Candid Health
Billing software built to get a medical claim right before it ever leaves the clinic, now sold to more than 200 provider organizations. In July 2026 the company announced a $120 million Series D. The SEC filing behind that round reports $104.9 million sold.
The claim that comes back
A clinician sees a patient. A claim goes out to the insurer. Then the waiting starts.
Put a telehealth modifier in the wrong field, use a code this payer does not accept for this service, bill under a physician whose credentialing has not caught up, and the claim comes back. Someone works it by hand. The money arrives weeks later, or it never arrives at all.
Candid Health sells the other version of that story: get the claim right before it leaves the building. Its platform carries a rules engine tuned to the submission requirements of more than a thousand US payers, alongside machine learning models and, since 2025, AI agents that work the leftovers.
The pitch comes with numbers attached. Candid says its highest performing customers run first pass resolution and net collection rates between 95 and 99 percent. Talkiatry, a national telepsychiatry practice, is the showcase: a 98.3 percent payer net collection rate, an initial denial rate of 3.3 percent, and 40 percent less transactional work even as claim volume climbed. Every one of those figures comes from Candid. No outside auditor has published them, and the company has not said how it defines or measures a touchless claim.
Why the billing got harder
The problem is administrative, not clinical, and it is enormous. Revenue cycle management is a $280 billion industry, a figure repeated by the company, by its investors and across trade coverage of the sector. Candid puts it at more than one percent of US GDP.
There are over a thousand insurers in the United States. The claim form is standardized; what each payer wants inside each field is not. Layer on value based contracts stacked on fee for service, high deductible plans that push more of the balance onto patients, and direct employer contracts with no standard invoice format, and the billing office becomes a place where the rules live in people's heads.
Sixth Street, which led the 2026 round, cited industry surveys reporting that nearly three in four providers say denials are rising, and that more than half of denied claims are never reworked. The money is lost quietly, one unworked denial at a time.
Two Palantir engineers, and a third name
Nick Perry and Doug Proctor met at Palantir. Perry led commercial healthcare work there; Proctor built and led product and business teams serving US Special Forces and the Army. They spent five years at the company before founding Candid in 2019 with a third co-founder, Adam Reis, whose name appears in the boilerplate of every Candid release and almost nowhere else.
The founding thesis is a transplant. Billing, in their reading, is a data engineering problem of the kind Palantir was built for: unify the provider roster, fee schedules, contracts, credentialing and payer adjudication behavior into one model, and the automation follows.
Candid went through Y Combinator in the Winter 2020 batch and raised a seed round. The first product was an API. A user interface came later, then a rules engine, then queues, then a patient management system. When Fortune interviewed the founders in July 2026, Proctor turned his laptop around to show a herd of wild horses grazing behind him in upstate New York.
From API to enterprise
The customer base started with digital health companies that bill insurance: Allara, Nourish, Tia, Talkiatry. Then it moved upmarket. Candid signed its first enterprise management services organization in 2024, the same year it says revenue grew nearly 250 percent and monthly claim volume passed 650,000.
The money followed the growth, fast. A $29 million Series B led by 8VC was announced in September 2024. Five months later, a $52.5 million Series C led by Oak HC/FT. Seventeen months after that, $120 million led by Sixth Street Growth, at three times the Series C valuation, with Oak HC/FT, 8VC and Y Combinator all returning. By September 2026 the company told the Denver Post it had 250 customer organizations, 200 full time staff, and a new 14,000 square foot lease in Denver, up from 2,000 square feet.
What is proven, and what is still claimed
| Evidence | What the record shows | Source type |
|---|---|---|
| SEC Form D | Filed July 22, 2026 by Candid Group, Inc. at Candid’s San Francisco address, signed by Nick Perry as Chief Executive Officer. First sale June 3, 2026. Sold $104,873,634 from 12 investors under Rule 506(b). Directors listed: Perry, Doug Proctor, Sebastian Caliri, William Deitch, Alex Katz. CIK 0002144950. | Public record |
| Announced versus filed | The announcement says $120 million. The Form D filed the same day reports $104,873,634 sold, a gap of $15,126,366. No amendment has appeared since. | Differs from the filing |
| Security attestation | SOC 2 Type 2 examination by AssurancePoint, LLC for January 15 to April 15, 2025, covering Security, Availability and Confidentiality, with an unqualified opinion. The window is three months, not a year. The company says it intends to report annually. | Certifier |
| HITRUST certification | None found in searches on September 23, 2026. | Not found |
| Named customers | Talkiatry, Tia, Nourish and Allara appear in company materials; TechCrunch named Allara, Nourish and Talkiatry in February 2025. Elation Health lists Candid as a billing partner; Healthie documents a bidirectional integration, updated in February 2026. | Company and partner |
| Customer count | More than 100 and more than 150 both appear in the same September 2024 release. More than 200 has been the figure since February 2025. The Denver Post reported 250 in September 2026. | Company-stated |
| Performance figures | 95 to 99 percent first pass resolution and net collection rates; Nourish at a 96.7 percent touchless claim rate; about $7 billion in annual claim volume; 190 percent growth in annual contracted run rate revenue in 2025. All self reported, methods unpublished. | Company-stated |
| Claim routing | Candid's public API reference lists supported payers with Availity professional and institutional claim identifiers, which points to Availity as a route to payers. Candid does not describe itself as a clearinghouse. | Company documentation |
| Outside recognition | Best Use of Artificial Intelligence in Healthcare, 2026 MedTech Breakthrough awards, announced May 7, 2026; Fierce Healthcare Innovation Awards winner, November 2025. Both are submission based, not audits. | Independent |
| Breach history | No HIPAA breach report naming Candid Health or Candid Group found in searches of the HHS Office for Civil Rights breach portal and published coverage. | Not found |
Read plainly: the capital, the board and the security attestation are documented. The performance claims are not. Every headline number about touchless rates, collection rates and claim volume traces back to Candid or to a customer quoted in a Candid case study, and the definitions behind them are not public. That is normal for private software companies, and it is still the gap between a good story and a proven one.
What to watch
- An amended or new Form D covering the remaining $15.1 million of the announced round.
- Whether the next SOC 2 report covers a full twelve months, and whether HITRUST follows as customers get larger.
- Any third party verification of the touchless claim rate and net collection figures.
- Competition and consolidation. Adonis, Commure and Amperos raised in 2026; Ensemble and TruBridge changed hands.
In their words
“We view RCM as fundamentally a data engineering problem, and like many problems we solved at Palantir, if you solve the underlying data engineering part well, you are able to automate the end-to-end workflow to an unprecedented extent.”

“It’s much better to just submit the claim correctly the first time.”
Nick Perry, to TechCrunch, February 2025 · Interview
“In addition to a differentiated technology offering and clear proof points applying agentic AI at scale in RCM, the thing that stood out to us was Candid’s obsessive focus on customer outcomes.”
Alex Katz, managing director, Sixth Street Growth, in Fierce Healthcare, 2026 · Independent
“We went from a manual process with virtually every claim needing hands-on work to automation that submits claims efficiently and correctly.”

“Automation is the next generation of revenue cycle, and I really think Candid will be the ones to take us to the next level.”

“Plenty of opportunities exist in the Bay Area and New York. But there’s a powerful tech scene here too, with smart folks who want to solve hard problems.”
