SkinnyDipped, a US better-for-you nut snacks firm, has revealed Colombian pop star Shakira has invested in the business.

The amount put in by the Grammy-winning singer-songwriter has not been disclosed.

Seattle-based SkinnyDipped, which uses ethically sourced ingredients, was founded by mother-daughter duo Val and Breezy Griffith.

Its products include its line of SkinnyDipped Almonds and its recently announced SkinnyDipped Cashews range. The snacks have a “super thin” coating of either dark chocolate or yogurt.

Made with non-GMO ingredients, the products are gluten-free and contain no artificial colours or flavours. They are stocked by grocers including Kroger, Safeway, Target and Whole Foods.

Shakira said: “I was hooked on SkinnyDipped almonds and chocolate (two of my favourite things, but with less sugar) from the moment I tried them, but when I learned about the brand’s mission and that it was founded by a mother and daughter duo, I was sold.

“Val and Breezy are true role models for other young entrepreneurs, and have made a product that is unique and socially conscious. Female leadership and social impact are things I’m increasingly passionate about, so investing in a brand whose values I believe in on top of loving the product made perfect sense.”

Breezy Griffith, SkinnyDipped’s CEO, said: “We are incredibly excited and grateful to have cultivated this relationship with Shakira, whose dedication to the nutrition and health of women and children around the world is well-documented and incredibly respected.

“We have the utmost respect for her as a performer and a philanthropist, and are honoured that she values our products and the work we are doing as much as our team does. This investment will support our mission and allow us the ability to make ethically-sourced, nutritious and delicious snacks accessible to more people.”
