I just documented the 20 best growth experiments of the past 10 years.
They require almost no traffic, budget, or tech.
You can even run them in a corporate! (And you probably won't get fired 😏)
They cover the critical stages:
- Signal mining & problem discovery 
- Market sizing 
- Demand validation 
- Messaging and positioning tests 
- Feature validation 
- Feasibility 
- Channel tests 
- Willingness to pay & price sensitivity 
You'll get instructions and examples for:
- Fake door test 
- Wizard of Oz test 
- Van Westendorp Price Sensitivity test 
- Review mining 
- Discussion forum audits 
- Validation interviews (AKA "Mom-Test interviews") 
- In-Situ demand test (AKA "The Empty Box Test") 
- Five Second Test (AKA "Paper Test") 
- And more... 
I pulled them into a PDF with step by step instructions, real-world examples and screenshots.
Want a copy?
I hope it helps!
