Here are some potential product/service ideas to address the needs of the customer personas provided:
For Michael: Guided tour packages for solo travelers over 65 to popular destinations
For Jenny: Fitness classes tailored for active seniors, childcare services for grandparents
For Robert: Light meal delivery service for seniors living alone, transportation services for medical appointments
For Desmond: Multi-day hiking/cycling tours for active retirees, educational workshops/classes on topics of interest
The ideas aim to provide social activities and services that address needs around travel, fitness, independence, and lifelong learning for older adults with varying interests and abilities. Getting feedback from customers would help refine the concepts.
