Beattie Financial has a fee income of £350,000 and specialises in financial comms for small to mid-cap companies. Clients include electronic data storage company Acal and Compass Finance.
Beattie CEO Gordon Beattie said: 'We have tended to work for larger multinational clients, and the fit with a City practice focused on smaller companies wasn't there.'
Beattie Communications still handles corporate and financial comms for AIM-listed RAM Investments and industrial cleaner firm Zenith.
