Other published head to head assessments involving these vendors or their closest peers.
Both records were reviewed on this site in September 2026. Neither publishes a price. Assort's triage page promises "no misroutes" and that "every caller reaches the right team, every time". A handoff shows staff the calls the agent sent up, not the ones it kept, so the promise cannot be checked. Assort's agents sort callers by urgency, and it states no regulatory position for that. Assort's business associate agreement lets it de identify patient data and use it commercially after the contract ends. Marisa.Care prioritizes callers by mapped health risk and hands "sensitive cases" to staff, with no rule for what counts as sensitive. It says it provides no medical services, and it publishes no registration with ANVISA, Brazil's device regulator. Marisa.Care's outcome figures are ranges with no named customer or method. Assort names a SOC 2 Type II attestation, and Marisa.Care names none. Neither names its hosting provider or subprocessors.
Ask Assort for its misroute rate from production, and ask Marisa.Care what triggers a handoff and who sets it.
