About Us
At LoyaltyLion, we help Shopify brands increase repeat purchases with their own integrated loyalty programs, motivating shoppers with unique loyalty experiences. We provide the tools and expertise needed to drive growth through higher returning customer rates, better retention and greater customer lifetime value.
LoyaltyLion is the leading loyalty platform in our space - we were the first to integrate with Shopify and we are #1 on G2 today. Our mission is to help ecommerce brands succeed in the age of Amazon, where they may not be able to compete on price and logistics but can offer a better customer experience. An experience where customers feel valued, rather than just another number.
It’s been an incredible two years for LoyaltyLion. We closed $12.5m early last year and another $12m this year, and we’ve grown from 40 employees to over 100. We’ve built out our Leadership team, recruiting a CTO, CFO and Director of Product amongst other senior hires and we continue to scale quickly, achieving spots in both the Deloitte Fast 50 and the FT1000. This is just the beginning of our inflection point.
