What this question tests

Tests founder-level strategic metrics thinking for an early-stage fintech, prioritizing the handful of numbers that actually predict survival.

Clarify the stage: early days means proving product-market fit and unit economics before chasing scale, so vanity metrics like total signups matter less.
Track activation: percent of approved cardholders who make a first purchase within 30 days, proving the card is actually being used, not just issued.
Track engagement depth: monthly transacting rate and average spend per active card, since a card sitting unused generates no interchange revenue.
Track unit economics closely: cost per acquisition against expected lifetime interchange and fee revenue, and early default or delinquency rate as a critical risk signal.
Define an early north star as monthly active transacting cardholders, since it combines both real usage and revenue-generating behavior in one number.

Prioritizes activation and transacting rate over signups, correctly identifying usage as the metric that predicts real business viability.
Names delinquency rate explicitly, a critical and specific risk metric for a credit product that a generic growth answer would miss.
Picks a combined north star, monthly active transacting cardholders, that captures both engagement and revenue potential together.

Tracking only card signups or approvals without any usage or activation metric.
Ignoring delinquency and default risk, a metric uniquely critical to a credit product's survival.

How would you balance approving more cardholders against managing credit risk at this early stage?
What would make you pause growth to fix unit economics first?
