The problem
You're guessing what to grow and hoping it works
- You know you need to run experiments, but every article gives different advice. Nothing fits your specific situation.
- You ran something, got numbers, but have no idea if they're good or bad. The experiment ends with a shrug.
- Results live in spreadsheets and Notion docs. No structure, no learnings captured, no compounding knowledge.

Strong performance: Your open rate (45%) significantly beats the industry average of 21%. The 8% activation lift shows your content resonates with new users.
Watch out: The click-to-activation ratio suggests users are interested but hitting friction after clicking. Something in the activation flow may be blocking them.
Try next: Test different CTA placements in your emails, or simplify the first activation step. Consider a "Simplify signup form" experiment.

Learn the fundamentals of growth experimentation. Written for solo founders, not growth teams.
How to run your first growth experiment
Running your first growth experiment feels overwhelming, but it doesn't need to be. This guide walks you through the entire process from hypothesis to results, with practical examples you can copy.
ICE scoring explained: how to prioritize experiments
You have 20 experiment ideas and time for 3. ICE scoring helps you pick the right ones by rating each idea on Impact, Confidence, and Ease. Here's how to use it without overthinking.
What to do when an experiment fails
Most experiments fail. That's not a bug in the process; it's a feature. Failed experiments teach you more than successful ones, but only if you know how to extract the lessons and decide what comes next.
How many experiments should you run per month
Experiment velocity matters more than any single experiment. Founders who run 4-6 experiments per month learn 10x faster than those who run one per quarter. Here's how to find the right pace for your situation.
How Golden Gecko works
Common questions about growth experiments and how Golden Gecko helps.
What is a growth experiment?
A growth experiment is a structured test to improve a specific business metric. You form a hypothesis, change one thing, measure the result, and learn from it. Unlike random tweaks, experiments build compounding knowledge about what works for your product.
How do I prioritize which experiments to run?
Use the ICE framework: score each experiment on Impact (how much will it move the needle), Confidence (how sure are you it'll work), and Ease (how quickly can you run it). Golden Gecko's AI does this automatically based on your goals and past results.
What are growth playbooks?
Growth playbooks are proven experiment templates based on what worked for real companies like Slack, Dropbox, and Duolingo. Each playbook includes step-by-step instructions, expected results, and the metrics to track. You adapt them to your product instead of starting from scratch.
Who is Golden Gecko for?
Golden Gecko is built for solo founders, indie hackers, and solo growth leads who need to run experiments but don't have a growth team. If you know you should be testing but aren't sure what to test or how to interpret results, this is for you.
How much does Golden Gecko cost?
Golden Gecko is free to start with 3 active experiments and the full playbook library. Pro is €15/month (or €144/year) and unlocks AI experiment matching, results interpretation, and unlimited experiments. Every signup gets a 7-day Pro trial, no credit card required.
What's the difference between a growth experiment and an A/B test?
An A/B test is one type of growth experiment where you show two versions to different users simultaneously. Growth experiments are broader — they include before/after tests, feature launches, pricing changes, and more. Most solo founders don't need full A/B testing to learn fast.
How many experiments should I run per month?
For solo founders, aim for 2–4 experiments per month. Velocity matters more than perfection. One well-documented experiment per week builds serious compounding knowledge over a quarter. Golden Gecko helps you maintain this pace without burning out.
