Stablecoin Native Full-Stack Fintech
Kevin Kang, co-founder of Reap, on stablecoin-native business models in fintech
This reveals that stablecoin fintechs work best as a full stack, not as a single feature. Once a company keeps its ledger in USDC or USDT, every adjacent provider, card issuer, treasury tool, savings product, and payout rail, has to understand those balances natively or the company is forced into constant conversion, reconciliation, and compliance work. In practice, the pain is not branding as crypto, it is operating a business on one money system while vendors expect another.

Reap is being used most heavily in places where traditional providers are harder to use, especially Latin America, Africa, and Southeast Asia. In those markets, stablecoins are less a niche asset and more a way to get reliable USD value, faster cross border settlement, and card and account products that local infrastructure often cannot support well.

The operational issue is the ledger. If payroll, vendor bills, and card spending all start from a stablecoin balance, mixing in fiat only tools creates manual off ramps, separate books, and slower settlement. Rain describes the same pattern, with crypto native customers consolidating spend on one stablecoin stack because otherwise accounting and treasury become fragmented.

This mirrors the older BaaS market, where fintechs assembled tightly integrated stacks of issuer processors, sponsor banks, KYC tools, and ledgers. Stablecoin infrastructure is rebuilding that stack with different primitives. The winning providers are the ones that let a fintech launch cards, payments, and treasury together, instead of stitching crypto and fiat systems together one by one.
The next phase is a broader stablecoin native financial stack, where money movement providers expand into cards, treasury, savings, lending, and programmable workflows. As more mainstream platforms add stablecoin support, the advantage will shift from simply offering access to stablecoins toward owning the cleanest end to end operating system for businesses that already keep their books in them.
