At Explorex, we’re reimagining how India dines.

We’ve built Elite – India’s first self-checkout and dining experience app – that lets diners skip the wait for bills, see live table availability, browse live menus, and unlock tiered discounts that encourage more discovery and higher spends.

Behind the scenes, Bridge OS – our proprietary restaurant operating system – powers everything from POS to payments, guest data, inventory, and insights. This deep integration makes Explorex not just another software, but the backbone of a restaurant’s in-dining business.

Our mission is simple yet bold:
To revolutionize the $100B+ in-dining market by creating a seamless, delightful experience for diners while unlocking higher revenue and operational efficiency for restaurants.

Today, Explorex is helping restaurants thrive while shaping a new culture of dining where convenience, transparency, and guest experience come first.
