Budget tea giant MIXUE has recruited an unlikely brand ambassador in Vietnam: Duo, the insistent green owl from language-learning app Duolingo. On 24 October, the two brands staged a tongue-in-cheek 'appointment ceremony' at Times City in Hanoi, where Duo — usually MIXUE's mascot Snow King's rival for the attention of Vietnamese Gen Z — was installed as the company's 'Director of Matcha' to front its new matcha product line.

The stunt fits neatly into MIXUE's latest financials. In its interim results announced on 27 August, the group reported revenue up 2.3% year-on-year, with franchising and related services revenue climbing 10%. As of 30 June it counted roughly 64,000 stores across 17 countries, and management says the strategy is shifting from pure store-count growth towards quality: better products, better in-store experience and sharper brand IP. Vietnam, with nearly 1,000 MIXUE outlets, is a key testing ground for that pivot.

The Duolingo campaign goes beyond a co-branded poster. At the Hanoi launch, visitors could meet Duo and Snow King in person and join games like saying 'I love matcha' in six languages. The digital-to-physical hook is the cleverest part: app users who keep a three-day-plus learning streak can redeem free matcha ice cream under the programme's rules, under the slogan 'Study paired with matcha'. More than 800 MIXUE stores nationwide are taking part.

Why does this matter to a traveller? If you're in Vietnam between now and the end of the campaign, it's a free, low-effort bit of local pop culture — the kind of quirky, youthful marketing that Vietnam's big cities do especially well. Duolingo stunts are Instagram catnip, and the Times City event format (costume characters, photo ops, games) is typical of how Vietnamese malls stage brand launches. Even outside the promo window, MIXUE outlets are worth knowing about: with locations on nearly every corner in Hanoi and Ho Chi Minh City, they're one of the cheapest ways to cool down, with fresh drinks and ice cream usually priced well below Western café chains. The matcha line is the newest addition to a menu built around soft-serve and fruit teas.

For brands watching from the sidelines, the campaign is a case study in localising global IP — pairing a Chinese budget-tea franchise with an American app mascot that Vietnamese students already use daily. For everyone else, it's simply an excuse to grab a green soft-serve and call it study time.
