Meet the team

We're a friendly team where innovation, industry wisdom and a passion for customer experience come together

An experienced leadership team with technology at our core

Cornerstone has been providing services to its clients since 2010. Our founding partners had worked in the industry for many years and knew there was a better way to handle transactions.

With an expanded leadership team, we recently became a publicly listed fintech business. Today, we’re growing fast, with a focus on enabling small and medium sized businesses to manage payments and currencies seamlessly.
