My Food Bag the grocery delivery service - founded by reality tv star Nadia Lim, former Telecom chief executive Theresa Gattung and Cecilia and James Robinson - has been partly sold to private equity group Waterman Capital.
My Food Bag delivers a week's worth of recipes and ingredients throughout New Zealand and in Sydney and Melbourne.
Speculation earlier this week of a full sale valued the company at $80 million.
Co-founder Cecilia Robinson described the deal as a partnership.
As both companies were private no details on the size or value of the stake would be released, she said.
