Financial Ecosystem for Kids
Teach Money, Play Smart — a gamified banking ecosystem that gives children safe autonomy and parents real oversight.
Preview — child app walkthrough
Eight percent of an eligible base
Roughly 1.3M of them were parents — the eligible base for junior banking. Only 100,000 kids were enrolled: under 8% of that base actually converted.
Digging into the funnel, three drop-off points stood out:
Two audiences, opposite asks
I started by interviewing existing Center Credit clients with children — parents control the money, so their buy-in had to come first. I also interviewed the kids directly, since they're the ones who'd actually use the app daily.
Parents wanted
Trust & control
Kids wanted
Freedom & ownership
Parents wanted a way to teach their kids the value of money without losing oversight. Kids wanted the opposite framing — real autonomy, their own money, their own account, not a monitored allowance.
That tension was the core design problem: build something that reads as "freedom" to a ten-year-old and "control" to their parent, without the two experiences fighting each other.
Where I hit resistance
The registration fix — auto-filling child data from a government database sync so parents only entered a phone number — was the single highest-leverage idea from research. It also nearly didn't ship as designed.
The dev team flagged the real-time sync as too complex, requiring a rearrangement of the existing architecture, and pushed for a batch overnight sync instead. From their side this was a fair call — gov databases were heavy to query, and a failed sync mid-registration would leave accounts in a broken state. To make the case for keeping it real-time, I put together a presentation for the dev lead showing the drop-off math, then we sat down together through the API docs to find a narrower version that justified the engineering cost. We landed on syncing a limited subset of fields, with the rest left editable later.
There was also internal disagreement on priority. Business wanted to lead with the cashback mechanic to drive short-term registrations; based on the parent interviews, I argued that leading with trust and safety framing would convert better and retain longer. We ran an A/B test: one version kept the old, longer registration flow but led with the appealing cashback terms; the other used the new simplified registration with no cashback messaging at all.
The simplified-registration version won clearly — with the old flow, most users dropped off before ever reaching the cashback offer, so the "appealing" terms never even got seen. That settled the debate: cashback got moved later in the funnel, positioned as a retention lever rather than an acquisition hook.
Six features, one system
- Government database sync for registration — cut setup to a single phone number field. Parents wanted this to be effortless, not impressive; every extra field was a chance to abandon the process.
- Financial literacy lessons with rewards — gave kids a reason to open the app that wasn't tied to spending, translating parents' "teach them the value of money" ask into something a kid would actually choose to do.
- Parent-assigned tasks that pay real money — digitized the "chores for allowance" dynamic parents already used informally, so the app became the mediator instead of cash handed over at home.
- Saving accounts parents can contribute to — gave parents an active, ongoing reason to open the app beyond checking a balance, and gave kids a visible, growing number to care about.
- Cashback up to 10% on parent-chosen categories — repositioned after the A/B test as a loyalty mechanic, competing with rival cards on ongoing value instead of upfront offers.
- Near-frictionless transition to an adult account at 16 — a couple of taps to confirm continued membership, converting years of loyalty rather than losing users at the exact moment they become the most valuable.

Friction, not incentive, was the blocker
Figures below are approximate — some adjusted for confidentiality.
New junior account signups roughly tripled month-over-month following the simplified registration launch. Engagement improved from a very passive baseline — parents logging in a handful of times a month — to daily use driven mainly by kids opening the app for lessons, tasks, and saving goals.
In the cashback-vs-trust A/B test, the simplified-registration variant had an estimated ~2.5x higher completion rate than the cashback-led variant with the old flow — the clearest evidence that friction, not incentive, was the real blocker.
~70–75% of eligible users chose to continue as adult clients at the 16+ transition, rather than leave
That retention rate suggests the multi-year relationship built genuine loyalty — not just parental convenience.
