The business was founded in 2014 by Andrew Wilson, a former RBS head of comms who worked at WPP prior to setting up Charlotte Street Partners, and the ex-director of comms for airport operator BAA in Scotland, Malcolm Robertson.
Last month the firm appointed investment analyst Tamsin Garrity, who joins from UBS, as partner and head of financial comms and investor relations, to build an IR offering on top of the agency's existing financial practice. Garrity will be based in London.
Jo Nove has been promoted to the role of partner and head of client services having joined the firm initially five months ago from the agency Greenhaus Communications, a Scottish public affairs agency whose clients include Johnson&Johnson, HSBC and Coca-Cola. She relocate from Amsterdam to be based in Edinburgh and will lead the firm's new healthcare practice.
The firm's board includes Rudd's colleague at Finsbury, James Murgatroyd, as well as The&Partnership founder Johnny Hornby.
Robertson said of the agency's new divisions that it wanted to "scale and extend our offer carefully".
He said: "We are putting significant investment into the growth of the company as we prepare for the next phase of our growth. It is always a challenging market but it is also hugely enjoyable, as we build an outstanding team."
