Two research instruments, zero methodology decisions left to you.
Create a survey
curl -s -X POST http://localhost:8109/api/surveys \
-H "Content-Type: application/json" \
-d '{"email":"pm@co.dev","type":"vw","product_name":"Acme Analytics"}'
Type is vw (pricing)
or pmf (product-market fit).
Questions come pre-written per method.
Reading results
VW surveys produce the four curves, the acceptable range, the optimal price point, and the point of resistance, each translated into a plain-English finding on Pro. PMF surveys report the very-disappointed share against the forty percent benchmark with segment cross-tabs.
The two methods
- Van Westendorp (1976) derives pricing insight from four relative price questions rather than absolute willingness-to-pay guesses.
- Sean Ellis test (2009) correlates disappointment-at-removal with retention-derived product-market fit.
