Trakm8 said on Friday that the extension was for the Sainsbury's Goods Online delivery solution, which was built on its Insight AI Optimisation platform algorithms supplied via API.

The AIM-listed group highlighted that since the introduction of Sainsbury's use of Trakm8 Insight AI algorithms, over 4,000 tons of carbon have been saved each year.

Chairman John Watkins said: "We are delighted to extend the duration of the solutions we provide to Sainsbury's having built a terrific solution together in partnership to give Sainsbury's customers the best possible experience from the GOL platform."

As of 0955 BST, Trakm8 shares had sunk 11.11% to 6.0p.
