Surrey charity Satro received a £20,000 donation from charity Give-It-Away, founded by Putney entrepreneur Charlotte Grobien.
Ms Grobien presented a cheque to Satro chief executive Beccy Bowden, who said: "It is an honour to work with someone as inspirational as Charlotte - not only has her donation enabled us to reach many more young people and ensure they take their next steps to a promising career."
Give-It-Away supports small, local charities who work with vulnerable children and young people who have disabilities, learning difficulties and difficult home backgrounds.
The £20,000 donation will help Satro run the Mobile Construction Classroom at Woodlands School, Leatherhead, and support disadvantage students on their extended work placements, as well as offering careers and university advice.
Ms Grobien said: "I was delighted to meet Satro recently and to hear about the enormous number of programmes they are running in the Surrey area which benefit young people who may be unable to identify what their role in business and industry could be on leaving school.
"I am very committed to providing as much positive opportunity as early as possible for young people and am very pleased that my contribution will be put to practical use."
