What you could build

A local errand/gig platform — urban professionals pay neighbors or students for small favors (groceries, document runs, pet walks, assembly help). Think TaskRabbit but hyperlocal and low-cost, monetized via 10-15% platform fee. Works in apartment-heavy cities like Bangalore and Pune where people have money but no time. Or: A political loyalty app — candidates collect "favors" (commitments) from voters in exchange for policy promises. Voters track whether the elected official delivered. Turns "favor" into accountability infrastructure, monetized through political parties as campaign tools. Indian elections are hyper-personal; this replaces the old-style booth-level booth-level worker apps with a public-facing commitment tracker.
