React jobs at Mercato


About Mercato

Mercato is marketplace empowering independent grocers – a $131B annual category in the US – to finally have an online presence. Their platform gives merchants access to a nationwide delivery network, marketing tools, customer analytics, and customer membership programs, while customers can access to their favorite stores and incentives / offers that are otherwise unavailable.

Mercato was founded in 2015, inspired by experiences Bobby Brannigan had growing up working at his family’s independent grocery store in New York. He realized first-hand that the 40,000+ independent grocery stores in the US lacked the technology and infrastructure to keep up with the modern demands of consumers driven by e-commerce experiences.

Today, Mercato has acquired hundreds of thousands of customers as well as thousands of merchants (two-sided marketplace), all while maintaining an NPS score of 70+ (benchmark for grocery is 39). This is the 2nd marketplace built by Bobby Brannigan, who previously founded ValoreBooks while in college (2002), which reached $100M in sales, and was acquired by SimpleTuition in 2012.
