Former rugby player Adam Raby took the plunge as a fashion entrepreneur in 2014 when he founded swimwear brand Mazu. Raby adopted the name of the Chinese goddess of the ocean as a tribute to Hong Kong's fishing and maritime heritage - a branding decision that has brought good fortune to the business. Mazu has currently more than 30 stockists across Asia and it is enjoying double-digit growth each year. Hong Kong native Raby is also giving back to his home city and its surrounding seas. He designed a special-edition pair of trunks for the Hong Kong Dolphin Conservation Society and donates 10 perfect of the profits to them.
