Direct peers

• Infermedica: Polish health-tech company offering an AI-powered symptom-checking and triage API used by insurers and healthcare providers. Closely comparable to XUND in B2B2C model, API-first delivery, and focus on payers and digital health platforms.
• Buoy Health: US digital health company offering AI symptom checking and care navigation, sold to employers, health plans, and providers. Comparable triage and care-pathway recommendation capabilities via API and web app distribution.
• Babylon Health (eMed): AI-driven triage and virtual care platform historically serving the NHS and global insurers. Competes with XUND on symptom assessment and patient navigation, though with a stronger emphasis on full virtual primary care delivery.
• Ada Health: Berlin-based AI symptom assessment platform serving consumers directly and via enterprise partnerships with insurers and providers. Direct competitor to XUND's Symptom Check and Illness Check in coverage, languages, and target segments.
• K Health: US-based AI symptom checker integrated with telehealth and insurer partnerships. Comparable in offering AI-driven patient triage and decision support at scale, though more consumer-and-employer-led than XUND's B2B API model.
• Mediktor: Barcelona-based AI medical assistant for pre-diagnosis and triage, offered as a white-label solution to health systems, insurers, and pharma. Comparable API-first, multilingual symptom triage product targeting similar enterprise buyers.

Emerging players

• Healthy.io: Israel-based digital health company offering smartphone-based diagnostics and clinical decision support, sold to insurers and providers. Comparable MDR-grade regulated medical device positioning and enterprise GTM, but with a diagnostic-test rather than symptom-assessment core.
• Huma (formerly Your.MD): Digital health platform offering AI-powered symptom checking, remote patient monitoring, and digital biomarkers. Overlaps with XUND on AI triage and clinical decision support, with stronger RPM and clinical trial focus.
• Sensely: Conversational AI platform with an avatar for symptom assessment and chronic care management, sold to insurers and providers. Overlaps with XUND's NLP-driven patient interaction but with a more avatar-led UX.

Broad incumbents

• Doctolib: European leader in online doctor appointment booking and teleconsultation, increasingly adding patient-facing decision support. Competes with XUND on patient navigation and digital front door in DACH and France but as a much broader platform play.
