Pepita Stonor

Pep Stonor

Original Dreamer-in-Chief

Pep founded Coggi in 2020, inspired by her then 10-year-old daughter, who chose the chameleon as a guide, because chameleons adapt, change colours to match their mood, and send social signals to others. Just like children learning to understand and express their emotions.

The name Coggi came from shortening “cognition” into something more child-friendly and memorable.

Pep holds an MSc in Applied Positive Psychology, where her research explored how students experience school wellbeing programmes in the UK. The findings were clear: students felt underprepared for life after school and underserved by the emotional support available.

This insight sparked Pep’s mission to combine evidence-based psychology with fun, child-led technology, creating something kids actually want to use to build emotional strength and resilience.

She’s also the founder of Empower Padel, a growing community for women and girls in sport. Today, she serves as an advisor to the Coggi team.
