I build global SaaS customer success functions that grow retention, adoption, and expansion revenue.

At Mercaux, I joined as the first Customer Success hire and built the global CS function across EMEA, North America, and APAC. I created the playbooks, onboarding frameworks, Gainsight health scoring, and QBR cadences needed to scale.

I delivered 98% NRR, 15% year-over-year expansion revenue growth, and lifted product adoption from 46% to 78% through lifecycle interventions and in-app engagement campaigns. I also grew the team from 2 to more than 7 CSMs while establishing OKRs, performance reviews, and coaching practices.

Previously at Nosto, I established the UK and Ireland CS function and managed 80+ enterprise eCommerce customers. I maintained churn below 10%, drove 32% adoption growth, and contributed to a 12% increase in regional expansion ARR.

I bring experience connecting customer outcomes with product, sales, and operational execution across global technology organisations including Microsoft. I use AI tools such as ChatGPT and Claude to improve customer analytics, QBR storytelling, communications, and CS processes.
