Most growth problems aren't growth problems — they're activation or retention problems wearing a growth costume. Before spending another dollar on ads, run the AARRR diagnostic.
Start with retention. If week-4 retention is below 20% for a SaaS product, no amount of top-of-funnel will save you. You have a leaky bucket. Fix the leak first.
Next look at activation. Define your 'aha moment' — the action that, once taken, predicts long-term retention. Measure what % of signups reach it within 7 days. If it's under 40%, your onboarding is the bottleneck.
Only after retention and activation are healthy should you scale acquisition. ProductBlaze automates this diagnostic and tells you exactly which stage to focus on this week.
