What people say about us
We're proud to be a 5-star rated company on Google. See what people say about us.
My hope for the future is to experience women in technology as the norm. The early stages of my career in tech were shaped by women and I feel very privileged to count some of the best women in technology in my network of close contacts and friends. However, I know this isn't the case for many women in the sector, who find themselves outnumbered by the opposite sex. Anything I can do to challenge the current norm and break the stigma for Women in Technology, I will do.
