Bringing AI in at SumUp

Decide how AI should propose audiences once 5 of 12 briefs overlap

Published Oct 30, 2026

You’re a forward deployed engineer working with SumUp’s marketing team. The team is in the room.

The setting

extends its payments work to individual people with , a mobile wallet app with a virtual Mastercard for paying friends, settling bills and paying businesses.

A funded account does not identify which first-payment prompt belongs next.

Growth wants distinct audiences to test, while CRM protects consumers from competing contact across running campaigns.

Who you’d be doing this for

“I put money in after shopping, then got two different prompts. Which one am I supposed to follow?”

Alvar Eriksson · Personal account customer · a character in this brief

Joined through a merchant, funded the account and has not yet made a first payment.

What is at stake

Growth strategists found overlapping audiences in five of 12 briefs for first-payment campaigns. You decide whether AI proposes membership directly or proposes criteria for a strategist to approve before the system builds the audience.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • distinct audience hypotheses vs comparable experiments
  • cross-channel reinforcement vs competing contact
  • fine-grained targeting vs usable audience size
  • fresh membership vs reproducible approvals
