plus 3x as floor and 10x as ceiling. ### Step 2: Build the Survey (Path A or B) **Duration**: 1-2 hours **Tool**: Typeform, Google Forms, or Tally **Path A — Van Westendorp (4 questions):** Present the product description (2-3 sentences + feature list), then ask these four open-ended price questions in order: [src1] ``` Question 1: "At what price would [product] be so expensive that you would not consider buying it?" [open numeric field] Question 2: "At what price would [product] start to seem expensive, but you would still consider buying it?" [open numeric field] Question 3: "At what price would [product] seem like a bargain — a great buy for the money?" [open numeric field] Question 4: "At what price would [product] be so cheap that you would question its quality?" [open numeric field] ``` Add demographic/firmographic questions: role, company size (B2B), current spend on alternatives, urgency of need. **Path B — Gabor-Granger (sequential price presentation):** Present the product description, then show a randomly selected price point and ask: [src2] ``` "Would you purchase [product] at [$X]?" → Yes: show next higher price point → No: show next lower price point → Repeat until ceiling/floor reached or 5 iterations complete Record: highest price at which respondent said "Yes" ``` In Typeform: use Logic Jumps to route respondents to higher/lower price questions based on their Yes/No answer at each step. **Verify**: Test the survey yourself — complete it in under 5 minutes. Ensure all logic jumps work correctly and price questions accept only numeric input. **If failed**: If logic jumps break, simplify to showing all 5 prices and asking "Would you buy at this price? Yes/No" for each (monadic sequential design). ### Step 3: Distribute the Survey and Collect Responses **Duration**: 2-7 days **Tool**: Email, social media, paid panels, or customer outreach Target: minimum 100 completed responses per customer segment. ``` Distribution Channels (ranked by response quality): 1. Existing waitlist/email list — highest quality, already interested 2. LinkedIn outreach (B2B) — targeted by title/industry 3. Reddit/community posts — high engagement if relevant sub 4. Twitter/X posts — broad reach, lower completion 5. Paid panel (Prolific, Cint) — $1-3/response, fast, lower quality 6. Facebook/Instagram ads — $2-8/response via lead form ads Incentive guidance: - B2C: $5-10 Amazon gift card raffle (1 in 20 odds) - B2B: share the pricing research results with respondents - Paid panel: $1.50-3.00 per complete response ``` **Expected output**: CSV/spreadsheet with 100-500 responses, each row containing the 4 Van Westendorp prices or the Gabor-Granger maximum WTP, plus demographics. **Verify**: Response count >= 100 per segment. Check for straight-liners (identical answers across all questions) and remove them. **If failed**: If under 50 responses after 5 days, switch to a paid panel (Prolific) and budget $150-$300 for 100-200 responses. ### Step 4: Analyze Survey Results **Duration**: 1-2 hours **Tool**: Google Sheets or Excel **Path A — Van Westendorp Analysis:** ``` Van Westendorp Analysis Steps: 1. Sort all responses for each question (too cheap, bargain, expensive, too expensive) in ascending order 2. Calculate cumulative frequency for each price point: - "Too cheap" → cumulative % from low to high (ascending) - "Bargain" → cumulative % from low to high (ascending) - "Expensive" → cumulative % from HIGH to LOW (descending = "not expensive") - "Too expensive" → cumulative % from HIGH to LOW (descending = "not too expensive") 3. Plot all 4 curves on one chart (X = price, Y = cumulative %) 4. Find intersections: - OPP (Optimal Price Point) = "too cheap" crosses "too expensive" - IDP (Indifference Price Point) = "bargain" crosses "expensive" - PMC (Point of Marginal Cheapness) = "too cheap" crosses "not expensive" - PME (Point of Marginal Expensiveness) = "not too expensive" crosses "expensive" 5. Acceptable price range = PMC to PME ``` **Path B — Gabor-Granger Analysis:** ``` Gabor-Granger Analysis Steps: 1. For each price point tested, calculate: - Purchase probability = (respondents who said Yes) / (total shown that price) 2. Plot demand curve: X = price, Y = purchase probability 3. Calculate revenue curve: Revenue = Price x Purchase Probability 4. Revenue-maximizing price = peak of revenue curve 5. Price elasticity = % change in demand / % change in price (calculate between each adjacent pair of price points) ``` **Verify**: OPP/IDP (Van Westendorp) or revenue-maximizing price (Gabor-Granger) falls within the competitive range identified in Step 1. If the optimal price is 2x+ higher than competitors, either the sample is biased or the value proposition is genuinely differentiated. [src3] **If failed**: If curves do not intersect cleanly (Van Westendorp) or demand curve is flat (Gabor-Granger), the product description was likely too vague — respondents could not evaluate value. Rewrite product description and re-survey a smaller sample (30-50). ### Step 5: Build Fake Door Test (Path C) or LOI Outreach (Path D) **Duration**: 2-4 hours **Tool**: Carrd/Unbounce + Stripe (B2C) or Email + DocuSign (B2B) **Path C — Fake Door with Credit Card Capture (B2C):** [src4] ``` Landing Page Structure: 1. Headline: clear value proposition 2. 3-5 bullet points: key benefits/features 3. Social proof: testimonials, logos, or "Join X others" 4. Pricing: 1-3 tiers (use survey-validated price range) 5. CTA button: "Pre-order Now" or "Reserve Your Spot" 6. Stripe Checkout: collect real credit card payment 7. Confirmation page: "Thank you! You will be charged when we launch. Expected: [date]. Full refund if we don't ship by [date]." Stripe Payment Link setup: - Create product in Stripe Dashboard → Products → Add Product - Set price to validated price point from Step 4 - Create Payment Link → copy URL → embed in landing page CTA - Enable "Allow customers to adjust quantity" if testing volume ``` **Path D — LOI Collection (B2B):** [src5] ``` LOI Template (email or document): Subject: Letter of Intent — [Product Name] This letter confirms that [Company Name] intends to purchase: - Product: [name and description] - Quantity/Seats: [number] - Price: $[amount] per [unit/month/year] - Timeline: Purchase upon [GA launch / feature X completion / date] - Conditions: [any conditions — e.g., "SOC 2 compliance", "SSO support"] This letter is non-binding but represents genuine purchase intent. Signed: _______________ Name: _______________ Title: _______________ Company: _______________ Date: _______________ ``` Target: 3-5 LOIs (B2B) or 20-50 pre-order transactions (B2C) as minimum viable validation. **Verify**: Stripe dashboard shows successful charges (not just checkout starts). For LOIs, verify signer has purchasing authority (Director+ title). **If failed**: If conversion rate is below 1% on landing page after 500+ visitors, the price is likely too high or the value proposition is unclear. Reduce price by 20% and retest, or improve the landing page copy. ### Step 6: Synthesize Results and Produce Pricing Recommendation **Duration**: 2-3 hours **Tool**: Google Sheets + document editor ``` Pricing Recommendation Memo Structure: 1. EXECUTIVE SUMMARY - Recommended price: $X [range: $Y - $Z] - Confidence level: high/medium/low - Evidence strength: [N] survey responses + [M] paid transactions/LOIs 2. SURVEY FINDINGS - Method used: Van Westendorp / Gabor-Granger - Sample: [N] respondents, [segments] - Acceptable price range: $[PMC] - $[PME] - Optimal price point: $[OPP] or revenue-maximizing: $[RMP] 3. TRANSACTIONAL VALIDATION - Method: Fake door / pre-order / LOI - Results: [M] transactions at $[price], conversion rate [X%] - Total revenue collected: $[amount] - OR: [M] LOIs signed, total committed value: $[amount] 4. CALIBRATION - Survey-to-actual ratio: stated WTP was [X]% higher than actual payment behavior (typical: 3-5x overstatement) - Adjusted recommended price: $[final price] 5. RISKS AND CAVEATS - Sample bias: [description] - Market timing: [description] - Competitive response: [description] 6. NEXT STEPS - A/B test [2-3 prices] in-market - Review pricing quarterly using [method] ``` **Verify**: Final recommendation is supported by both survey data AND transactional evidence. If only survey data exists, explicitly flag that pricing is unvalidated. **If failed**: If survey and transactional results contradict each other (survey says $99, but nobody pays above $49), trust the transactional data — it reflects real behavior. ## Output Schema ```json { "output_type": "pricing_validation_report", "format": "JSON", "columns": [ {"name": "recommended_price", "type": "number", "description": "Final recommended price point in USD", "required": true}, {"name": "price_range_low", "type": "number", "description": "Lower bound of acceptable price range (PMC or minimum viable)", "required": true}, {"name": "price_range_high", "type": "number", "description": "Upper bound of acceptable price range (PME or maximum tested)", "required": true}, {"name": "survey_method", "type": "string", "description": "van_westendorp or gabor_granger", "required": true}, {"name": "survey_sample_size", "type": "number", "description": "Total completed survey responses", "required": true}, {"name": "transaction_count", "type": "number", "description": "Number of real payments or signed LOIs collected", "required": true}, {"name": "transaction_total_usd", "type": "number", "description": "Total USD collected via pre-orders or committed via LOIs", "required": true}, {"name": "conversion_rate", "type": "number", "description": "Fake door conversion rate (transactions / unique visitors)", "required": false}, {"name": "confidence_level", "type": "string", "description": "high (survey + transactions), medium (survey only), low (insufficient data)", "required": true}, {"name": "segments_tested", "type": "number", "description": "Number of distinct customer segments validated", "required": true} ], "expected_row_count": "1 (single recommendation per product/tier)", "sort_order": "N/A — single record", "deduplication_key": "product_id + segment" } ``` ## Quality Benchmarks | Quality Metric | Minimum Acceptable | Good | Excellent | |---------------|-------------------|------|-----------| | Survey sample size (per segment) | >= 50 | >= 100 | >= 300 | | Survey completion rate | > 40% | > 60% | > 80% | | Fake door conversion rate (B2C) | > 1% | > 3% | > 5% | | LOI count (B2B) | >= 2 | >= 5 | >= 10 | | Price range confidence interval | +/- 30% | +/- 15% | +/- 10% | | Survey-to-transaction calibration | Available | Calculated | Validated with A/B test | **If below minimum**: If survey responses are under 50, extend collection period or switch to a paid panel.

[src5] ## Error Handling | Error | Likely Cause | Recovery Action | |-------|-------------|----------------| | Van Westendorp curves don't intersect | Product description too vague — respondents guessed randomly | Rewrite product description with specific features and benefits; re-survey 30-50 respondents as pilot | | Gabor-Granger shows flat demand curve | Price range too narrow or product perceived as commodity | Widen price range by 2x in both directions; add differentiation messaging | | Fake door conversion rate is 0% | Price too high, wrong audience, or landing page fails to convey value | Test 50% lower price; verify traffic source matches ICP; A/B test headline | | Stripe payment failures (card declined) | Test cards used accidentally, or international cards blocked | Verify Stripe is in live mode (not test mode); enable international payments in Stripe dashboard | | Survey respondents all say "too expensive" at every price | Sample does not match ICP, or product solves a nice-to-have problem | Verify survey distribution targeted actual buyers; consider whether the problem is painful enough to warrant a paid solution | | LOI signers don't have purchasing authority | Outreach targeted individual contributors, not decision-makers | Re-target outreach to Director+ or VP-level contacts; verify title before sending LOI | | Survey results vary wildly across segments | Segments have fundamentally different willingness to pay | This is a feature, not a bug — build segment-specific pricing tiers | ## Cost Breakdown | Component | Free Tier | Paid Tier | At Scale | |-----------|-----------|-----------|----------| | Survey tool (Typeform/Tally) | 10-100 responses/mo free | $25-39/mo (500+ responses) | $83/mo (10K responses) | | Landing page (Carrd/Unbounce) | 1 site free (Carrd) | $19/yr Carrd Pro, $99/mo Unbounce | $99-200/mo (multiple variants) | | Payment processing (Stripe) | 2.9% + $0.30/txn | Same | Volume discounts at $80K+/mo | | Survey panel (Prolific/Cint) | N/A | $1.50-3/response | $1-2/response at 500+ | | E-signature (DocuSign/PandaDoc) | Free tier available | $10-25/mo | $25-65/mo | | **Total for 200 surveys + 50 transactions at $50** | **$0** | **$25-75** | **$150-300** | ## Anti-Patterns ### Wrong: Treating survey responses as validated pricing Founders who price based solely on Van Westendorp or Gabor-Granger results overprice by 30-50%. Survey respondents systematically overstate willingness to pay because there is no real cost to saying "yes, I'd pay that." Patrick Campbell of ProfitWell documented that stated willingness to pay runs 3-5x higher than actual purchase behavior across hundreds of SaaS companies. [src6] ### Correct: Always follow survey research with transactional validation Run the survey first to identify the acceptable range, then validate 2-3 price points within that range using real money (credit card charges, pre-orders, or LOIs). The survey narrows the search space; the transaction proves the price. ### Wrong: Running a fake door test without clear refund disclosure Collecting credit card payments for a product that doesn't exist yet without disclosing the pre-order nature and refund policy violates FTC guidelines and consumer protection laws. It also triggers Stripe chargebacks that can freeze your payment processing account. [src4] ### Correct: Transparent pre-order with explicit terms State clearly: "This is a pre-order. You will be charged $X today. If we do not launch by [date], you will receive a full refund." Include a refund link in the confirmation email. This builds trust and is legally defensible. ### Wrong: Surveying fewer than 50 respondents and calling it validated Small samples produce price ranges so wide they're useless. With 30 respondents, a Van Westendorp analysis might show an "acceptable range" of $10-$200 — which tells you nothing actionable. [src1] ### Correct: Minimum 100 respondents per segment If budget or reach constrains sample size, focus on one segment (your best-fit ICP) and get 100+ responses from that group rather than spreading 50 responses across 3 segments. ## When This Matters Use when an agent needs to produce real evidence that target customers will pay a specific price — not a pricing strategy document, but actual survey data and transaction receipts. This recipe is required before finalizing pricing tiers, launching pre-sales, or presenting pricing evidence to investors. The output feeds directly into pricing tier design and landing page construction. ## Related Units - [Value-Based Pricing for SaaS](/business/pricing/value-based-pricing-saas/2026) — pricing strategy framework that defines what to validate - [SaaS Pricing Models Comparison](/business/pricing/saas-pricing-models-comparison/2026) — final tier design using validated WTP data - [Product-Market Fit Framework](/business/gtm/product-market-fit/2026) — PMF context for pricing validation - [Freemium Decision Framework](/business/pricing/freemium-decision-framework/2026) — freemium vs paid decision using WTP thresholds - [Enterprise Pricing Strategy](/business/pricing/enterprise-pricing-strategy/2026) — alternative with full conjoint analysis for complex products
