# Whiskrr Validation Kit: Pricing Validation Experiment
**Block:** REVENUE STREAMS | **Priority:** HIGH | **Hypotheses Covered:** H1, H2
---
### Objective
Test pricing before committing to a model. Most early-stage founders price too low. This experiment finds the price point where conversion is still strong but you are not leaving money on the table.
---
### Where to Run the Experiment
**Survey-based WTP research (public communities):**
- Post a 4-question Van Westendorp survey in:
- r/SingaporeStartups (18K members) — https://reddit.com/r/SingaporeStartups
- r/startups (4.2M members) — https://reddit.com/r/startups
- Startup SG Slack (#product channel) — https://startupsg.net
- LinkedIn (your feed + 2 relevant Singapore groups)
**Pricing page A/B test (paid tools — free tiers available):**
- Carrd — https://carrd.co — SGD 9/month; build two pricing page variants
- Webflow — https://webflow.com — Free tier for 2 pages; more design control
- Unbounce — https://unbounce.com — Built-in A/B testing; SGD 90/month (14-day free trial)
**WTP benchmarking (public data):**
- Paddle State of SaaS Report — https://paddle.com/resources — Annual SaaS pricing benchmark; free download
- OpenView Pricing Survey — https://openviewpartners.com/blog/tag/pricing — Free reports on PLG pricing strategies
- Price Intelligently Blog — https://priceintelligently.com/blog — Free resources on B2B SaaS pricing methodology
**Singapore-specific price benchmarks (public):**
- MAS Digital Financial Services Data — https://mas.gov.sg/data — Singapore fintech and SaaS adoption data
- Gartner Peer Insights — https://gartner.com/peer-insights — Public user reviews with price satisfaction data
---
### The Van Westendorp Method
Ask these 4 questions (survey or interview):
1. At what price would you consider this **too expensive** to consider?
2. At what price would it be **expensive but still worth considering**?
3. At what price would you consider it **good value**?
4. At what price would it be **too cheap to be credible**?
Plot responses. Your launch price should be in the upper third of the acceptable range (between "too cheap" and "too expensive" intersections).
---
### Success Criteria
✓ Van Westendorp data from 30+ qualified respondents
✓ Acceptable price range clearly defined
✓ Pricing page A/B test run with 100+ visitors per variant
✓ Final price decision made before first paid customer
**Time:** 3 weeks — 1 week survey design + pricing page build, 2 weeks data collection
*AI-generated guidance. Communities, pricing and benchmarks may change. Only public communities are surfaced. Verify all links before using.*

# Whiskrr Validation Kit: Letter of Intent Collection
**Block:** REVENUE STREAMS | **Priority:** HIGH | **Hypotheses Covered:** H3, H4
---
### Objective
A signed LOI is the strongest pre-product validation signal available. It proves a real decision-maker with real budget intends to pay your real price. 5–10 signed LOIs is sufficient for a pre-seed raise conversation.
---
### Where to Find LOI Candidates
**Your existing pipeline first (highest conversion):**
- Re-contact every problem interview participant who said "when can I use it?" or rated the problem 8+/10
- Re-contact every solution interview participant who asked about pricing or early access
**Reddit (public — post "early access" announcements):**
- r/SingaporeStartups (18K members) — https://reddit.com/r/SingaporeStartups — "Looking for design partners / early customers"
- r/startups (4.2M members) — https://reddit.com/r/startups — Use "progress" or "milestone" flair
**LinkedIn:**
- Post an "early access" announcement with a clear CTA — "DM me if you want to be one of our first 10 customers"
- Direct message 30 highly qualified prospects from your screened list (people who passed problem + solution interviews but haven't been asked for LOI yet)
- Startup Founders & Entrepreneurs Singapore (28K members) — LinkedIn Group
**Startup ecosystem programs (in-person — warm intro context):**
- Antler SG — https://antler.co/singapore — Portfolio network; warm intros via cohort members
- SGInnovate Residency — https://sginnovate.com — Singapore deep-tech community; monthly networking events
- NUS Enterprise Startup Programmes — https://enterprise.nus.edu.sg — University-linked founder community
- DBS Startup Xchange — https://dbsbusinessclass.com/startupxchange — SG bank-supported accelerator community
**LOI template tools (free):**
- DocuSign Free Trial — https://docusign.com — Free for first 3 documents per month
- HelloSign (now Dropbox Sign) — https://sign.dropbox.com — Free tier: 3 signature requests per month
- Adobe Acrobat Online — https://acrobat.adobe.com — Free PDF signing for basic use
---
### LOI Document Structure
Keep it to 1 page:
1. Signatory: Name, title, company
2. Intent: "We intend to purchase [product] when commercially available"
3. Price: "At the price of SGD [X] per [unit/month]"
4. Use case: "For [specific use case]"
5. Non-binding clause: "This letter is non-binding and subject to final product review"
---
### The Conversation Sequence
Never ask for an LOI in the first conversation. The sequence is:
1. Problem interview → build trust, confirm pain
2. Solution presentation → show prototype or demo
3. Wait 24–48 hours → let them sit with it
4. Follow-up: "Would you be willing to sign an LOI? It's non-binding but helps us prioritise features for customers like you."
5. Send document within 1 hour of verbal yes
---
### Success Criteria
✓ 5+ signed LOIs from qualified decision-makers at different companies
✓ Total committed revenue in LOIs exceeds 3 months of operating cost
✓ At least 3 signatories have confirmed budget authority (not just "I would use this")
**Time:** 4–6 weeks — 2 weeks prospecting and outreach, 2–4 weeks in LOI conversations
*AI-generated guidance. Communities, pricing and benchmarks may change. Only public communities are surfaced. Verify all links before using.*

# Whiskrr Validation Kit: Customer Interview
**Block:** PROBLEM | **Priority:** HIGH | **Hypotheses Covered:** H1, H2, H3
---
### Objective
This interview campaign tests whether your target customers genuinely experience the problem at the stated frequency and severity. Research flagged three gaps: (1) no direct evidence customers find this painful enough to pay to fix, (2) the frequency claim is unverified, and (3) no data on current workaround costs. These interviews address all three simultaneously.
---
### Hypotheses This Kit Addresses
- **H1** — Validates whether the core problem occurs at the stated frequency and severity
- **H2** — Confirms the root cause and who owns the pain in the organisation
- **H3** — Explores how customers currently work around the problem and what they spend
