Hornby, who first joined the agency in 2009, has worked on its ‘growth mission’, which included Smyle acquiring Pumphouse Productions earlier this year and helping the business triple in size. It is forecasting a record £11m turnover in 2015 after winning significant new clients in the IT, telco, financial and media sectors.
Hornby is founder and CEO of strategic consultancy Why Not UK, and will move on to new opportunities in the events and live communications industry.
Rick Stainton, Smyle Group’s managing director, said: "David has played a significant role in helping the board through our growth mission, the recessionary impact and a focus on growing up internally.
"The company now has different requirements of support for its next development phase and David also has multiple other new projects he needs to focus on. So we all wish him well and he leaves as a long-term friend of Smyle and also remains a shareholder."
Hornby added: "It has been a real privilege to work with such an amazing team over the last five years. We developed a strong and clear vision for Smyle. Our team, partners and customers have helped us achieve this great success together. I would like to take this opportunity to thank Rick, Matt, Dominic & Andrew along with all of the Smyle family for their enthusiasm and support during both the tough and great times we have shared together.
"But as with all things, there comes a time to move on. The events and live communications industry is changing rapidly and I look forward to the next opportunity and wish Smyle continued great success in the years to come."
