Sebba and Harrisson have made arrangements to acquire at least six Tossed sites under their newly formed company BNW Food Limited (BNW) from administrators Quantuma.
BNW is also in discussions to secure several more stores and expects to create at least 50 new jobs in Central London by the end of September.
The pair were previously managing director and commercial director of Zest Food Ltd, which operated the Tossed and Vital Ingredient brands across a total of 20 sites.
However, in July Zest was placed into administration and all staff were made redundant following an unsuccessful trial reopening period in June where walk-in sales were heavily impacted due to Covid-19.
A soft (re)launch is being planned at Tossed's site in London's Clerkenwell next week.
Further locations are expected to open in the coming weeks, including a delivery kitchen at Foodstars Battersea.
“The last six months have been impossible for food service in London, and to see Zest go into administration in July was extremely difficult for everyone concerned," says Sebba.
“Angelina and I are delighted to be given the opportunity to save this wonderful brand, and hope to create at least 50 new jobs in the coming weeks.
"We are thrilled that Londoners will still be able to get their Tossed fix, either in person when they return to their offices or on delivery.
“No doubt the winter trading in London will remain extremely difficult as the Covid-19 situation unfolds, but we are working with a group of landlords and an administrator who have approached this crisis collaboratively.
"This is refreshing, and speaks volumes for the strength of our brand and our plans for its reopening and beyond.”
