The household problem

The acquisition funnel said the feature worked. Onboarding flow conversion was strong, time-to-first-investment was healthy, primary-account engagement looked normal. Multi-account engagement, though, was stuck at ~10% — a number we’d been quietly reading as “people just don’t want multiple accounts.”

Behavioral data told a different story. The customers we thought were single-account users were checking spouse, parent, child accounts on each session — they just couldn’t do it through the app, so they were toggling between phones, calling RMs, or asking the customer to forward their statement.

We stopped designing for the user and started designing for the household. The unit of value in wealth isn’t the individual login — it’s the financial decisions a household makes together.

The work split into two layers: a permission model that let one user view-and-act across linked accounts with explicit consent trails, and a UI layer that made the household the default view rather than a hidden toggle.

The funnel didn’t need to be optimized. It needed to be repositioned to measure the right thing.

Multi-account engagement climbed from ~10% to ~30% within two quarters of the household view shipping. Retention on multi-account households outperformed single-account ones by a meaningful margin — and the qualitative shift was that customers started talking about Dezerv as “our” platform, not “my” platform.
