How to offer faster payment rails for businesses (build vs buy for founders)
Been sketching a b2b saas idea that would need cross border payments as a feature. Quick founder question, how to offer faster payment rails for businesses as part of your platform without going broke on licensing.
You don't build rails yourself, that's like a 5 million dollar two year project for a solo founder, which is impossible. You integrate with backend infrastructure providers that handle licensing, custody, compliance, settlement. The main ones for b2b payment platforms are cybrid (US and canada, ach pull, good sandbox), bvnk (multi rail, stronger European coverage), bridge (stripe bridge since early 2025, clean developer docs, post acquisition roadmap is stripe-aligned), zero hash (custody and settlement primitive for fintechs adding crypto features), and conduit (latam heavy).
The 2026 version of this is, you pick an infrastructure provider based on where your target users are, you build the platform ui and workflow on top, and the actual payment rails (including the stablecoin settlement layer for cross border) are invisible to your users. They just see faster cheaper international payments.
Founders I've talked to who tried to build this themselves got stuck on state msb licensing which is a multi-year slog. Every single one said "just use an infra provider". Does anyone disagree? Curious if there's any case where building makes sense for a <$100M revenue b2b platform.
