Java Developer

Why Reelo

In today’s customer-centric world, small and mid-market F&B and retail businesses need to market like the best brands — but collecting, understanding, and acting on customer data is often complex, expensive, and time-consuming. Solving this is why Reelo exists.

Reelo is a new-age customer marketing platform that helps restaurant and retail businesses grow revenue, acquire more customers, and build stronger brands — simply and effectively.

While it’s easier than ever to start a business, it’s harder than ever to grow one. Most businesses struggle with two things: getting customers to make their first purchase, and getting them to come back again and again. Reelo makes this easier by enabling smart, automated customer engagement without adding to already overloaded teams.

We’re building something big, meaningful, and lasting — and we’re looking for curious, driven people who want to do purposeful work and grow together.
