Many commercial and restaurant kitchens are under-utilised. The model is outdated - one kitchen serves one brand. So we’ve fixed this. On the demand side, we’ve created a multi-cuisine range of delivery focused food brands, so kitchens can serve more local people on more occasions. And on the supply side, our tech platform digitises kitchen operations to make them efficient. But what makes Kbox really special is the advanced analytics. We help kitchens find the right set of food brands for their market, and then optimize the mix – all without them needing a data scientist. So kitchens are busy and profitable.

Genie helps fast-growing Shopify brands take control of their inventory - tracking, planning, and ordering in one platform that takes minutes to set up and saves hours every week. Over 300 merchants rely on Genie to stay in stock, reduce manual work, and scale operations with confidence. We built Genie in 2022 to make inventory less painful for modern e-commerce teams - and it’s grown into one of the most loved tools in the space. Brands we’ve worked with include Leni Swim, Underdays, Just Wears, Onewith, Lealfre, Rise & Fall, Hommes Oro, Wyde Footwear - and hundreds more. In July 2025, Genie was acquired by Doss.com to accelerate our mission even further.
