Gretta featured in Forbes' 30 Under 30 last year, recognising her entrepreneurial skills. In 2012, at the age of 22, she founded SkinnyMe Tea with just $24 in the bank and got it to $600k in just six months. SkinnyMe Tea became a global success and five years on has sold over 11 million cups of tea worldwide. She went on to launch brands like Dropbottle, Skintox Co, and The 5TH Watches (which achieved $1m in sales in one day), all leveraging the power of Instagram and social influencer campaigns.

Gretta’s most recent venture is an influencer marketing platform called Hey Influencers which helps to link and grow relationships between brands and social media influencers.
