About Keltasis
Payments people
building for merchants.
We run a gateway and acquiring service on Mastercard Payment Gateway Services (MPGS) for online businesses that need higher approvals, local reach and a partner who answers the phone.
What we believe
Every declined payment is a lost customer.
Our team comes from acquiring banks, PSPs and high-volume merchants. We built Keltasis on Mastercard's gateway platform and around the metric merchants care about most: how many good payments get through.
- Approval rate first. Every product decision is measured against it.
- Transparent pricing. Interchange++ so you never wonder where the money went.
- Human support. A payments specialist, not a ticket queue.
- Fast onboarding. Clear requirements and a decision in days.
