One Day founders Sarah Jayne Fell and Delia de Villiers met working together at Design Indaba in 2012 on both the flagship conference and their online publication, which took over from Design Indaba Magazine. Delia was there as content manager from 2010 to 2013. Sarah joined from 2012 to 2015 as first content manager and then digital product manager. This included managing all digital properties including the main company website and online publication,, and the company’s two apps for iOS and Android, as well as other websites and digital projects such as Anotherlightup. She also started the company’s Instagram and Pinterest social media accounts, Wikipedia pages, wrote their in-house style guide and got them onto Mailchimp to manage their newsletters and contact database.

After starting One Day Company, from April 2015 until October 2017 Sarah worked on a consulting basis as One Day Company, project managing the digital team on development, web design and user experience as well as training new staff on content management and online publishing best practice. She occasionally writes for the website too.
