Tribal, which provides support services to health, education and local authorities, believes it can take Atlas into new professional areas and help the firm grow beyond its base in the north of England.
Richard Chew, a company director, said that there were as yet no firm plans as to what areas of growth the agency would look to first.
Atlas, whose MD is Bob Schofield, was founded in 1993, employs 30 staff and is forecasting turnover over £2.5m this year.
