Building a banking app, digital wallet, or trading platform?
You’ll find product teams that care about uptime, security, and audit trails. You also get a deep bench in data, energy-grade reliability, and enterprise governance.
First, US open banking moved fast in 2024, then shifted again in mid-2025. The CFPB finalized the Personal Financial Data Rights rule in October 2024. In July 2025, the Bureau said it plans to replace that rule, so program leads should keep consent, scopes, and data access modular.
Second, ACH keeps rising. Same Day ACH passed 1.2B payments in 2024, which pushes capacity planning, retries, and exception handling into the core backlog.

Final take
Houston favors builders who show their work. Pick a partner that can ship fintech app development with telemetry, controls, and payment gateway integration you can defend during exams. Run a one-week pilot on the riskiest integration, then approve the SOW once the metrics hold. Keep Itexus on top of your shortlist when you need custom builds, clean adapters, and evidence you can show to auditors.
