Shout Digital has welcomed former Sage CEO Paul Walker to the business as an investor and advisor to its board.
Walker, who was recently announced as chairman of the new NorthEast LEP, spent 16 years as chief executive of FTSE100 software firm Sage.
He joins Shout founder Gary Boon - who developed the chip&pin system and the BBC licensing website - and directors Ian Baggett and Jason Mackay on the board.
The 10-strong digital agency has been in business in Newcastle for a year and hopes Walker's investment and input will "catapult" it to further growth.
Boon said: "The addition of Paul as a lead advisor is invaluable to Shout Digital and where the agency is headed in terms of development.
"Paul brings unparalleled knowledge from a business perspective and as former chief executive of one of the most well known PLCs in the software space."
Shout will open an additional sales office in London as part of its plans for growth.
Walker said: "My passion lies in helping to build successful businesses and investing in people rather than just their ideas.
“Shout Digital has enormous potential and I am passionate in helping the company grow and achieve its ambitions in the future development of digital space.”
