Lewis Blitz and brothers James and Richard Gold launched their first product – a colourful iPhone case aimed at young women – in 2011. After renting an office in Wembley and cold calling retailers, they got their first break when River Island put in an order for £20,000. The three founders, who appeared on the BBC’s Dragons’ Den in 2012, now employ more than 180 people worldwide, with about 70 based at their Londonheadquarters. Skinnydip’s range has grown to include handbags, clutch bags, sunglasses and jewellery.
