Our Story
Why we started Griner
Cross-border eCommerce has endless potential. But for years, merchants have been forced to work with giant acquirers. That means rigid contracts, chatbot mazes, hidden fees and no one who actually answers the phone.
We saw a better way.
Griner combines big institution capability with boutique service. A partner, not a processor. Expert guidance, not automated tickets.
We built Griner for merchants who are tired of getting lost in the shuffle. For businesses that want payments to accelerate growth, not slow it down.
