When Convert wins

  • Marketing and CRO teams running 5+ tests per month with budgets to match
  • Companies scaling out of free Optimize or VWO Free tier deprecations
  • Mid-market e-commerce running structured experimentation programs

Where Convert is the wrong fit

  • Small teams that can use PostHog feature flags and experiments for free
  • One-test-a-quarter buyers where cost-per-test is too high
  • Enterprises with Optimizely contracts where switching incentive is weak

When PostHog wins

  • Technical product teams that want one tool covering analytics, experiments, replay, and surveys
  • Startups under 1M events per month, where the free tier covers the entire stack
  • Companies committed to open-source infrastructure who want the option to self-host

Where PostHog is the wrong fit

  • Marketing-only teams who need attribution and campaign analytics (Mixpanel or GA4 fit better)
  • Enterprises with strict procurement that requires a SaaS-only vendor with no self-hosted option in scope
  • Non-technical users who cannot navigate event-based analytics UIs and SQL-style insights
