Our take

Perfect oversight on every financial transaction is beyond human capability, particularly as regulatory demands and transaction volumes continue to grow. OnCorps AI tackles this with an agentic AI platform that investigates discrepancies, recommends resolutions and learns from every exception, reducing manual labour and false positives by up to 90%.

Those capabilities have helped OnCorps with the trust of leading asset managers and fund administrators. Trained on millions of real-world financial exceptions, its AI delivers the specialist expertise needed to streamline reconciliations, reporting reviews and other operational workflows with greater speed and accuracy.

The company's momentum was also reinforced in late 2025 with a $55M growth investment from Long Ridge Equity Partners. The funding will support product innovation, business expansion and the rollout of its AI platform into adjacent capital markets workflows, putting OnCorps in a very good spot for its next phase of growth.
