Loyalty for bubble tea & drinks in Hanoi

Hanoi is a high-density, high-competition market for bubble tea & drinks. A single neighbourhood like Hoan Kiem can host dozens of direct competitors — most operating on the same delivery apps, the same price points, and the same generic loyalty stamps. The differentiation that wins here is not menu, it's memory: knowing which guest is about to drift, and reaching them at the exact moment they're considering somewhere else.

PEKO is built for that. We capture every guest at first visit through a Zalo OA QR, score them daily on RFM, predict churn 14–60 days ahead of cadence, and trigger personalised win-back automatically — typically lifting 90-day retention 10–15 points within the first quarter for Hanoi operators.

Hanoi's F&B scene leans seasonal — Old Quarter venues see ~35% guest-volume swing between winter and summer, making predictive win-back especially valuable before each shoulder season.

Hanoi guests respond well to scheduled morning broadcasts (7–9am) tied to weather changes. Zalo OA still leads; Facebook Messenger retains a meaningful long tail in Cau Giay and Dong Da. For bubble tea & drinks, that means the highest-leverage automation is usually the silent-guest win-back tuned to local cadence — not generic monthly broadcasts.

Hanoi bubble-tea is dominated by Phuc Long and Mixue in foot-traffic corridors, with independents surviving in study-corridor neighbourhoods like Cau Giay near universities.

TacticTerm-time digital stamp + 'study break' afternoon push to the student segment lifts Hanoi independents' weekday repeat 30–40% vs. broadcast-everyone baseline.
