Organised along similar lines to Young Enterprise schemes, Oundle Charity Venturers is a voluntary activity, which takes place on a weekly basis every Thursday. It is mainly for Lower Sixth pupils, but other groups are not excluded.

Pupils form companies comprising six to eight members, each bringing different talents suited to different roles, such as finance, ICT, product development, or communication; each member of the company is elected by the group to fill a post, such as Managing Director, Finance Director, Secretary or Marketing Director. The activity helps to develop leadership and teamwork skills. Pupils are expected to run their businesses as independently as possible, but all the financial affairs are run through the School.

Recent projects have ranged from events such as a (Pre)-University Challenge show, a Staff Cross Country Race and a Valentine’s Ball, to products such as a recipe book, beanies and lip balm.
