Smarkets has announced a strengthened executive team.

Robin Harrison, a former engineering team lead at the company, has re-joined the company as Chief Technology Officer after a year in the role of Head of Engineering at Asto, a fintech startup backed by global bank Santander.

Meanwhile, Tom Hardman and Céline Crawford have been promoted to Chief Operations Officer and Chief Communications Officer respectively.

Hardman, who formerly held the title of Head of Business Operations, is one of Smarkets’s longest-serving employees having joined in 2010 after graduating from Oxford University. During his time at the company, he has overseen many areas including finance, legal and customer support.

Crawford has been with Smarkets since 2015 after working in the banking and communication sectors for over a decade at companies including finnCap and Commerzbank.

Smarkets have also hired Chris Baldacchino as Chief Compliance Officer. He joins after holding the same position at Hero Gaming, having previously been COO at the Malta-based firm.

The quartet join CEO and Founder Jason Trost on the company’s executive team.

Trost said: “I’m delighted to welcome Robin and Chris to the company, as well as adding two of our most dedicated employees, Céline and Tom, to the executive team.

“Robin, having been a team lead at Smarkets previously, is well-placed to develop and advance our class-leading product further, while Chris’s industry expertise will be invaluable as we look to expand to new territories, such as the emerging US market and other European countries.

“Both Céline and Tom are integral employees who have been with the company for many years and fully deserve their promotions, having played a big part in our recent success.”

The C-suite announcement comes shortly after Smarkets revealed that it had over £150m of trading volume on its exchange during the recent Cheltenham Festival, with all-time records broken for concurrent users on both the company’s web and app platforms.
