Nature Delivered's brand Graze is hit the high street for the first time in 1,200 Sainsbury’s, Boots and WH Smith Travel stores today.
The online retailer is offering 12 healthier snacks in stores which include dried fruit, nuts, pretzels, and fruit flapjacks.
The company said it had already trialled the products in Boots stores, where they had delivered the highest rate of sales of any snack and had proved popular with customers who do not often buy snacks.
Sainsbury’s said it will position the “tasty and more permissible” snacks next to tills to target impulse buyers who might ordinarily by tempted by chocolate or sweets.
Owned by private equity group Carlyle, the company delivers snack boxes to thousands of customers in the UK and the US. Revenues grew by 31% to £68m last year.
The Graze brand was launched in the UK six years ago and now employs almost 500 staff.
