Five steps from a problem to its solution.

Help me design and build a first working prototype for this problem in Bengaluru, Karnataka, India.

Problem: Parents in Karnataka whose children have settled abroad have few easy ways to find company and support as loneliness sets in.
Who it hurts: Middle-aged and older parents, mothers especially, living alone or as a couple after their children emigrated for work or study.
The moment it hurts: The months after a child's visa comes through, when daily conversations become weekly video calls and evenings are spent alone in front of a screen.
What people do today: Parents lean on phone calls with their children and on streaming, and rarely seek help; support for 'empty-nest' parents is informal and hard to find.
Why it is still unsolved: Loneliness isn't seen as a health problem, groups for parents in this situation are scattered and unlisted, and the study itself is small and cannot show what causes what.
What solved looks like: A simple, Kannada and English service that connects parents of emigrated children to nearby peer groups, regular activities and volunteering, checks in by phone each week, and points those with signs of distress to free counselling.
Where: Bengaluru, Karnataka, India

First, list what you would need to learn from the people affected before building, as interview questions.
Then propose the simplest version that would help, the screens or messages it needs, and the data it would use.
Keep it cheap to run, accessible, and respectful of people's privacy. Flag anything you are unsure about instead of guessing.
