OZA began as a side hustle for two design-agency colleagues who craved “fresh-blended flavour freedom.” Today their on-demand blending studio holds more than 90 herbs, fruits and single-estate teas; café or corporate clients pick a base, tweak aromas and upload their logo for small-batch private-label sachets, dispatched within a week. Zero leftovers (because everything’s blended to order) and home-compostable wrappers keep waste to near-zero.
