The Problem

Billers spend most of their time chasing denials, doing appeals, and checking claim statuses. Submission is easy — follow-up is the real problem.

This repetitive, time-consuming work overwhelms billers and creates bottlenecks. We've spoken to clinics across urgent care, pediatrics, dental, and surgery centers. They all face the same struggles:

Fragmented portals
Long hold times
Manual rework
High denial rates
Large A/R backlogs
Staff shortages
DENIED
ACTION REQUIRED

Frequently Asked Questions

We are a venture backed company, allowing us to take risks that others cannot. We will operate as a design partnership to implement AI / automation solutions in your practice. If these solutions work well, we will scale with you and give you preferential access to new software as well. By participating in this design partnership, you will be able to guide the product roadmap, ensuring what we build will work for all your practices.
Anything we build will first be tested against your staff's current workflows. If it meets an agreed-upon (ex: 95%) confidence level against your staff, we will deploy it in your practice on a trial basis.
We charge outcome-based pricing, so you will not be charged unless our software brings value to your practice. Any deposits collected will be paid back in full if we fail to deliver a working product.
