Co-creating & validating One Web App

With banking, invoicing and accounting split across separate Shine products, I led two co-creation sprints in Copenhagen and Paris to design a Unified Web App in two weeks. Maze tests across four markets showed increased satisfaction from 3.7 to 4.2 and cut time on task to up to 65%.

Expenses

Scaling AI-powered Expenses from 1K to 10K 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.

Invoices

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.

Design Leadership in Practice

At Shine, I hired six designers in six months through active sourcing and a referral strategy. I build trust and clarity so designers feel seen and supported. I turn product strategy into vision videos and prototypes that other Heads of Design adopted.
