About Snaplii

Snaplii is one of Canada's fastest-growing fintech platforms, transforming how people pay, save, and earn rewards. With over $200M in annual transaction volume and 400,000+ users across North America, we deliver unmatched utility through a single seamless app. We consistently rank among the Top 40 Finance Apps on the Apple App Store, powered by a highly engaged user base and partnerships with more than 500 leading brands, including Costco, Walmart, Amazon and Uber.

Behind the scenes, Snaplii operates real payment infrastructure at scale. Together with our merchant payment business, our platform supports thousands of merchants and processes billions of dollars in transaction volume across North America.
