Leadership Team

Mark Shashoua

Chief Executive Officer

Having co-founded the business (then called ITE Group) in 1991, Mark returned as CEO in 2017 with a strong vision for the company’s potential and initiated a Group-wide transformation to future-proof the business. That transformation saw the company radically evolve. It changed from siloed working to a centralised model of best practice, from an emerging markets focus to a portfolio 95% rooted in advanced economies, and from a sprawling portfolio of mixed quality products to a streamlined focus on only market-leading events. This led to the average revenue per event increasing more than eight-fold, and attention is now on expanding the company’s digital products. Thanks to Mark’s leadership, the Hyve of today has resilience, diversity and enormous scalability.
 
Transforming businesses is in Mark’s DNA and prior to re-joining Hyve, Mark was CEO of i2i Events Group, the event arm of Ascential plc, where he led the internationalisation and diversification of the business. It was at i2i that he first adopted a market leading event only approach that led to turning a declining business to one of consistently high organic growth. This was supplemented by a number of leading acquisitions including Money20/20, which grew substantially under his guidance. 
 
Mark is driven by his ambition to reimagine the events industry, disrupting it through digitisation. His aim is to transform everyone’s expectations of what’s really possible at events and help customers to realise the game changing possibilities that Hyve events hold for businesses and beyond.

Prior to that, John was Finance Director at Precise Media from 2008 to 2010.

John’s background in finance and operational transformation, as well as his experience in the events sector, underpins his passion for bringing about positive change and disruption within the industry. John enjoys working in a change-led environment and loves the passion, energy and sense of achievement that occur as the company, and the people working within it, realise their potential.
