Overview

The short version.

FunnelFab is a complete funnel platform with a twist: an AI assistant can drive it. An agency strategist opens Claude, describes the funnel a client needs, and the assistant imports the client's brand from their website, builds a multi-page funnel, checks it, and publishes it to the client's domain. The strategist can then fine-tune anything in the visual editor.

It's built for agencies that run many clients at once, so every client gets their own workspace with its own leads, domains, email sender and analytics.

The challenge

What was broken.

Agencies rebuild the same lead-generation funnel for every client: a quiz, a booking step, a thank-you page, then follow-up emails, all restyled to the client's brand. Each one took two to three hours in a drag-and-drop builder, and working out which step was losing people meant stitching together three analytics tools.

  • Hours of repetitive building and restyling per client funnel.
  • Drop-off analysis spread across several tools.
  • Follow-up emails sent from a generic address instead of the client's own.

The solution

What we built.

FunnelFab gives the AI assistant the whole product to work with: it can read the funnel playbook, import a brand, draft a funnel, validate it, edit individual blocks, publish, and later read back conversion numbers, heatmaps and leads. Everything the assistant builds is normal, editable funnel content, so the agency keeps full control. Email follow-ups send from the client's own Gmail or Outlook, and payments go straight to the client's Stripe account.
