This Manchester company designs software used by blue-chip companies to save back-office administration costs and comply with legislation on temporary agency staff and locums. Growth has followed an increase in workplace legislation since the company launched in 2010, and acquisitions of blue-chip clients helped lift sales to £60.3m in 2015. Neuven is led by chief executive John Simmonds, 49, who bought the fledgling company from its seven founders in 2012.
