Clinkle

Clinkle is a software company that developed a mobile payment app for smartphones. The app, launched in 2014, aims to simplify the payment process by allowing users to make transactions through their phone without the need for physical cash or a credit/debit card. Clinkle's platform uses a unique sound-based communication system to facilitate transactions, which has been praised for its security benefits. In addition to mobile payments, Clinkle also offers features such as loyalty programs and special offers to incentivize users to use the app. Despite a large amount of initial investment, Clinkle faced challenges in its early years, including leadership changes and criticisms of its lack of transparency. As of 2021, the company appears to have shifted its focus to enterprise software solutions rather than consumer-facing products.
