Open the live funnel first. The redesign hangs on three things — intent, urgency, and being ready to pay.

The live version positions Bill Vampire as an emergency rescue kit: no bank login, see the result before signup, and a one-time $4.99 unlock the moment you need the scripts and proof files.

Paid Unlock
TL;DR
Bill Vampire started as a playful tracker. I rebuilt it into an emergency kit: high intent, no bank login, see results first, pay $4.99 only when the kit is worth it. Every step of the funnel is wired to a measurable signal.

1Commercial Design System

This isn't a visual refresh. It reframes the product around one urgent job, a low-friction preview, a clear one-time price, and analytics that show exactly where intent turns into payment.

AcquisitionProblem-first landing

Lead with the painful moment — surprise charge, trial renewal, or a service that's hard to cancel.

ActivationResults before account

Let users paste, upload, or speak before signup, so the product earns its keep early.

MonetizationOne-time rescue kit

Package the payment around urgency: cancel path, refund script, evidence list, reminder.

MeasurementEvent taxonomy

Instrument every decision point, from landing view to kit purchase to saved case file.

EventQuestion answeredDesign lever
landing_viewedDoes the emergency framing pull the right traffic?Hero, price pill, trust claims
emergency_selectedWhich pain mode carries the strongest intent?Scenario cards, copy hierarchy
preview_generatedCan users reach value before signup?Input flow, AI extraction confidence
checkout_clickedIs the $4.99 kit obviously worth it?Paywall timing, unlock language

2Background & Motivation

A user who just got charged doesn't want a dashboard. They want the next action.

The original tracker had personality but weak commercial intent. So I cut the value prop from broad spending awareness down to one rescue flow: detect the charge, pick the emergency, generate the kit, then unlock the assets worth paying for.

5Design Challenges

  • Move from entertainment to urgency without losing what made Bill Vampire stick in your head.
  • Earn trust without bank access — by showing clear inputs, honest evidence handling, and a concrete next step.
  • Make the $4.99 moment feel like a fair unlock, not a paywall that jumps you in the dark.

Measure & Iterate

The redesign started with the monetizable job — get a user out of a charge right now. From there I mapped events, rebuilt the landing hierarchy, packaged the Emergency Kit, and wired analytics so every design decision ties back to a conversion signal.

What I Learned
Commercial design is product strategy in interface form. The biggest win wasn't a prettier UI — it was stitching brand, price, trust, analytics, and the exact next action a stressed user needs into one system. Pretty is easy. Wiring it to a number is the job.
