BT chief executive Ian Livingston and his Next counterpart Simon Wolfson hosted a lunch for 45 business leaders at the BT Tower in support of Herts Jewish secondary school Yavneh College.
Introduced by educational philanthropist Benjamin Perl, Chief Rabbi Lord Sacks spoke glowingly about Yavneh's achievements.
Mr Livingston also addressed diners, as did headteacher Dr Dena Coleman and pupils Talia Jay, Richard Reback and Liz Drey on different aspects of school life.
Mr Livingston praised Yavneh as "a shining example of excellence. In a few years, it has shown how a school can really develop the potential of pupils across a wide range of activities."
Governors' chair Malcolm Gordon said the intention had been "to communicate to our key supporters in business just how much Yavneh College has already achieved in a short space of time".
