Venture philanthropy company the Impetus Trust is to invest £275,000 in the young people's conflict-resolution charity Leap Confronting Conflict.
The fourth charity to receive investment from Impetus, Leap Confronting Conflict will receive help with capacity building and management functions.
The charity has undergone assessment and has been the subject of a "sector and competition analysis" by consultancy firm OC&C, worth £75,000.
In the first year, Impetus will invest £80,000 and advise the charity on boosting administrative functions. It is hoped Leap, which works with youth gangs on estates and in prisons, will be able to accelerate its growth plan and increase the number of young people it deals with.
"We have been impressed by Leap's models for working with young people dealing with conflict, by their involvement of young people from disadvantaged communities and by their staff," said Judith Brodie, chief executive of the Impetus Trust.
