Marmite-owner Unilever has bought healthy snack brand Graze, which started life a decade ago as a snack box delivery service.
Graze produces nuts, seeds, trail mixes and snack bars, with no artificial ingredients and Unilever said the purchase would accelerate its presence in healthy foods.
The sale price was not given, though sources say it was less than £100m.
The boss of Graze described the deal as 'transformational'.
Graze products are now available in stores including Sainsbury's, Boots, WH Smith and Tesco, as well as online and direct to the consumers.
The business was set up in 2008 by seven friends as an internet-based business. In 2009, Anthony Fletcher joined the company
In 2012 Mr Fletcher led a management buyout and became chief executive of the company.
The move, which was backed by US private equity group Carlyle taking a majority stake in the business, saw three of the seven co-founders end their day-to-day involvement in the business but remain as shareholders.
Mr Fletcher said the sale to Unilever "marks a transformational moment in Graze's growth journey".
"We look forward to working closely with the team to keep on inventing new healthy snacks, as well as continuing to work to understand the role technology can play in improving the food industry," he added.
Nitin Paranjpe, president of Unilever's food & refreshment business said: "Accelerating our presence in healthy foods and out of home this is an excellent strategic fit for the Unilever Food & Refreshment business, and a wonderful addition to our stable of purpose driven brands.
Nick Cooper, of global branding agency Landor said: "Unilever has a good track record when it comes to purchasing and then nurturing smaller brands. Its innovation and investment incubators have given it expertise in growing those smaller, more entrepreneurial brands. That's why this deal makes sense for Graze.
Mr Cooper said in the short term Unilever would "likely leave Graze alone".
"That's certainly what it did with Ben & Jerry's".
However he added Graze would be able to "tap into" Unilever's global distribution channels and reach new customers.
