/Case C / Momentum in Motion

Month two nearly doubled month one. Across every metric.

Accounts, response rate, balances. Pick any headline number from this program’s first month, and the second month roughly doubled it. Two months in, the strongest month is still the most recent one. That is what early momentum looks like when the targeting is right.

What Happened

Accounts grew from 42 to 83. Response nearly doubled, from 0.45% to 0.89%. Balances more than doubled, from $624,558 to $1,258,551. Two months, 125 accounts, $1.88 million.

Why It Worked

The clearest signal is in term deposits. CD balances went from zero in month one to $350,752 in month two. Members do not park CDs at an institution they are testing. They park them where they are staying.

What It Means for You

234% ROMI at month two is early innings value. Case A shows what the same curve looks like at month four. The trajectory, not the snapshot, is the number to price.

Momentum like this is a targeting outcome, not a lucky month.
