Learning goal
You will be able to: Design a small growth experiment with a clear success metric.
Success criteria (observable)
- One experiment is defined with a clear hypothesis.
- A metric and target are written.
- A start and end date are set.
Output you will produce
- Deliverable: Growth Experiment Plan
- Format: One page plan
- Where saved: Course folder under
/generative-ai-2026-build-ai-apps-and-agents/
Who
Primary persona: Digital nomad testing growth channels Secondary persona(s): Users who might try the product Stakeholders (optional): Collaborators
What
What it is
A small, time boxed experiment to test one growth idea. It focuses on learning, not scale.
What it is not
It is not a long term marketing strategy or a big campaign. It is a quick test to find early signals.
2-minute theory
- Small experiments reduce wasted marketing spend.
- Clear metrics make learning objective.
- One experiment at a time keeps focus.
Key terms
- Hypothesis: A testable statement about expected results.
- Metric: The number you track to judge success.
Where
Applies in
- Growth planning
- Marketing tests
Does not apply in
- Core product development
Touchpoints
- Landing page
- Email signup
- Ads or outreach
When
Use it when
- You want early traction signals
- You have a working product to share
Frequency
One experiment per week or per month
Late signals
- Many ideas but no tests
- No measurable growth data
Why it matters
Practical benefits
- Faster learning
- Lower marketing risk
- Clearer channel decisions
Risks of ignoring
- Random marketing efforts
- Slow growth learning
Expectations
- Improves: learning speed
- Does not guarantee: growth
How
Step-by-step method
- Choose one channel to test.
- Write a clear hypothesis.
- Define a metric and target.
- Set start and end dates.
Do and don't
Do
- Keep the test small and time boxed
- Track one primary metric
Don't
- Run multiple tests at once
- Skip the hypothesis
Common mistakes and fixes
- Mistake: No metric. Fix: Choose one number to track.
- Mistake: No time box. Fix: Set start and end dates.
Done when
- Hypothesis is written.
- Metric and target are defined.
- Dates are set.
Guided exercise (10 to 15 min)
Inputs
- Product value proposition
- One growth channel idea
Steps
- Write a hypothesis.
- Define the metric and target.
- Set dates and a budget.
Output format
| Field | Value |
|---|---|
| Channel | |
| Hypothesis | |
| Metric and target | |
| Dates and budget |
Pro tip: Choose a channel you can execute in one day.
Independent exercise (5 to 10 min)
Task
Cut the experiment scope by 50 percent and keep the metric.
Output
Revised experiment plan.
Self-check (yes/no)
- Is the hypothesis testable?
- Is the metric clear?
- Is the time box defined?
- Is the scope small?
Baseline metric (recommended)
- Score: 1 experiment defined
- Date: 2026-02-06
