Marqeta — Architecture Analysis
Marqeta vs. Direct Card Issuing
Marqeta is the dominant card issuing processor for embedded finance. At early stage it removes significant complexity. At scale, the processing fee on top of interchange creates an economics gap that direct issuing relationships close.
| Dimension | Marqeta | Direct Card Issuing Processor |
|---|---|---|
| Processing model | SaaS + per-transaction fees on top of interchange | Direct relationship — interchange minus fixed spread |
| Platform advantage | Best-in-class developer APIs, JIT funding, real-time controls | Lower total cost at scale; more flexible commercial terms |
| Time to first card | Fast — Marqeta sandbox available immediately | Slower — direct processor agreements take 3–6 months |
| Interchange net | Interchange minus Marqeta processing fee (5–15 bps) | Interchange minus direct spread (2–5 bps) |
| JIT funding | Yes — core Marqeta capability | Requires custom implementation |
| Right for | Complex card controls, JIT, real-time spend management | High-volume programs where processing cost is the primary constraint |
Marqeta's real value is its technology, not its pricing. Just-in-time funding, real-time card controls, and developer-grade APIs are capabilities that justify the platform fee for programs that actually need them. The migration question is whether your program needs these capabilities at the volume where the economics gap becomes material — or whether a more direct processing relationship with fewer controls is sufficient.
