LONDON—Nelson Bostock chairman Martin Bostock is to retire from the business he founded with Roger Nelson in 1987. 

Bostock, who is 61, has led the group for 28 years since its lauch as a consumer tech and telecoms agency. He steps down at the end of March.

Nelson Bostock was sold to Creston in 2003, and the group now includes the main tech/B2B agency Nelson Bostock; consumer agency, Fever; digital/social shop Things Unlimited; and content creation agency MediaWorks.

"When I look at our client list today, at the ground-breaking work the agencies produce, at the awards we’ve won and at the talent of the people within the group, I find it hard to reconcile with the memory of Roger and me setting up with an Amstrad word processor and a fax machine in an attic on the Portobello Road," said Bostock.

Bostock's co-founder Nelson retired in 2007, while Bostock has reduced his involvement in the group in recent years, becoming non-executive chairman in 2013. Nelson Bostock is led by group CEO Lee Nugent, supported by Fever MDs Bruce McLachlan and Frankie Oliver, and Nelson Bostock MD Nick Clark.

"He’s been a terrific coach and mentor and remains a great friend," said Nugent. "Even though he won’t be physically ‘inside’ the organisation any more, Martin’s spirit, personality and relentless command of great grammar will remain imprinted on the Group forever."
