Former city banker Nigel Harris has been appointed chief executive of New Philanthropy Capital.
His appointment heralds a change of direction at the organisation, which produces research to help donors spend their money more effectively.
It wants to reach out to more donors as well as carrying out its traditional role of publishing research, which has been the core of its work since it was founded three years ago.
Harris, who left Schroders to join New Philanthropy Capital in another role two years ago, succeeds Bernard Mercer, who has taken a new role within the organisation investigating the value of producing environmental reports.
The organisation has recruited two senior staff as part of its new direction.
Harry Charlton, who was previously head of private-sector development at the Prince's Trust, has become head of donor relations, while Jai Mukherjee has been appointed head of marketing.
"We want to increase our visibility with donors," said Mukherjee.
