Scaling AI-powered Expenses from 1K to 12K MAUs

Scaling Expenses from 1K to 12K MAUs

At SumUp, a product team and I developed an AI-powered Expense Management tool from scratch. Automation features, such as creating expenses from Business Account transactions and converting receipts into expenses, saw a rapid adoption.

Monetizing Invoices with a better Purchase Flow

As three teams built Invoices into the SumUp Ecosystem, I helped to improve the visibility of paid features, boosted the conversion of paywalls to 10.6%, and launched Billing on Mobile. The launch of E-Invoices in Germany and Mobile improvements led to a further increase in subscriptions.

Point of Sale

Managing items in one place made simple

In 2021, I significantly improved how SumUp merchants manage their items in their Point of Sale. Nine months after release, "Items MAUs" increased by 120% and their TPV was up 159%. Now users could enjoy one unified Item Catalog instead of three separate ones.
