Behavioral Nudge Engine

Users drop off at predictable moments — onboarding, first real value, renewal — and generic engagement tricks copied from other products often feel manipulative or simply stop working once the novelty fades. This service applies established behavioral-science principles, like well-timed defaults, social proof, and loss aversion, to design specific interventions at the exact moments they'll change behavior, then tests each one against a control group before it ships. It's for teams that want engagement gains that hold up under an ethics review, not just a short-term metrics bump. Every nudge we design has to earn its place with measured lift and a clear rationale a user wouldn't object to hearing.

How We’d Approach This

A clear, staged plan — not a black box

  1. 1

    Map the user journey to identify the specific drop-off points and friction moments worth targeting.

  2. 2

    Design two or three candidate nudges and A/B test each against a control group to measure real lift.

  3. 3

    Review results against both engagement lift and an ethical-use checklist before anything scales.

  4. 4

    Implement the validated nudges in product with tracking in place to monitor effect over time.
