What Are the Different Approaches to Launching a Credit Card?

A founder’s guide to the paths, tradeoffs, and decision points that matter

---

There’s more than one way to launch a credit card.

If you’re a fintech founder or early product lead exploring how to offer a credit product, you’ve likely discovered this already: there’s no single blueprint. Just a handful of viable paths each with their own infrastructure choices, regulatory implications, cost profiles, and long-term consequences.

This post breaks down the core approaches, the real-world tradeoffs, and how to think about them.

Approach #1: BaaS / Lending-as-a-Service Platform

This approach bundles together most of what you need to launch: issuing bank, processor, ledger, compliance, and sometimes even a white-labeled front end.

✅ Best for:

• Teams focused on getting to market quickly

• MVP or early-phase testing of credit features

• Limited internal regulatory experience or infrastructure capacity

⚠️ Tradeoffs:

• Higher per-account costs or revenue share

• Less flexibility on credit policy or UX

• Limited control over roadmap, data access, and vendor relationships

• Risk of platform issues affecting your brand

Approach #2: Sponsor Bank + Modular Stack (Build Your Own Program)

This approach involves working directly with a sponsor bank and assembling your own infrastructure stack: LOS, LMS, processor, fraud tools, payment processor, customer interface, and more.

✅ Best for:

• Fintechs for whom credit is a core revenue driver

• Teams with in-house product and engineering

• Need for product flexibility and custom UX

• Long-term economics and control matter

⚠️ Tradeoffs:

• More up-front complexity and cost

• More responsibility for compliance and vendor oversight

• Potentially longer implementation timelines (although not always true)

This is the path taken by serious fintech lenders—those who want to scale a differentiated credit product, not just offer a card.

Approach #3: Co-Brand or Private Label Partnerships

This model leverages a traditional issuer or bank to launch a branded card in partnership. Your company focuses on distribution and customer experience, while the issuer handles credit decisioning, servicing, and compliance.

✅ Best for:

• Brands with large, engaged audiences

• Companies looking to add a card without building full infrastructure

• Consumer-facing apps or marketplaces

⚠️ Tradeoffs:

• Limited visibility into underwriting, economics, and customer data

• Fixed revenue share terms

• No real credit product innovation—you’re layering a card onto your brand

This path can be powerful for consumer apps or DTC brands—but it’s not a fit for fintechs building core lending businesses.

Approach #4: Bank-Issued / In-House (Full Charter or Direct Issuance)

This is the traditional model used by large banks or fintechs with a bank charter: you issue under your own BINs, own the receivables, and run everything yourself.

✅ Best for:

• Mature companies with a charter or bank partner

• High-volume portfolios

• Full control over economics, compliance, and roadmap

⚠️ Tradeoffs:

• Immense capital and regulatory requirements

• Ongoing oversight from federal regulators

• Not viable for early-stage teams

Unless you’re a chartered institution or working closely with one, this is likely out of reach for most startups—for now.

A Note on Secured vs. Unsecured Credit

Regardless of your approach, you’ll also need to decide whether to start with:

• Unsecured credit: traditional revolving card, based on underwriting

• Secured credit: backed by a user deposit, often easier to launch but with different economics and risk profile

Some fintechs use secured cards as a stepping stone to unsecured. Others go straight to underwriting and unsecured credit lines.

How to Choose the Right Approach

Here are a few questions to help guide your decision:

• How core is lending to your business model? If it’s a major revenue driver, you likely need more control than a BaaS can offer.

  
  

• What level of ownership do you want over UX and product roadmap? White label may get you live faster—but with some limitations.

  
  

• Do you have (or want to build) internal credit and compliance expertise? If not, you’ll need a partner or advisory team to help you build the right foundation.

  
  

• What are your unit economics at scale? Per-account fees and revenue shares can kill margins if you don’t structure things properly early on.
