Let an AI agent set it up

What FunnelFizz does​

You drag four stages onto a canvas (Awareness, Consideration, Trial, Customer) and FunnelFizz tells you in real time how many people made it through each one. It plugs into your tracking script, your Stripe account, and your social profiles so you stop guessing which posts drove signups and which trial users became paying customers.

It's one tool that replaces five:

  • End-to-end tracking. Stitch the same person from their first impression on X or YouTube, through your marketing site, into a Stripe trial, and out the other side as a paying customer (or a churned one). One profile, one timeline, every device.
  • Native email platform. Drag-and-drop MJML editor, dynamic recipient lists targeted by funnel stage, A/B testing, custom sender domain, full open and click tracking. No Mailchimp, no HubSpot.
  • Automation platform. DAGs of Send, Wait, and Split steps that fire on stage entry or Stripe events. Trial onboarding, churn recovery, A/B onboarding tests, all without touching code.
  • Splits and filters. Slice your funnel by traffic source, UTM, device, country, custom event, A/B variant, or Stripe product. See exactly what's working, who you're reaching, and what to double down on.
  • Full lifecycle, including upsell. Extension stages after CUSTOMER track which entry-tier customers upgrade to higher tiers. Retained, upgraded, churned, all separated.

It's built for the kind of person who shouldn't be spending three weekends wiring up HubSpot:

  • Solo founders who want one tool instead of nine.
  • Vibe coders who'd rather let their AI agent do the setup.
  • Small SaaS teams that need a shared view of the funnel without enterprise pricing.
