Traditional card issuing relies on legacy rails and weeks of integration work. Losing time to brittle APIs and opaque compliance shouldn't be the norm — yet for most teams, it still is. We built CelerX to make embedded finance feel like a modern developer product.

We're thrilled to announce a major upgrade to CelerX — designed to make onboarding and operating embedded card programs simpler and safer than ever. Born from our own need for seamless yet secure payment experiences, these features offer the easiest path to launching cards.

With features for builders and operators alike, CelerX makes interacting with modern card issuing secure, effortless and fun. Issue, fund, and control cards in minutes with a clean SDK and a delightful dashboard.

We're excited to share that the team behind CelerX is joining forces with Avara to accelerate our mission of bringing embedded finance to every product team — from startups shipping their first card to platforms scaling globally.

We're excited to share a major feature addition to CelerX — Previews. Enabled by our collaboration with Blowfish, Previews offers an unprecedented level of transparency into every transaction before it leaves your platform.

Reliable webhooks are the backbone of any payments platform. We rebuilt our delivery pipeline from the ground up — at-least-once guarantees, idempotency keys, and per-endpoint backoff. Here's what changed and why it matters for your team.
