ThetaRho
ThetaRho sells a clinical intelligence platform in three layers and will sell any of them on its own. The data integration layer parses documents, matches and de-duplicates patients, and converts data from EHRs (athenahealth and Epic named), health exchanges reached through CommonWell and TEFCA, wearables and apps, and research sources such as PubMed into FHIR R4, annotated with RxNorm, LOINC, SNOMED CT, ICD-10 and MeSH. The AI layer adds BioClinical BERT semantic search, clinical natural language processing, and question answering on Aloe and Gemma or Qwen models, grounded in the patient record with citations. The stack can be delivered as a stand-alone appliance inside the customer's security perimeter or reached through APIs.
The company's own application is RISA, built for athenaOne and listed on the athenahealth Marketplace since October 2025. A physician asks in plain language for notes, labs, imaging or outside records; RISA retrieves them from the chart and connected exchanges, applies published guidance to the patient in front of them, writes pre-visit and since-last-visit summaries, and drafts notes, referral summaries, prior authorization justifications and billing recommendations. A grounding engine marks each medical concept green when it traces to the patient record and orange when it does not. The company lists chart review, documentation and patient-specific research as live, orders and referrals as next, and decision support as future, with every action queued for physician approval.
The other buyers are builders: health information exchanges, integration, population health and analytics platforms, public health agencies, clinical AI startups, decision support and payer technology vendors, EHR vendors and life sciences companies that want normalized, annotated data without building the pipeline themselves. Ask which layer is being priced, where hosted processing runs, and for the privacy policy, since the site's link to it returns an error.
Capability Axes
An AI Health Index grade measures what a buyer can verify from public sources on the date shown. It is not a rating of how good the product is. A vendor can build an excellent system and grade low on an axis because it publishes nothing an outsider can check. How grades read
The models drive the applications, and the platform sells a data layer that stands without them. ThetaRho's AI layer adds BioClinical BERT semantic search, clinical NLP, ontology annotation and language model question answering to normalized FHIR data, and its RISA application for athenaOne is built on that layer.
The data integration layer, which parses documents, de-duplicates patients and converts EHR, exchange and device data into FHIR R4, is sold on its own to exchanges, integration platforms, analytics companies and public health agencies. Remove the models and the normalization business remains.
An absolute claim in the marketing cuts against the product's own controls. The platform page describes clinical question answering as grounded in patient data with traceable citations and ends: "Nothing is hallucinated." The product page describes the controls that make that claim unnecessary and contradict it: a grounding engine marks each medical concept green when it traces to the patient record and orange when it cannot be traced and needs validation, and agentic actions (orders, referrals, prior authorization justifications, billing recommendations) are queued for physician review and approval before anything is finalized. A clinician who believes nothing is hallucinated will not check the orange items.
The models are named without version or evaluation. The platform page names BioClinical BERT for semantic search and Aloe and Gemma or Qwen models for clinical question answering, describes ontology annotation with RxNorm, SNOMED CT, LOINC and MeSH, and a grounding engine that marks untraceable concepts; the roadmap lists live and upcoming applications. No model version, training or fine-tuning data, update practice or evaluation is published.
A short, largely named chain. The models are open families (Aloe, Gemma or Qwen, BioClinical BERT) that can run on the customer's own appliance, and the data partners are named: CommonWell, TEFCA and ELLKAY, with athenahealth as the application host. For the hosted API no hosting provider or subprocessor list is published, and nothing states retention or consent terms for wearable and device data.
Named users and vendor figures with no method. Two physicians, Subroto Bhattacharya and Brett Swenson (also a clinical advisor), are quoted on the home page; the company says RISA is live at multiple clinics and on the athenahealth Marketplace since October 2025, saves up to five minutes per visit and returns more than two hours a day. None of these figures carries a method, and no clinic is named. Academic collaborations are listed without published results.
General assurances. The company says HIPAA and SOC 2 compliance, full audit trails and a privacy-first architecture are its foundation, and offers the platform as a stand-alone appliance inside the customer's security perimeter. The privacy policy link in the site footer returns a 404, and nothing states retention, training use or de-identification for records the hosted API processes, or for wearable and device data it ingests. No safety engineering is published beyond grounding markers.
Compliance is claimed without the document behind it. The about and product pages claim HIPAA compliance; no business associate status or agreement terms are published, and the footer's privacy policy link is broken. Third parties are invited to build on the data and AI layers, and nothing says who signs the business associate agreement when a clinician uses another company's product on ThetaRho.
A recognized certification is claimed as the company's own without the artifact. The about and product pages claim SOC 2 compliance, with the type, period and scope unstated, and no trust center or report request path is published; the platform describes audit trails and data lineage.
No device claim is made and no regulatory position is published, beside functions that press on one. FDA's 510(k) database lists no clearance for the company. RISA's live research feature answers questions such as the recommended insulin dosage for a patient by applying published guidelines to the patient's weight, A1C and medications, and the product page shows order preparation with drug interaction and renal dose checks, listed on the roadmap. Cited sources and grounding markers support a clinician's review of the basis.
Commitment without evaluation. The company names the models it runs, says it joined the Coalition for Health AI to engage early with trustworthy AI standards, and lists research collaborators (University of Pittsburgh Medical Center, University of Trento, University at Buffalo). No evaluation of RISA's answers, by patient group or otherwise, is published, and the about page's Compliance section still carries placeholder text.
Mechanisms exist and nothing stands behind the output. Answers cite their sources in the patient record and in the literature, the grounding engine flags concepts it cannot trace, and agentic actions wait for physician approval; the platform keeps an audit trail and data lineage. No error rate, omission measure, warranty, indemnity or remediation commitment is published.
Named systems with a marketplace listing claimed. RISA runs inside athenaOne, and the company says it has been live on the athenahealth Marketplace since October 2025 as a certified application; the data layer connects to EHRs through FHIR APIs (Epic named), to CommonWell and TEFCA, and uses ELLKAY's interoperability framework, normalizing to FHIR R4 with RxNorm, LOINC, SNOMED CT and ICD-10. Note drafting is live and order preparation in athenaOne is on the roadmap; how drafted content is written back is not described, and no practice is named.
Options are stated, and residency for the hosted route is not. The home page offers the Clinical Intelligence System as a stand-alone AI appliance deployable inside the customer's security perimeter, and the platform is also reached through APIs and RISA inside athenaOne. The appliance keeps processing with the customer; for hosted use no provider, region or residency commitment is published.
No price is published, and the sales route is discoverable. RISA is sold to athenaOne practices through the athenahealth Marketplace, and the data and AI layers are sold to exchanges, integration platforms, analytics companies and AI builders, with an on-premise appliance option. No unit of charge or tier is published.
Coverage is stated with nothing validating it. RISA is built for athenaOne practices, and the platform is sold to exchanges, integration and analytics platforms, public health agencies, clinical AI startups and life sciences. No specialty, age or setting limits are stated, and no evaluation in any setting is published.

Scope comes first. Three different things are sold under one name: RISA for athenaOne practices, API access to the data and AI layers for builders, and the whole stack as an appliance inside your perimeter. Each carries different cost, integration work and lock in, so a proposal that does not say which one is priced cannot be compared.
Then ask three more things. Whether RISA can be bought through the athenahealth Marketplace and on what terms. Whether exchange connectivity through CommonWell and TEFCA, and device or app data ingestion, are priced apart from the core platform. And what happens to the normalized, annotated record if the relationship ends, since portability of that asset is worth writing into the contract.
