Grenade is one of the fastest growing brands in the massive sports-nutrition market. The brand was started by Alan and Juliet Barratt, who created their first product in their home kitchen in 2009, later launching the company with just £27 in their business bank account. Grenade now has customers in more than 80 countries, with plans to expand further after a huge stake in the company was sold last year to Lion Capital for £72m.
