Irish food firm Strong Roots has struck a deal to stock 2,000 Walmart stores across the US.

It doubles the number of US shops stocking products by the company, and brings its number of global stockists to around 8,000.

Strong Roots, which specialises in healthy frozen foods like sweet potato fries and plant-based burgers, was founded in 2015.

Today it is stocked by all major retailers in Ireland and the UK, bar Aldi and Lidl, and has a growing presence in the US and Middle East.

Last year it raised $18.3m in Series A funding, and is aiming for sales of $100m by 2023.
