Personalized insurance

While Disney+ was in development, I kept looking at the future of insurance. Our research said our customers' pains weren't the ones our insurance covered. So I let them build their own insurance, and watched what they picked.

Context

At will bank I led design for commissioned products: insurance, mobile top-up and capitalization. Card insurance with Disney+ had just proved that our customers responded to the right offer. But it was still an old product with a new hook.

The goal was not just to launch a product, but to build a data ecosystem for future insurance offers. To get there, I organized the team's discovery in levels.

  1. StrategicLong term. Deep knowledge of customers' motivations, to decide which products to create. JTBD interviews, interviews about anxieties and the unexpected.
  2. TacticalMedium term. Fake doors to test concepts before building anything: coverages, new offer points, account insurance with Disney+.
  3. OperationalShort term. Data analysis and pricing research to optimize what was already selling.
Discovery in levels: a way to prioritize research so it serves both the long-term vision and the immediate revenue needs.

What the research said

We ran in-depth interviews with simple account customers, a strategic focus for the bank, to map the pains of people with no insurance. For customers who already had insurance, I built a JTBD bot with n8n and Figma Make that asked why they kept it. A second round of interviews went after their anxieties and the unexpected.

  • The pain that breaks the budget isn't death. It's health (medicine, exams, treatments) and losing income when you can't work.
  • People "hire" insurance for financial stability first, and to take care of their family second.
  • The biggest fear is paying for years and not being covered when it matters, or getting lost in red tape.
  • Insurance felt expensive and unnecessary. A fair price was somewhere between R$5 and R$100 a month.
  • The real competitor was inertia: trusting that nothing bad will happen, until it does.
  • For self-employed customers, the phone is a work tool. Losing it means losing income.

What weighs most

The closer to the center, the more it weighs. Family came first: 65% of the customers we heard were heads of household and 61% lived with children.

All of it adds up to one idea the team used as a compass: insurance as a tool to live well, not an end in itself.

If our insurance didn't cover what people feared, what would they pick themselves?

What I did

I used the same no-code fake door logic from the Disney+ test. A minicard on the Home screen led to a Figma Make prototype where people built their own insurance, choosing coverages one by one. Clarity recorded the sessions and Supabase stored every pick, price and drop-off.

I grouped eleven coverages by what they protect, and wrote the copy in our customers' own language: for your hustle (broken or stolen phone, motorcycle, work tools), for your family (family protection, funeral support, pharmacy allowance, health discounts, telemedicine) and for your pocket (daily pay on sick leave, scam protection).

25,195 people opened the prototype from Home, and 6,893 went through the whole journey. The URL told me which of four groups each one came from: simple or full account, and whether they had clicked an insurance offer before.

Prototype screen with a yellow header, 'protect yourself from the unexpected', and three groups of coverages: for your hustle, for your family, for your pocket.

Protect yourself from the unexpected

"Select the protections that make sense for your life and create a personalized insurance that fits your pocket."

Each group opened into its coverages, each with its own monthly price, from R$3.81 for funeral support to R$49.90 for the motorcycle.

What people picked

Behavior confirmed the interviews. People went straight for income and scams, well ahead of the phone or the motorcycle.

The bundles people built

117 people combined daily pay on sick leave with scam protection. 42 built a family set, and 35 a work set with phone, motorcycle and tools.

Family, again

Pharmacy allowance and health discounts let people add dependents. 156 did, mostly spouses (162) and children (49). Insurance stops being an invisible expense when the whole family can use it.

The perk people wanted most

Times each perk was picked, more than one allowed

  • A monthly R$10,000 prize draw

Who signed up

Simple account customers who had already clicked an insurance offer were the clear early adopters: 14.6% signed up, and they built more expensive insurance, R$35.56 a month on average. Full account customers dropped off more than 98% of the time and built cheaper insurance, around R$26.

What I proposed next

  • Sell to the early adopters now. A CRM campaign for simple account customers in recovery, offering the products we already had that were closest to financial security, talking about loss of income and scams.
  • Fake doors for each new insurance. Loss of income, scams, life with a health focus, work tools, motorcycle, broken phone. A "coming soon" screen after "Buy" to measure real intent and build a waitlist.
  • Build your own vs. ready-made bundles. An A/B test against three fixed bundles (Essential, Family, Professional) made from the top picks. Do our customers want to choose, or want it simple?
  • Talk to the people who left. 5 to 8 quick interviews with full account customers who entered the flow and picked nothing. Numbers alone couldn't explain 98% drop-off.

The research said health and income. The test showed the same thing with behavior, and gave us the prices, bundles and audience for the next insurance.

The plan was ready when the Central Bank of Brazil liquidated the bank. The fake door and the research bot became the benchmark for other teams at the bank.
