LoyaltyLion is a data-driven loyalty and engagement platform trusted by thousands of ecommerce brands worldwide. Merchants use LoyaltyLion when they want a loyalty program that is proven to increase customer engagement, retention and spend. Stores using LoyaltyLion typically generate at least $15 for every $1 they spend on the platform.

Today LoyaltyLion works with over 10,000 small and medium sized retailers. Our mission is to help them 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.
