Adentris
An AI compliance copilot that reads hospital and clinic EHRs the way a trained reviewer would, looking for documentation gaps before they turn into denied claims. Founded in 2025, it has one named production customer, a reported pre-seed round, and no filing yet on the SEC's public record.
An agent that reads the screen instead of the API
Adentris sells software that watches a hospital's EHR the way a reviewer would, without touching the vendor's API. It calls this its AI Web Agent layer: logging into the record system through the same browser interface a nurse or coder uses, reading every field and signature block, and flagging what is missing, wrong, or inconsistent with what a payer requires.
The pitch is that this sidesteps what has slowed automated chart review before: EHRs do not reliably expose compliance data through their APIs, and an integration project approved by hospital IT can take six months to a year. Reading the screen instead, the company says, lets it go live on any EHR without waiting on anyone's roadmap.
The platform now spans five modules: Documentation QA, Coding QA, Prior Authorization, Appeals and Denials, and Discharge Summary generation. Each can run standalone or chained, and staff are notified by email or text, rather than a new dashboard login.
The problem: claims denied for what the chart does not say
The company's framing is that 250 million insurance claims are denied each year in the United States for documentation errors, at a cost of tens of billions of dollars. A missed medication time or a discharge note never filed: insurers run machine learning against incoming claims looking for these gaps, and providers often do not find out until the denial letter arrives, weeks later.
Adentris's answer is to move the check to the moment the chart is written, not a retrospective audit later. The company says Documentation QA moved pre-submission accuracy at one customer from 73 to 96 percent, and Appeals and Denials cut claim denials 62 percent in 90 days at another. Those figures come from the company's own materials, unaudited.
Three founders, two of them on a second run through Y Combinator
Karpov and Yudovskiy are both repeat YC founders. Karpov led AI at ManyChat, described as over $140 million in ARR, and before that founded Skipp, which he says reached $7 million in ARR on $2.8 million raised, and built Lingualeo, credited with over 20 million users. Yudovskiy was CEO of ElectroNeek, a robotic process automation company that went through YC's Winter 2020 batch, scaled to roughly $5 million in ARR across 30 plus countries per his own bio and a matching aggregator profile.
Yudovskiy frames the mission in personal terms. “I come from a family of physicians, so I watched the paperwork win long before I wrote software. Our customers have next quarter, not an eighteen-month integration. That deadline is the best product manager I ever had,” he says on the company's about page.
The third founder, Alex Odin, is credited as architect of the multi-agent system. “APIs were never coming to save the mid-market. So we built agents that read the screen the way a trained reviewer does. The integration problem did not get solved. It disappeared,” he says on the same page. Aggregator profiles list Odin as co-founder and CTO of a company called WorkDone, matching Adentris's own account that it originally operated under the name WorkDone Health before rebranding.
From behavioral health to a broader platform
Adentris built its first customer relationship in substance use disorder treatment, a corner of healthcare with dense documentation requirements. In a May 2026 press release, the company said its compliance engine had gone fully live at Sobrius, a multi-location Virginia SUD provider, covering more than 100 patients across two levels of care in under 60 days. Sobrius CEO Nelson Smith is quoted by name, and Adentris's customer page lists Sobrius and Resilient Recovery Treatment as its only named production accounts without a reference call.
The same week, Adentris announced it had expanded from a single compliance tool into the five-module platform described above, positioning itself for specialties beyond behavioral health, with Texas named as its next growth market.
What is proven, and what is still claimed
| Evidence | What the record shows | Source type |
|---|---|---|
| Y Combinator batch | Listed on YC's site as Spring 2025 (X25), founded 2025, partner Tom Blomfield. A later release calls it “Y Combinator P25,” a label that does not match YC's listing. | Accelerator record |
| Named customer: Sobrius Health | Virginia SUD provider, ASAM Levels 2.5 and 3.5, named CEO quoted in a press release describing a live deployment covering more than 100 patients. Sobrius Health is an operating company with its own public site. | Company-stated |
| Named customer: Resilient Recovery Treatment | Listed on Adentris's own customer page with a named COO, Rebecca L. No independent coverage found. | Company-stated |
| SOC 2 and HIPAA claims | The company calls its platform “SOC 2 Type I and II complete, HIPAA aligned, 42 CFR Part 2 ready.” No SOC 2 report was found published outside the company's own materials. | Company-stated |
| SEC Form D | A search of SEC EDGAR's full text search and company search for Adentris, Adentris Inc, WorkDone, WorkDone Health, and the founders' names returned no filings of any kind as of Sep 24, 2026. | Not found |
| Total funding raised | The company's blog reports a $1.8 million pre-seed round closed in April 2025. Tracxn estimates about $4 million over two rounds. PitchBook puts total funding at $2.3 million. The figures disagree with each other and with the absence of any SEC filing. | Differs across sources |
| Headquarters | The website and YC profile list San Francisco, CA. PitchBook and Tracxn both list a Reno, NV corporate address, and two May 2026 press releases carry a Reno, NV dateline. | Differs across sources |
| Employee count | YC lists a team size of 5. An Austin startup directory shows 21 on one line and cites a YC snippet of 4 on another. PitchBook and Tracxn both list 20 as of late 2026. | Differs across sources |
| Revenue reported | The company's April 2025 YC launch post cites $54,000 in ARR since the start of the batch. A separate YC founder bio cites $55,000 ARR from 3 clinics with $500,000 in ARR pilots in progress. No audited figure exists. | Company-stated |
Read plainly, Adentris has a real, named customer in behavioral health and founders with independently verifiable prior companies, but almost everything about its size and money comes from itself or from aggregators that disagree with each other, with no SEC filing to check any of it against.
What to watch
- Whether Adentris files a Form D for the pre-seed round it says closed in April 2025, or for the Seed Preferred aggregators describe.
- Named customers outside behavioral health and SUD treatment, the specialties the company says it is expanding into next.
- Independent journalism on the company; coverage found so far traces only to the company's blog or wire-distributed press releases.
- Resolution of the San Francisco versus Reno headquarters question, and the gap between the company's employee count and the higher PitchBook and Tracxn figures.
