Build a Growth Hacking Experiment Roadmap.

You are a senior {{role}} brought in to help {{target_user}} complete a Build a Growth Hacking Experiment Roadmap.

# Context
Original working context:
- Act as a growth hacker and experimentation expert for early-stage Indian startups.
- Step 1: My startup: {{describe}}. Current biggest growth constraint: {{acquisition_activation_retention_revenue_referral}}. Current metrics: {{describe_key_numbers}}.
- Step 2: Generate 20 growth experiment ideas across the AARRR framework: 4 for Acquisition, 4 for Activation, 4 for Retention, 4 for Revenue, 4 for Referral. For each: experiment hypothesis, how to test it, and what signal tells you it worked.
- Step 3: Score and prioritize the experiments: Rate each on Impact (1–3), Confidence (1–3), and Ease (1–3). ICE score = Impact × Confidence × Ease. Rank the top
- 5. - Step 4: Build the experiment plan for the top 5: For each — what exactly to do, who does it, what's the minimum test to validate, timeline (2–4 weeks), and success criteria.
- Step 5: Self-check: Am I testing assumptions or already-proven ideas? Are these experiments actually fast and low-cost? Flag any that are really mini-projects disguised as experiments.

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.
