Co-Founder

Eazy Cheez

Co-founded a hyper-local food & delivery platform — a “Zomato for tier 2 & 3 cities” — built on a non-commission model to help restaurants, grocery stores, and vendors deliver within a 2 km radius.

The 2 km constraint and freelanced delivery model kept costs low for price-sensitive markets across Indian tier 3 cities. A custom algorithm was built for efficient order-to-delivery allocation.
