ClearBill.

The United States healthcare billing system is broken — not at the margins, but at its core. Up to 80% of medical bills contain at least one error. Americans owe a combined $220 billion in medical debt. Private insurers reject roughly 1 in 7 claims on first pass. And despite federal mandates, only about 1 in 5 hospitals fully comply with price transparency rules.

The result: millions of people face financial hardship from bills they cannot understand, cannot verify, and have no practical way to dispute.

ClearBill is a patient-side billing intelligence platform built to fix this — not by plugging into broken systems, but by standing entirely outside them. It combines a personal billing liaison with AI-powered claim review, and it works directly from what patients already hold: EOBs, itemized bills, insurance cards, and correspondence. No EHR integration. No payer agreements. No institutional permission required.

The model is simple. Patients bring their bills. ClearBill reviews them, explains them, disputes errors, and resolves discrepancies — alongside the patient, not just for them. This "done with you" approach occupies a clear and largely unoccupied lane between self-service portals (opaque and impractical) and independent billing advocates (out of reach for most). It is legally clean, operationally scalable, and structurally positioned to build the largest proprietary dataset of billing-error patterns and resolution outcomes in existence.

The market for medical advocacy services is valued at $6.4 billion in 2025 and projected to reach $12.9 billion by 2032. ClearBill's MVP needs no institutional buy-in to launch, earns revenue from day one, and builds a data flywheel that becomes its long-term moat.

Billing error in America is the rule, not the exception.

Healthcare billing in the United States is structurally error-prone. Multiple payers, thousands of CPT and ICD codes, varying benefit structures, and manual data entry at every touchpoint make mistakes routine. The data is unambiguous.

The Medical Billing Advocates of America estimates that 3 of every 4 bills contain an error. A JAMA study found that of $346 billion spent on healthcare in 2018, roughly $200 billion — 58% — went to billing and insurance-related administrative activity. Billing administration alone represents about 25% of all U.S. hospital spending. And only 0.1% of denied ACA marketplace claims are ever appealed, leaving billions in erroneous denials unchallenged each year.

Behind every statistic is a patient. Receiving a medical bill is disorienting at best and financially devastating at worst. Only 20% of consumers know what they will owe before treatment. In 2022, 1 in 5 Americans reported a surprise bill despite the No Surprises Act. More than 45% of insured adults have received a bill for a service they believed was covered.

When patients do hit an error, they have almost no practical recourse. Most cannot read an EOB, spot a miscoded procedure, or know what to ask. The patients who fight back are the rare exception — not because the fight isn't worth having, but because no one is helping them have it.

Beginning in 2021, a series of federal rules created real patient rights. The Hospital Price Transparency Rule requires machine-readable standard charges. The Transparency in Coverage Rule pushed payers to disclose negotiated rates. The No Surprises Act, effective January 2022, prohibits balance billing for emergency care and out-of-network services at in-network facilities.

The problem is enforcement. As of late 2024, nearly all hospitals had posted a machine-readable file, but only about 21% were fully compliant. The No Surprises Act generated over 16,000 CMS complaints through mid-2024, resulting in just $4 million in restitution — a rounding error against the scale of the problem. A February 2025 executive order explicitly called out the failure to enforce transparency mandates. The momentum is real and accelerating, and it has opened a compliance gap that is actively harming patients.

Solace, the most prominent recent entrant, can now bill Medicare directly for advocacy — a meaningful innovation — but it still depends on Medicare eligibility and operates primarily in care navigation rather than billing dispute and resolution. The "done with you" lane, where an expert and an AI work alongside the patient to review, explain, and resolve, remains largely unoccupied.

A large market, a behavioral shift already underway, and open white space.

The global medical advocacy services market is valued at $6.42 billion in 2025 and projected to reach $12.91 billion by 2032, a 10.5% CAGR. Billing and claims assistance is the single largest segment — about 30.5% of the market in 2025 — and the U.S. leads globally at roughly 40% of share, driven by the unique complexity of the American system. For context, the U.S. medical billing outsourcing market alone is projected to reach $46.17 billion by 2033. ClearBill is not entering a small space.

Consumer sentiment is shifting fast. 74% of millennials say they would switch providers for a better billing experience. 73% of consumers say they would enroll in electronic statements, yet only 3% are enrolled today — a massive unmet demand for better digital tools. 87% want to make all healthcare payments in one place. The same shift that made patients comfortable with telehealth makes them equally open to remote billing support. The patient who will engage a ClearBill liaison already exists at scale.

This position aligns incentives completely: ClearBill wins when the patient wins. It builds trust rather than replacing the patient's judgment. It creates an ongoing relationship rather than an episodic transaction. And it generates exactly the engagement that produces ClearBill's long-term data asset.

An independent, patient-side billing intelligence layer.

ClearBill does not integrate with EHR systems, payer networks, or practice management software. It needs no institutional permission, no API agreements, and no provider buy-in. It works from what patients already have: their bills, EOBs, insurance cards, and correspondence.

This is a strategic choice as much as a structural one. By operating outside the existing billing infrastructure — as an independent advocate, not an embedded technology partner — ClearBill avoids the single highest barrier to entry in healthcare tech: institutional buy-in. It can serve patients on day one. It does not wait for an EHR vendor to approve an integration or a health system to sign a contract. The analogy is TurboTax, not Epic — with one difference: ClearBill adds a human expert who works alongside the AI.

The core operational unit is the liaison: a trained billing specialist personally assigned to each patient and their single point of contact throughout. Not a call-center agent. Not rotating. A named, responsive person who knows the case. The liaison creates trust at the moment patients are most anxious, catches edge cases the AI alone would miss, and — crucially — trains the AI with every review, determination, and dispute outcome. As the platform scales, the AI handles a growing share of routine review while liaisons focus on complex cases, insurer negotiations, and patient education.

1. Patient signs up — online or at a practice partner — and completes a Release of Information.
2. Patient receives a verification email and portal access link.
3. First login triggers the welcome workflow and liaison assignment, with notification by portal and email.
4. Patient uploads billing documents: itemized bills, EOBs, insurance correspondence.
5. Liaison reviews the submission — AI flags anomalies, liaison validates, practice or insurer outreach begins as needed.
6. Liaison reports claim status in plain language through the portal. No jargon, no waiting.
7. Patient chooses: Approve, Dispute, or Ask a Question.
8. For disputes, the liaison manages resolution with the payer or provider on the patient's behalf.
9. Ongoing support: the liaison stays available across the life of the case.
10. Insights and education: personalized recommendations and alerts for upcoming bills.

Forgoing EHR integration is not a limitation but a deliberate advantage. It eliminates the primary barrier to entry in healthcare technology — the institutional contracts, procurement cycles, and cooperation of parties who may see patient advocacy as a threat to their revenue cycle. It maintains patient primacy: ClearBill's only first-party relationship is the patient, so its incentives are never misaligned. And it produces a faster, more defensible data strategy — patient-provided documents, enriched by liaison judgment and dispute outcomes, yield a dataset that cannot be replicated by scraping EHR systems.

Narrow on purpose. Revenue from day one.

Phase 1 — B2C patient service. The MVP launches direct to consumer. No practice sign-up. No insurer agreements. No B2B sales cycle. A patient with a confusing bill can sign up today, upload documents, and have a liaison assigned within 24 hours. Real-time billing interception — sitting between provider and payer during claim submission — is not the MVP. Most errors are discoverable after the fact, from the documents patients already receive. The MVP addresses the post-submission world: achievable, valuable, and legally clean.

A freemium tier — basic bill review with limited liaison access — can serve as the acquisition funnel, with conversion to subscription or contingency as the goal.

After 12–24 months, ClearBill will have processed thousands of bills across geographies, procedures, and payer types. The anonymized, HIPAA-compliant intelligence from that dataset becomes its first B2B product, sold to regional insurers and self-insured employers: here is real-world evidence of what errors are billed, how often, by which codes, in which geographies, and here is the denial and appeal data. You cannot buy this dataset anywhere else, because it does not exist anywhere else.

With proof, data, and leverage, ClearBill opens a three-sided platform: practice-facing tools for clean claims and performance insight, insurer-facing products for preemptive fraud detection and member satisfaction, and an enhanced patient experience with proactive cost-reduction recommendations. At this stage ClearBill is not competing with EHR systems — it is a complementary intelligence layer sitting above them, connected to all three sides through a data position that took years to build and cannot be replicated.

Every case makes the next one faster, cheaper, and more accurate.

Every case generates structured data: the original bill, the codes, the identified errors, the dispute filed, the resolution achieved, the time to resolve, the payer, the procedure, and the geography. Over thousands of cases this becomes something no competitor can simply purchase or reverse-engineer — a living, validated record of how healthcare billing actually works, and fails, in the real world.

This is distinct from the claims data payers and providers hold internally. ClearBill's data is patient-side, resolution-enriched, and cross-payer. It captures what the patient was billed, what they should have been billed, what was successfully disputed, and how long it took. That combination, at scale, is extraordinarily rare — and it compounds. A billing error caught for a specific procedure, at a specific system, in a specific geography, for a specific payer, makes the next similar review faster and more accurate. Unit economics improve not despite scale but because of it.

The data also has a network dimension. Once enough patients in a geography or specialty are ClearBill users, the platform detects patterns individuals cannot: a hospital consistently overbilling a code, an insurer systematically denying a claim type, a procedure routinely miscategorized in a given state. Those pattern-level insights are valuable to regulators, self-insured employers, and state insurance commissioners — and they are ClearBill's alone.

Adjacent players. No direct occupant of the lane.

No current player occupies ClearBill's exact position: consumer-facing, technology-assisted, human-validated, outcome-aligned, and independent. The combination of AI review, a personal liaison, contingency pricing, and a data flywheel is ClearBill's. Its differentiators follow from that: independence (it works only for the patient), accessibility (subscription or contingency pricing), technology plus humanity (neither alone is sufficient), no integration required, and a data asset no competitor can acquire.

The rules are shifting in ClearBill's favor.

The Hospital Price Transparency Rule created public, machine-readable pricing that a compliant ClearBill can use to benchmark the bills its patients receive — a capability that did not exist five years ago. The No Surprises Act created enforceable rights, giving ClearBill a clear pathway when a bill violates its protections; the Good Faith Estimate requirement leaves a paper trail to use in disputes when bills substantially exceed estimates. The February 2025 executive order calling for greater enforcement and disclosure of actual prices tightens the environment further.

The honest risks, and how the model answers them.

The problem is real, lived daily by millions who deserve better.

The American billing system generates nearly $200 billion in administrative waste a year. Up to 80% of bills contain errors. Patients owe $220 billion in medical debt. And after a decade of regulatory effort, the practical experience of receiving and understanding a medical bill remains essentially unchanged for most Americans.

ClearBill enters this environment not as another vendor optimizing the provider's revenue cycle, but as the patient's own advocate — independent, accessible, and structurally aligned with the patient's financial interests. By working from documents patients already receive, forgoing institutional integration, combining AI-powered review with human expertise, and pricing on contingency or subscription, ClearBill makes professional billing advocacy available to everyone who has ever looked at a medical bill and felt powerless.

The business case is strong, the timing is right, and the tailwinds are real. ClearBill is that better.
