The backbone of
Indonesian
business payments.
We've built the modern rails that connect global capital to local markets. Licensed by Bank Indonesia and trusted by 600+ businesses to move money with zero friction.
Built because moving money in Indonesia was too hard.
Indonesia has one of the most complex payment landscapes in the world — dozens of banks, multiple e-wallets, fragmented rails, and processes that haven't caught up with how businesses operate.
Jack was built to fix that. A single place to manage all payment needs — local transfers, international payments, API disbursement, FX conversion — backed by real licensed banking infrastructure.
We're part of the Transfez Group, combining the reach of an established financial services group with the speed of a payment-first product.
Licensed. Regulated.
Bank-backed.
Licensed by Bank Indonesia
Jack operates under a Bank Indonesia money transfer licence (No. 13/77/DASP/30). Every transaction processed within Indonesia's regulatory framework.
Backed by a licensed bank
Your business account is held at one of Indonesia's largest licensed banks — not a pooled wallet. Real account numbers, real regulatory backing.
ISO 27001:2022 certified
Your data, transactions, and customers are protected to international security standards.
Two products.
One group.
Jack is the B2B payments arm of the Transfez Group — built specifically for businesses and developers.
Jack
Payment infrastructure for businesses. Run local and international transfers and virtual accounts via platform or API, with API FX conversion to IDR — all seamlessly integrated with business banking, in one place.
Transfez
International money transfers for individuals. Send from Indonesia to 70+ countries, or from Singapore to Indonesia — fast, transparent, and cheaper than your bank.
Backed by global investors
who know fintech.
From Y Combinator to MUFG — investors behind some of the most important financial infrastructure companies in the world.
What we believe
about payments.
Infrastructure, not a gateway
Real accounts, real rails, your name on every transaction. We're not middleware — the difference matters at scale.
Transparency by default
FX rates, fees, and recipient amounts visible before you send. No hidden markups discovered after the fact.
Simple to start. Serious at scale.
An SMB can get started without a technical team. A fintech disbursing millions a day trusts the same infrastructure.
Real people, reachable
Our team is on WhatsApp. Whether you're negotiating an FX rate or troubleshooting a webhook — a real person responds.
