Ada Health
Berlin firm making a CE-marked AI symptom checker used by patients and health systems.
The call
Ada holds a regulatory badge that keeps chatbots out of hospitals for now, but shrinking headcount and traffic point toward a forced sale or down-round before that badge matters again.
Ada Health built a symptom-checker app that tells people what might be wrong before they see a real doctor. In Europe, it has official medical approval, which normally keeps out competitors. However, two big problems are squeezing it: regular people are abandoning the app for free tools like ChatGPT (visits dropped 16% in three months), and well-funded startups like K Health and Hippocratic AI are now getting the same official approvals Ada thought protected it. The company is shrinking, has not raised money in two years, and faces a make-or-break funding moment in the next few quarters. If it gets a major new investor or gets bought at a good price, the approval wall still means something. If it gets bought cheap or cannot raise money, the protection disappears.
Why
01
AI pressure: ChatGPT and Gemini as free symptom checkers, plus K Health's PatientGPT and Hippocratic AI. Free chatbots pull consumer traffic (down 16% QoQ) while K Health and Hippocratic AI chase Ada's B2B health system deals. Could AI do the core job? Only partly.
02
Bigger players: Epic Systems and health systems building in-house (Mayo Clinic, Cleveland Clinic, NHS). Hospitals increasingly build their own triage tools inside Epic's workflow instead of licensing Ada's. Could a giant copy it? Probably.
03
What protects it. EU Class IIa medical-device certification and embedded contracts that generic chatbots cannot legally replace overnight.
What would change this call
Ada announces a new funding round or acquisition in next 2-4 quarters. A priced-up round signals strength; a down-round or bridge financing signals distress.
K Health's PatientGPT expands beyond Hartford HealthCare to other US health systems. Would show Ada's B2B/regulated channel is being displaced by a funded rival.
Ada reports Q2/Q3 2026 headcount and web-traffic figures. Continued decline from current -17% YoY and -16% QoQ would confirm shrinkage toward exit.
K Health's PatientGPT expands beyond Hartford HealthCare to other US health systems. Would show Ada's B2B/regulated channel is being displaced by a funded rival.
Ada reports Q2/Q3 2026 headcount and web-traffic figures. Continued decline from current -17% YoY and -16% QoQ would confirm shrinkage toward exit.
Key numbers
- Headcount down 17% YoY to ~170
- Web traffic down 16% quarter over quarter
- Valuation stuck at $600M since Feb 2022
Named risks
- No funding round since 2023 with stale Feb 2022 valuation, raising down-round or bridge-financing risk.
- Consumer traffic eroded by general LLM chatbots, down 16% QoQ as of June 2026.
- Declining headcount, down 17% YoY as of June 2026, signaling restructuring.
- Diagnostic accuracy lead contested by newer rival Avey using 2021-22 data.
- Financial claims rely on unaudited vendor-authored figures with conflicting third-party revenue estimates.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| K Health | gaining on | Shipped PatientGPT with Hartford HealthCare as 24/7 AI care bridge, reported 2026-07-21 |
| Hippocratic AI | contesting | Filed competing clinical-AI safety-layer patent, reported 2026-04-13 |
| Avey | gaining on | Outperformed Ada on diagnostic accuracy in study using 2021-22 data |
| General LLM chatbots (ChatGPT, Gemini) | gaining on | Patients turning to chatbots first, per report dated 2026-07-21, Ada traffic down 16% QoQ |
| Health systems building in-house (Mayo, Cleveland Clinic, NHS) | gaining on | Listed as competitors by Crustdata as of 2026-06-19, reflecting in-house build trend |
| Epic Systems | contesting | Ada integrated into Epic App Orchard in 2022 but Epic controls the clinical workflow layer |
Questions people ask
- Is Ada Health profitable in 2026?
- Ada Health says it reached profitability at end of 2023 with 260% YoY revenue growth, per its own June 6, 2024 press release. This is a vendor-authored claim; independent revenue estimates from trackers like CBInsights (~$56.2M for 2024) conflict and are unaudited.
- Could ChatGPT or Gemini replace Ada Health's symptom checker?
- Ada's core symptom-triage function faces direct pressure from general LLM chatbots. A July 21, 2026 Corporate Insight report found patients increasingly turn to AI chatbots before reaching a health system's own tool, coinciding with Ada's web traffic falling 16% quarter over quarter (as of June 19, 2026).
- Is Ada Health laying off staff?
- Headcount data from Crustdata shows Ada Health fell from roughly 230 employees in November 2023 to 169-175 by June 19, 2026, a reported 17% year-over-year decline, suggesting ongoing restructuring rather than confirmed mass layoffs.
- Who is Ada Health's biggest competitor?
- K Health is a rising threat: it shipped PatientGPT with Hartford HealthCare as a 24/7 AI care bridge, reported July 21, 2026. Ada also faces Hippocratic AI's competing clinical-AI safety patent (April 13, 2026) and health systems building in-house tools.
- Who owns Ada Health?
- Ada Health is privately held and venture-backed, with no parent company. Key investors include Leaps by Bayer, Samsung Catalyst Fund, Vitruvian Partners, Access Industries, and June Fund. Its last disclosed valuation was about $600M as of the February 10, 2022 Series B extension.
- Has Ada Health raised new funding recently?
- No confirmed funding round has been publicly reported since an announced €30M raise in August 2023. CBInsights notes an unattributed, apparently minor (~$0.03M) tranche dated August 2025 of uncertain significance, as of its August 12, 2025 profile.
