# Peter Olusesan

> Software designer. I make things for the internet. Previously led design at Pleo for payments infrastructure, credit, and the shift from sales-led to product-led growth.

This is my personal studio site: case studies, essays, projects, and the
occasional photo album.

## Work

- [Pleo — Payments, credit and product-led growth](https://www.sesan.studio/work/pleo): Two-chapter case study. Chapter 1: designing Pleo's wallet, funding rails (Open Banking, Direct Debit, VRPs) and credit — insufficient-funds declines fell from 9.4% to 6.3%. Chapter 2: leading the design direction for Pleo's shift from sales-led to product-led onboarding across 16 markets.
