Training firm Mind Gym is planning to flex its market muscles through a £140m listing on London Stock Exchange arm AIM.
The company, which is owned by Octavius Black, an Eton peer of former Prime Minister David Cameron, has brought in Liberum Capital to handle the listing. City A.M understands that an announcement on the float is expected in the next few days.
Mind Gym uses behavioural science to encourage its client's staff to go about work differently and approach problems in innovative ways.
Ownership at the company is split between Black and occupational psychologist Sebastian Bailey, who founded both the business in 2000, as well as Black's wife, Joanne Cash who has served as the company's chair since 2014.
The company employs 250 coaches around the world who host 500 "workouts" for middle managers per week.
It has worked with Microsoft on tackling the tech giant's overly competitive culture and encourage workers to collaborate through programmes like "managing for impact" and "giving actionable feedback".
At insurer Zurich, Mind Gym were also drafted in to create a more united leadership approach after a raft of mergers and acquisitions caused disruption across the company's workforce.
It has also worked with the likes of GSK, Unilever and Maersk on staffing problems.
Overall, Mind Gym says it has helped 62 per cent of the FTSE 100 and over half (59 per cent) of the S&P 500 tackle major problems with their workforce.
