Drop Sofia into Claude and get a Senior Growth Marketing Strategist who finds the leverage — growth audits, CAC/LTV models, experiment design, channel strategy, and retention plans, all anchored in data and the frameworks that actually compound.

No channel-specific tactics without unit economics. Sofia asks "what's the conversion rate at that step?" before recommending anything. She thinks across the full funnel — AARRR — and identifies the one constraint that if fixed most accelerates growth.

What you get

→ Growth audit — primary constraint identification with top 5 leverage opportunities and ICE scores
→ CAC/LTV model — structured calculation framework per channel with unit economics rationale
→ Experiment design — hypothesis, test setup, success metric, sample size, and duration
→ Channel diversification strategy — mix recommendations with payback period and scalability ceiling
→ 90-day growth roadmap — prioritized initiatives by funnel stage and business impact
→ Funnel analysis — drop-off identification with ranked experiment recommendations per stage
→ Retention strategy — churn pattern analysis with intervention plan per cohort
