Nexus Pay was founded in 2021 by former engineers at Stripe and Square who saw an opportunity to build payments infrastructure from scratch -- optimized for the real-time, global economy. Our platform processes transactions in 45+ currencies with instant settlement, eliminating the 2-3 day float that costs businesses billions in working capital annually.
With a single API integration, you get payment acceptance, disbursements, currency conversion, fraud detection, and compliance reporting. We handle PCI-DSS, SOC 2, and regional regulatory requirements so your engineering team can focus on building great products instead of managing payment complexity.

We migrated from our legacy payment processor to Nexus in under a week. The API documentation is the best I've seen in fintech -- our engineering team had the integration running in production within four hours. Transaction success rates improved by 8% immediately.

Nexus Pay's instant settlement transformed our cash flow. We went from waiting 3 business days for funds to having them available in seconds. For a marketplace processing $40M monthly, that's a game-changer for our float management.

The fraud detection is exceptional. We reduced chargebacks by 68% in the first quarter after switching to Nexus. The adaptive ML models catch sophisticated fraud patterns that our previous rule-based system completely missed.
