Gent Ahmetaj

Head of Insights

John is our CEO, working closely with our Board and all the members of our team to support us in fulfilling our mission. He has worked in many leadership roles across the world and enjoys supporting other leaders to achieve their best. John did his MBA at Northumbria University, and spends most of his spare time running (slowly), reading, writing, and collecting antique Chinese Government bonds. Yes, really.

John’s motto is “We are what we share”.

With over 20 years of experience in sales and marketing within the hotel, hospitality and events industries, Rebecca has a keen eye for creating impactful experiences that drive revenue growth and customer satisfaction.

Gent is our Head of Insights and a mixed-methods specialist dedicated to making complex information accessible and actionable. With 15 years of experience spanning advanced analytics, behavioural science, and multi-disciplinary research, he has led teams in corporate, not-for-profit, and academic settings across multiple regions. He holds a PhD in Organisational Behaviour and Design from Warwick Business School and has a keen interest in how and why organisational learning and leadership behaviour are distinctive features of successful businesses.
