Adjudication built for where you're headed, not what your systems allow
The market doesn't slow down for legacy infrastructure, and neither do your competitors. OneArk® is a standalone SaaS platform built for health plans and PBMs that need to keep pace, under your brand, configured around your business.
Legacy infrastructure wasn't built for where you're going
Slow configuration. A vendor roadmap you don't control. Whether you're a health plan trying to bring adjudication in-house or a PBM outgrowing the system you started on, the constraint is the same: the technology decides what's possible, not the business.
OneArk® gives you a different path.
What stays yours. What gets easier.
The relationship stays yours
Every client call, every plan conversation, still runs through you, not a vendor.
Custom plans without custom code
Build the benefit design your members need, not the one your platform allows.
Scale without rebuilding anything
Grow your book, or bring pharmacy in-house, without touching your infrastructure.
Bring your own partners
Specialty, rebate, network, and clinical vendors integrate on your terms.
Control utilization, not just price
OneArk® catches what discounts don't, in real time, before it becomes spend.
Your model. Powered by OneArk®.
Use the partners, programs, networks, and strategies that already fit your business, whether you're running a PBM or managing pharmacy benefits directly as a plan. OneArk® gives you the configurable core to run them, all under your own brand.
Real-time adjudication. Configurable logic. Faster implementation.
Every piece of OneArk® exists to remove a specific bottleneck, whether that's a benefit change stuck behind a vendor's release schedule, a plan design your current system can't support, or an implementation timeline measured in quarters instead of weeks.
