Sample events
trial_started, payment_submitted, plan_upgraded Examples +
A SaaS tool has 3.5% free-to-paid conversion. Users who use the collaboration feature convert at 11%. The team makes collaboration more prominent in the free tier.
Suggested decisions +
- Below 2%: the free experience may not demonstrate enough paid value
- Between 2-5%: typical for freemium. Investigate what converts power users.
- Above 10%: strong conversion. Check if the free tier is too restrictive.
