Marisa.Care

Marisa.Care, based in Belo Horizonte, Brazil, sells AI agents to hospitals, clinics, health plans and laboratories in Latin America. A call center agent answers patients 24/7 by voice and WhatsApp in natural language and books, cancels and reschedules against the institution's real schedule, handing sensitive cases to the human team. A concierge agent reads the record for prescribed exams and consultations never booked and offers scheduling over WhatsApp, confirms appointments with preparation guidance, rescues no shows and runs digital check in. A clinical support agent transcribes consultations and drafts structured notes, certificates and referrals. The company was founded by physician João Vitor Innecco Arêas, its chief executive and named technical lead.

Its Data Protection Notice, written under Brazil's LGPD, makes the partner institution the controller of patient data and Marisa.Care the operator, and grants a right to request review of decisions made solely by automated processing. The site says the company does not provide medical services. Outcome figures are published as ranges without a named customer, and no price, security attestation, model provider, hosting location or handoff criteria are published. Ask for the handoff rules for urgent calls, and which models and cloud providers receive patient conversations.

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

AI Capability
AA on AI CentralityThe artificial intelligence is the product. Remove the model and there is nothing left to sell.
Vendor Published

The agents are the product. Marisa.Care sells three AI agents to health institutions: a call center agent that answers patients by voice and WhatsApp in natural language, 24/7, and books, cancels and reschedules against the real schedule with no menu; a concierge agent that finds prescribed exams and consultations never booked, confirms appointments, rescues no shows and runs digital check in; and a clinical support agent that transcribes consultations and drafts structured notes, certificates and referrals. The conversations, the transcription and the drafting are done by the models, and the integration layer exists to feed them. Remove the models and there is nothing left to sell.

CC on Autonomy and Oversight ModelAutonomy is claimed and oversight is asserted without a mechanism. Human in the loop appears as a phrase rather than a described control.
Vendor Published

The agent is always on and the handoff is a phrase. The call center agent answers patients 24/7 by voice and WhatsApp and books, cancels and reschedules without human intervention; the home page says it transfers to the human team with the conversation's context when the case requires, directs sensitive cases to the human team automatically, and prioritizes patients by mapped health risk. The concierge agent contacts patients unprompted about pending exams from the record.

No criterion is published for what counts as sensitive, what a patient describing an urgent symptom hears, the hours of human cover, or how risk prioritization is set; the Data Protection Notice leaves validation and supervision to each institution.

CC on Model and Technology TransparencyThe architecture is described in general terms with nothing identified. Proprietary is asserted rather than explained.
Vendor Published

The architecture is described in general terms with nothing identified. The home page says the agents are orchestrated by the company's own infrastructure, which centralizes and interoperates data and integrations, and that the call center agent works in natural language by voice and text. No speech recognition or language model, version or update practice is named, and no evaluation method is published.

CC on Model Supply Chain DisclosureThe architecture is described and no model provider is named. Naming a hosting provider alone does not lift a record out of this band. Record the host in the note, because it matters for residency and breach scope, and grade on the model layer, which is the question this axis is named for.
Vendor Published

The architecture is described and no model provider is named. The home page describes the company's own orchestration infrastructure, and WhatsApp is named as a patient channel, which places a messaging platform operator in the chain. The Data Protection Notice says data may be shared with service providers and suppliers and processed abroad through cloud services, without naming any of them. No subprocessor list, host, speech recognition provider or language model provider is named.

CC on Clinical and Operational EvidenceNamed customers, or vendor reported percentages with no method, denominator or reference standard. Scale of use is recorded here and is not treated as evidence of benefit.
Vendor Published

Vendor reported ranges with no method. The home page reports, as ranges "based on clients with a similar profile", more than 60 percent of contacts resolved by the AI without a human handoff, a 30 to 50 percent cut in operating cost, 15 to 30 percentage points more prescribed exams converted, and a 20 to 40 percent reduction in no shows, and says each operation is projected in a commercial assessment. No customer, period, baseline or denominator is given for any figure, and no study of the agents is published.

CC on AI Safety and PHI StewardshipGeneral assurances of privacy and security that do not answer the questions artificial intelligence raises: what is retained, what reaches a model, and what happens to it there.
Vendor Published

General assurances that do not answer the AI questions. The Data Protection Notice says patient data is processed automatically, including with artificial intelligence, to carry out the service, support continuity of care, organize information, support process management and improve the quality of the service, under the partner institution's guidelines; it keeps data as long as needed for the purpose, and offers anonymization, blocking or deletion on request.

It does not say whether conversations, recordings or record content are used to train or improve the agents' models, what is retained after a call, or whether anything is de identified before it reaches a model. No safety engineering is published: no guardrails for a patient facing agent and no account of how a safety event is handled.

Regulatory and Compliance
BB on HIPAA and BAA PostureBusiness associate status is stated and supported by a substantive privacy document, with the agreement or its scope not fully published. For a vendor outside the United States, an equivalent regime documented to this depth grades here. A vendor whose product does not process protected health information grades here too when it says so plainly and explains the scope, with a service privacy document behind it: stating a position a buyer can rely on is the posture this axis grades, and the band above is closed to it because there is no agreement to publish.
Vendor Published

A non US regime documented to depth. Marisa.Care is a Brazilian company, and its Data Protection Notice (last updated 10 June 2026) states that when its solutions are used in care delivered by a partner institution, the hospital, clinic, health plan or laboratory is the controller of the patient's data and Marisa.Care acts as operator, processing on the institution's instructions within its contract.

The notice is written under the LGPD, names the data protection officer's channel (encarregado@marisa.care), sets out data subject rights and commits to report security incidents to data subjects and the ANPD. The company does not invoke the United States rule, and business associate terms for United States customers are left unaddressed.

DD on Security Certifications and Trust CenterControls are asserted with nothing independent behind them, or nothing is published. Read the note before concluding anything: this is the grade most often corrected on a second pass, because assurance material frequently sits on a parent domain or inside an old announcement rather than on the product pages.
Vendor Published

Controls are asserted with nothing independent behind them. The home page describes a robust infrastructure aligned with regulatory standards, and the Data Protection Notice commits to technical and organizational measures and to notifying data subjects and the ANPD of relevant security incidents. No ISO/IEC 27001, SOC 2 or other independent attestation, penetration testing statement or trust page is published.

CC on FDA and Regulatory StatusNo device claim is made and the product is scoped accordingly. Most administrative and operational products sit here and are not penalized for it, because this axis grades the appropriateness of the positioning rather than possession of a clearance.
Vendor Published

A scope statement sits beside clinical support. The site footer and the Data Protection Notice say Marisa.Care does not provide medical services or clinical care and that its solutions are technological and operational, supporting institutions' process management, and name a physician as technical lead. The clinical support agent is marketed as offering evidence based decision support during the consultation, and the call center agent prioritizes patients by mapped health risk.

The same agent directs "sensitive cases" to the human team automatically, and nothing published says what counts as sensitive or who decides. No registration or position under ANVISA, the Brazilian device regulator, or any other regime is published. A responsibility statement beside clinician facing support is tension rather than a stated regulatory position.

CC on AI Governance and Bias DisclosureResponsible artificial intelligence is committed to in policy language with no evaluation behind it. Most of the index sits here.
Vendor Published

Governance is committed to in policy language with no evaluation behind it. The Data Protection Notice describes a data protection governance program and says the solutions follow validation and supervision flows set by each institution, and it grants a right to request review of decisions made solely by automated processing, with transparency limited by trade secrets.

No evaluation of the agents is published, including how well the voice agent understands callers across accents, age groups and speech patterns, or how the risk prioritization performs for different patient groups.

CC on AI Liability and RecourseMechanisms exist that let someone challenge an output, such as audit trails, source traceability or review before commit, with nothing standing behind the output and no route for the harmed party.
Vendor Published

Mechanisms exist, and the recourse route runs through the institution. The call center agent hands conversations to the human team with context, and the Data Protection Notice says the solutions follow validation and supervision flows each institution defines.

The notice grants a right to request review of decisions made solely by automated processing, with transparency limited by trade secrets; because Marisa.Care acts as operator for patient data, with the institution as controller, that right runs to the institution rather than being answered by Marisa.Care. No error rate, warranty or remediation commitment for a wrong booking, a missed urgent call or a wrong drafted note is published.

Integration and Deployment
CC on EHR and Interoperability DepthIntegration is claimed through standards or a middleware layer with no system named and nothing to verify.
Vendor Published

Integration is claimed with no system named. The home page describes native integration with the main hospital information systems on the market and says the agents operate connected to the medical record, the schedule and the institution's systems, reading prescribed exams from the record and booking against the live schedule. No record system, hospital information system, standard or deployment is named.

CC on Deployment Model and Data ResidencyA single hosted option with location implied rather than committed.
Vendor Published

A single hosted service with its location left open. The agents run as Marisa.Care's hosted service over voice and WhatsApp. The Data Protection Notice says data may be transferred to, stored in, processed in or accessed from other countries through cloud computing, support, communication and security services, under LGPD safeguards such as standard contractual clauses; no provider, region or country is named, and tenancy is not described. WhatsApp as the patient channel adds a messaging platform operator to the processing chain.

Commercial
CC on Commercial TransparencyNo price is published and the posture is discoverable: a buyer can establish how the product is sold and what drives the cost before contacting the vendor. Most of the index sits here.
Vendor Published

No price is published, and the posture is discoverable. Marisa.Care sells to hospitals, clinics, health plans and laboratories, and the route in is a meeting booked through the site, where a commercial assessment projects results for the buyer's operation. The home page frames value as cost reduction and revenue recovered from converted pending exams and filled no show slots. No price, unit of charge or contract shape is published.

CC on Setting and Specialty CoverageCoverage is claimed broadly without specifics, or stated clearly with nothing validating it yet.
Vendor Published

Coverage is stated clearly with nothing validating it yet. The agents are sold to hospitals, clinics, health plans and laboratories in Latin America for call center, patient access, follow up and consultation documentation, with WhatsApp and voice as the channels. The outcome ranges on the home page are vendor projections without a named customer or method, so no part of that coverage carries published validation.

Two things to settle. The unit of charge, whether per agent, per contact, per conversation or per converted exam. And, if any fee is tied to bookings, what limits apply to unsolicited outreach to patients.
