Fintech programs fail at the
architecture layer,
not the product layer.
The program model, bank structure, and economics are defined before the product is built — or they are defined by whoever you talked to first. ExpandUp architects the embedded finance program before vendor selection begins.
First conversation: 30-minute architecture diagnostic. No cost. No commitment.
The situation most fintechs are in when they call us
"We want to launch a fintech payments product but haven't defined the program model"
BaaS, direct MTL, or hybrid — the model decision determines your margin ceiling, compliance exposure, and long-term flexibility. It needs to be made before the first vendor call.
"We're building a payments feature and have already talked to a BaaS provider"
You've had the demo. The economics haven't been modeled. The program model hasn't been defined. Vendor selection happened before architecture.
"We launched on BaaS and the unit economics aren't working at our current volume"
BaaS pricing that worked at $10M monthly becomes untenable at $50M+. The model needs to be stress-tested against your volume trajectory and restructured before scale makes it harder.
"Our interchange is lower than projected and we don't know why"
BIN structure, card type, Level 2/3 data transmission, and revenue sharing terms were all set by vendor defaults. None of them were designed. The gap is recoverable.
"We need a sponsor bank and don't know how to structure that conversation"
Walking into a bank conversation without a prepared program model, compliance framework, and commercial term requirements means the bank's defaults define your economics.
"We're building a card program and compliance requirements keep surfacing mid-build"
KYC/KYB design, BSA/AML obligations, and bank examination requirements need to be defined before infrastructure is selected — not discovered after contracts are signed.
We sit between the program and the infrastructure.
We are not a vendor. We are not a broker. We do not refer fintechs to banks or take placement fees. We design the program — and then help you execute it. We sit on your side of the table. Our mission →
Six capabilities. One architecture.
When fintechs work with ExpandUp
Fintech programs that skip revenue architecture are leaving interchange, float, and fee revenue in the infrastructure layer.
The interchange capture structure, float economics, and fee design are decided at the architecture stage. Most fintechs inherit vendor defaults on all three — and the economic ceiling gets locked in before the program launches.

Design the program before the constraints lock in.
Every fintech embedded finance program starts with an architecture decision. The question is whether you make it intentionally — or let the first vendor make it for you.
