The TechFuture Women’s Network is a large network female tech professionals from across sectors, who volunteer their time to inspire young people, particularly girls between the ages of 14-19, about tech careers and education pathways.
Members visit schools and take part in a range of activities, including giving talks, leading after school clubs and running careers workshops.
