KERALA RISING · FROM EXPORTING PEOPLE TO EXPORTING IDEAS The revenue side The revenue lines are the program-agnostic set introduced in Chapter 5 and Reward Partner subscriptions, patron contributions, discovery and referral fees, corridor and EPR sponsorship, department and tourism-board contracts, and audited data products. The crucial property for the model is that they are shared across programs and grow with corridors, so revenue scales with the breadth of the rollout while the build cost is paid only once. The model treats Tourism Excellence as the strongest direct earner, cleanliness as the builder of the Reward Partner and patron base, and Volunteer and Healthy as public-value programs likely to be cross-subsidised; a portfolio, not seven identical earners. Three scenarios The model runs three scenarios over a multi-year horizon from first capitalisation. They differ in how fast corridors activate, how readily Reward Partners and patrons sign on, and how quickly the data products mature. All three share the same cost structure and the same trivially small inference line; what varies is the speed of the revenue ramp.
