Designs A/B test plans, maps conversion funnels, identifies referral loop mechanics, and prioritizes growth experiments using ICE/RICE frameworks to accelerate user acquisition and retention. Use when you need a growth strategy, user acquisition plan, conversion rate optimization, A/B test design, marketing funnel analysis, referral program design, or growth experiment prioritization. Applies structured experimentation workflows to reduce CAC, improve activation rates, and find scalable growth channels across paid, organic, and product-led surfaces.
