Olympic event rider Robert Lemieux and his wife Lisa started selling supplements for horse health from their van in 2003. Since then, the LeMieux brand has become one of the fastest-growing British equestrian and lifestyle brands in Europe. In March 2021, LeMieux raised £20.8m in equity funding to support its international expansion and to grow its product range. It currently has distributors and retailers in Europe, Scandinavia, the US, Australia, Canada, and New Zealand. The Hampshire-based company continues to grow, hitting turnover of £36.8m in 2022, up 62% from the previous year.
