The short version

  • Each has a real cost: Koa Health psychPlus acquired Koa Health in June 2026, so buyers are now contracting with the technology arm of an American psychiatry provider group rather than a European digital health company, and roadmap, data residency and European product investment should all be re-examined before renewal.; Signant Health no pricing is published, and the software licence is a minority of the real bill once instrument licensing, translations, device provisioning and services are added, so early budget estimates are routinely too low.
  • They diverge on capability: Koa Health covers Stepped care triage, Signant Health covers eCOA and ePRO.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Koa Health

  • PsychPlus acquired Koa Health in June 2026, so buyers are now contracting with the technology arm of an American psychiatry provider group rather than a European digital health company, and roadmap, data residency and European product investment should all be re-examined before renewal.
  • Stepped care only produces savings when triage is accurate, and members routed to a self guided module when they believe they need a therapist commonly disengage entirely, which a utilisation report records as low engagement rather than as a triage failure.
  • Pricing is per employee or per member per month across the eligible population, so an employer with modest engagement pays for everyone in order to serve a minority.
  • Clinician availability and language coverage differ substantially by country, so a multinational contract that reads as one global standard delivers a materially different experience in secondary markets.
  • Koa competes against much larger and better funded benefits vendors in the United States, and the acquisition does not change the fact that its brand recognition with American benefits consultants is low, which affects broker driven shortlists.

Signant Health

  • No pricing is published, and the software licence is a minority of the real bill once instrument licensing, translations, device provisioning and services are added, so early budget estimates are routinely too low.
  • Linguistic validation is charged per instrument per language and is on the critical path to first patient in, so adding a country late in start-up produces both a cost and a schedule hit.
  • Provisioned participant devices bring logistics, replacement, shipping and cellular connectivity obligations that persist for the life of the trial and are frequently underestimated.
  • The EDC component is newer than the eCOA heritage, so sponsors with complex data management requirements often keep an incumbent EDC and lose the single-database benefit that justifies the platform.
  • It is priced and scoped for sponsor-grade trials, which makes it a poor fit for investigator-initiated or academic studies that need outcome collection without the services layer.

Signant Health: What is Signant best at?

Electronic clinical outcome assessment, particularly rated scales in central nervous system and psychiatry trials, together with rater training and endpoint quality services.

Koa Health: Who buys Koa Health?

Employers, health plans and health systems. It is not sold direct to individuals.

Signant Health: Is pricing published?

No. Everything is quoted per study, and instrument licences, translations and devices sit on top of the platform cost.

Per employee or per member per month, quoted rather than published, with the rate depending on which steps of the care ladder are in scope.

Signant Health: Can I use it only for eCOA?

Yes. The modules are selected per protocol, and many sponsors take eCOA and eConsent while keeping an existing EDC.

Koa Health: Does it provide access to psychiatrists?

Clinical access is included in the higher tiers, and the PsychPlus acquisition adds psychiatry provider capacity in the United States. Confirm what your specific contract covers.

Signant Health: What drives the timeline?

Translation and linguistic validation of outcome instruments, which is per language per instrument and sits on the critical path to study start.
