Data analyst internship

West Hampstead, London

A bit about us

Callaly is on a mission to inspire people with periods to expect more from their products, by finally putting customers’ needs first. We use innovation to transform the industry, reinventing products and the way they are bought. We invented tampliners, the first real design innovation to tampons in 80 years, which have won several prestigious innovation awards. We also offer a full range of organic period products – including tampons, pads and liners – all available via customisable online subscription. The Independent named us one of the “period-positive startups revolutionising the multi-billion pound feminine care industry” and we made it into Dezeen’s top 10 most forward-thinking designs for women. After expanding our range in 2019 we’re at an exciting time in our journey, building our team to help us grow without compromising our values.
