This week's lunchtime masterclass is with social media experts Cat Turner and Bridey Lipscombe of Native LDN.

Cat and Bridey met three years ago when they worked as head of social and head of digital at Rabbit, the 2012 social media agency of the year. Six months ago they decided to set out on their own and set up Native LDN - a social brand communications agency.

Since then they have secured clients across the world in London, Berlin, New York and Singapore. Their clients in the fashion sector include the UK's largest handbag producer Fiorelli and most recently Digital Fashion Week Singapore.

Before launching Native LDN, Cat co-founded political news website PoliticsHome and headed up the Lib Dems social strategy in the 2010 election. Bridey co-founded one of the first social media agencies and lead on campaigns that won eight industry awards, including the CIPR Award for best use of social media.

With a combined experience of almost a decade in the industry, they have worked on projects for a range of clients including: Secret Cinema, Pernod Ricard, Water Aid, Pret A Diner, Browhaus, Ministry of Waxing, Booths, Skinny Pizza and Digital Fashion Week Singapore.
