How does the 1:1 mentoring work?

What kind of topics can we discuss?

Once you join, you’ll get access to me via Slack. You can message me directly with questions, share challenges, or ask for feedback, and I’ll reply with tailored advice for your situation.

Anything CRO-related: A/B test planning, hypothesis generation, prioritization frameworks, interpreting data, setting up tests, statistical approaches, or even building your career as a CRO professional or freelancer.

Is there a limit to how many questions I can ask?

Can beginners join, or is this only for experienced CROs?

Nope! You can ask as many questions as you want each month—whether it’s about test ideas, data interpretation, career growth, or freelancing.

Beginners are welcome! Whether you’re starting your first A/B test or looking to refine your skills, I’ll guide you based on your level and goals.
