Candid Health vs Collectly (2026)
Both improve what a practice collects, from different ends of the ledger, and they now meet at eligibility. Candid Health automates the payer side for medical groups and digital health companies, built to get claims right on submission and measured by a touchless claim rate it defines on its product page. Collectly works the patient side across the visit: check in, an eligibility and benefits agent, cost estimates, statements, payments and Billie, a billing agent. If denials and payer lag dominate your receivable, start with Candid. If the uncollected balance is increasingly owed by patients, start with Collectly.
- Built for medical groups and digital health companies, API first, rather than adapted down from a hospital platform.
- Measured on one outcome it defines publicly: the share of claims submitted, processed and adjudicated correctly the first time with no manual touch.
- Claim submission through payment as one continuous path.
- The patient's financial path in one place, from eligibility and cost estimates before the visit to statements, payment plans and a billing agent after it.
- An eligibility and benefits agent that retrieves benefits from clearinghouses and payer portals and flags prior authorization requirements.
- Scale on the patient side: more than 3,000 facilities and over $1 billion in patient revenue managed.

Each vendor in one paragraph
Written to be quoted whole. Each paragraph opens the AI Health Index profile of the vendor: what the product is, who buys it and what it does.
Revenue cycle automation platform for medical groups, managed service organizations and digital health companies, built around touchless claim rate, which Candid defines as the percentage of claims submitted and finalized without human intervention. The core is a rules engine carrying reverse engineered payer rules, kept current with payer requirements, with customer authored custom rules on top and around the clock validation and autocorrection of billing data; Candid says it uses ML and AI to automate the loop from claim insights to rule changes.

Collectly sells AI revenue cycle automation for patient financial work across the visit. Before the visit, pre-visit intake automation handles digital check-in, insurance card capture, coverage checks, demographic validation and consents. An AI eligibility and benefits agent verifies coverage, retrieves benefits from clearinghouses and payer portals, interprets copays, deductibles and carve-outs, and identifies prior authorization requirements, and AI cost estimation produces patient responsibility and good faith estimates.

Questions buyers ask
How do Candid Health and Collectly handle patient data?
Candid's privacy policy says protected health information is governed by the business associate agreements it signs with customers, not by the policy, and that Candid may share aggregated or de identified data derived from personal information to improve its services.
Collectly describes encryption, access control, audit logs and card tokenization through its processor. It also says Billie 'has been trained on hundreds of thousands of real-world patient billing questions', without saying whose conversations those were, whether they were de-identified, or whether customers' patient interactions continue to train the agent.

What evidence is published for Candid Health and Collectly?
Candid's home page names Talkiatry (manual work down 40 percent while claim volume grew), Bridge (net denials cut by more than half), Tia, Brave Health and Nourish, each with a case study.
A 2021 case study published through the athenahealth marketplace credits Collectly at CleanSlate Centers, an addiction treatment provider with 76 centers in 10 states, with patient collections up by over 250 percent, paper statements down by over 80 percent and a return on investment above 650 percent. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
How much do Candid Health and Collectly leave to the clinician?
Candid defines touchless claim rate as the percentage of claims submitted and finalized without human intervention, and places control at the rule layer: customers create custom business logic and enforce their own workflows, with training offered. The platform also validates and autocorrects billing data around the clock, and its services team steps in when a human touch is required.
In Collectly's case, the eligibility agent works autonomously 'with human review only when needed' and flags edge cases. When payer data is incomplete or ambiguous it 'applies learned reasoning patterns to infer missing details', so some copay and benefit figures shown to staff or patients may be inferred rather than returned by the payer.

Candid Health's record has not yet been reviewed on this site, so its side of this page rests on the build record. Its touchless rate is its own figure, published without a baseline.
Collectly's billing agent escalates to staff when needed and publishes no rule for when. Collections outreach that performs unevenly lands hardest on the patients least able to absorb a balance, and neither publishes results by patient group.
