The Challenge

Hong Kong's no-cook culture meets a market that moves food—not cooks.

~80%

Busy, kitchen-shy

rarely cook under work pressure

59.3%

Eat-out vs healthy

eat out 4+ days/week, 62% hard to eat healthier out

Market gap

Delivery moves food, not cooks.

The Process

01 Research

Personas on both sides: diners (Ricky, Ada) and chefs (Daniel) mapped as one marketplace.

Research personas — Ricky, Ada, and Daniel

02 Product

Search → customise meal → book → pay, plus live lessons and trust signals (verify, reviews).

System Architecture & User Flows

03 System

Brand, mascot, and a Figma design system built to scale.

The Impact

Validated end-to-end booking flows and a hi-fi Figma prototype before build.

Clarified a two-sided marketplace: diner convenience and chef autonomy in one product.
