Growth experiments

One-liner: Run small experiments to find early traction.
Time: 20 to 30 min
Deliverable: Growth Experiment Plan

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

1. Choose one channel to test.
2. Write a clear hypothesis.
3. Define a metric and target.
4. 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

1. Write a hypothesis.
2. Define the metric and target.
3. 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
• Tool used: Notes app
