Our Team

Our software’s outstanding, but it’s our people and all of their commitment and passion that our clients keep coming back for. A partner by their side, who’s just like them and genuinely cares about getting the problem solved. Meet our core team…

Lee Bryant, Managing Director

Lee’s been with Sesui since 2006 when he joined as MD. And we’ve grown year-on-year ever since. A born problem solver, with 30 years’ industry experience in companies including Cable & Wireless Communications, Anite Networks, Cray, Dowty and Case Communications, Lee’s keenness of a good conundrum has helped transform voice communications in countless businesses, government bodies and healthcare organisations. And he admits he might just love Arsenal as much as he loves a fiendish Sudoku. But only just.

Julian Sammells, Head of Sales

With more than 30 years’ experience working in sales and management for software companies including Eptica, Merant, Continuus, Softool, and almost a decade focused on the contact centre and client service space, there aren’t a lot of challenges that Julian hasn’t seen and solved. Out of hours, he prefers the challenge of the wilds, living in the Yorkshire Dales and tackling the hills on his mountain bike.

Oli White, Head of Commercial

From start-ups to global conglomerates, including Tokbox, Telefonica and Cable and Wireless, Oli’s 20-year track record in technology marketing is helping Sesui cement its leading position in cloud communications. Oli’s appetite for winning continues out of the office, coaching junior rugby and cricket with his kids, and when injuries permit, taking to the field with the grown ups too.

Manveer Mangat, Chief Technical Officer

For over a decade, Manveer’s built his reputation as an expert in voice communications innovation and design. With a track record in network operations, security management, product development, technical support and partner management, these days Manveer can design his way around the most complex client problems. With two young sons, Manveer’s problem solving at home is no less complicated or rewarding!

Mike Levey, Head of Professional Services

Mike joined Sesui in 2009, bringing 25 years’ experience in voice and data, having worked with carriers and network integrators including Cable & Wireless, Case Communications and Anite. Mike’s well versed in the challenges of managing vast, complicated global client programmes and project teams. He says it’s that experience that’s made him the calm and organised operator that he is today. Outside of work Mike enjoys time with the family, travelling and sport, ideally combined with a real ale.
