GeekGirl loves spending time with enthusiastic people, and this lady is one of the most passionate people we know! GeekGirl sat down with the Centre for Acceleration of Social Technology's (CAST) Ellie Hale, to talk ALL about tech for good, the key drivers of her career to date and to share her wisdom with you!

Ellie is fascinated by the potential of technology to transform lives, systems and mentality, and keen to promote those already doing it well. She is an Associate at CAST (the Centre for Acceleration of Social Technology), which helps social-impact organisations build scalable and sustainable digital tech.

As well as running the PR, marketing and events for this small but powerful 'tech for good' org, Ellie co-ordinates its Digital Fellowship: inducting senior nonprofit leaders into the world of technology, and helping them better understand and develop effective digital products and services.
