What it does

  • Patient billing platform built for medical billing companies
  • Automated statement cycles across email, text, mail, and phone
  • Built-in patient support that resolves most billing questions
  • Online payments and payment plans
  • Syncs balances with practice management systems

Where it's strong

  • The only platform in this set designed around third-party billing companies, which serve thousands of small practices the enterprise vendors ignore.
  • Proven distribution: 2,600+ practices reached through billing company partners and 3.5M+ patients have paid a bill on it.
  • Its patient support layer answers billing questions itself, reported at 90% resolution, which directly cuts billing company phone load.

What buyers should weigh

  • If you are a practice rather than a billing company, you will usually access it through a partner, which adds a layer to the relationship.
  • Its September 2025 $20M raise was structured as other equity rather than a priced Series C, worth understanding in diligence.
  • Channel focus means the patient experience can vary with how well your billing company configures it.

Raxia

AI agents that automate patient billing, payments, and support

Founded

HQ
Boston, MA
Stage
No disclosed funding
Raised
n/a

What it does

  • Automated patient billing and statement workflows
  • Rae AI agent handles patient phone and chat inquiries
  • Behavioral analytics to time and tailor outreach
  • Automated payment posting back to PM systems
  • Works across 67 practice management system integrations
  • Self-service payment plans and digital payments

Where it's strong

  • Closed loop from statement to payment to posting, including the patient support calls most tools skip.
  • Breadth of PM system connectivity suits billing companies running many client systems.
  • Behavioral analytics aim outreach at when patients actually pay, not fixed statement cycles.

What buyers should weigh

  • No named customers, disclosed funding, or founding details in public materials, so diligence falls on references.
  • Young AI-agent category; letting Rae speak to patients needs monitoring and clear escalation rules.
  • Company shares little publicly about SOC 2 status beyond HIPAA and PCI claims.
