Chinnaraja (right), 38, set up Branded3 in 2003 with former freelance SEO consultant Altoft (below), 33, coming on board four years later to set up the Yorkshire agency’s SEO department, initially as a separate company before the two merged in 2011.

altoftThe pair quickly grew Branded3 into a 50-strong agency with billings of £4.1m, and last summer it was acquired by St Ives in a deal worth up to £25m. Just over £14m of that sum is linked to performance up until 2016, so both Chinnaraja and Altoft continue to lead the company at its Leeds HQ.

Clients include Virgin Holidays, BMW and Yorkshire Building society, and last year the agency also established a London office.
