Who is behind this

portrait of Gonzalo Reyes

Gonzalo Reyes

Founder of TUN

“I have been at the whiteboard and in the war room.”

Payments architect and technology leader. A career built at the intersection of retail, fintech and payment methods — developing transactional systems, integrating acquirers and broadening the use of payments, in person and digital.

Worked in banking, and later as a technology services provider, which means many companies and widely different lines of business — retail, banking, health, education, fuel, pharmacy and financial services. Each with its own business logic, all of them learned from the inside. Has built systems for Chile’s leading card acquirers, integrations for the region’s largest retail chains with a presence in Chile, Brazil, Mexico and Peru, and digital payment and processing systems for a financial conglomerate in Peru.

Now, with AI redefining every layer of technology delivery, there is a new opportunity: to build with the rigour of architecture, yet at the speed of AI-augmented delivery, transforming businesses as it goes.
