Gaining Momentum

Refillable (refillable.store) is a verified Indian startup (Shark Tank India alumni) addressing single-use plastic waste through mobile refill trucks and IoT dispensing technology. While the project demonstrates high real-world utility and has verified backing (Third Derivative, government grants), the submission itself was of extremely low quality, providing hyperbolic claims ('everyone', 'most people have used my product') and missing data. The score reflects the project's legitimate operational status and market relevance, heavily penalized for the lack of verifiable evidence provided in the application and its currently localized scale (Mumbai/Bangalore) compared to established global players.

Description
Refillable is a zero waste refill service. We help brands deliver their products in a zero-waste format and help consumers shop consciously.

This directly translates in eliminating packaging and distributor costs, hence we pass on the cost-benefit to the consumer. The aim is to make sustainability convenient and affordable for users! We plan on creating a fleet of zero waste vehicles and eliminate single-use packaging at the source for consumers. Our secret sauce: from day one we co-develop the packaging and distribution technology to the precise requirements of each brand. We use IoT Machine, electric tricycles and a platform to provide safe secure distribution, at the lowest price with maximized con
