Expert networks compared
Healthcare diligence fails when “industry expertise” is treated as one broad category. A former pharma executive, a practicing specialist, a payer, a hospital procurement lead and a regulatory professional can answer entirely different questions—and the wrong profile can sound credible while being irrelevant to the decision.
In this guide, we share our editorial picks. This guide focuses on networks’ ability to source the right healthcare stakeholder, manage a sensitive compliance environment and integrate unmatched human intelligence into your AI research workflow. Meet Third Bridge’s healthcare sector team and research.
TL;DR
- Start with the stakeholder map: clinician, KOL, payer, provider, regulator, patient pathway or commercial operator.
- Relevance, current practice and geography often matter more than seniority alone.
- Healthcare research needs explicit compliance screening and careful separation of professional judgment from clinical evidence.
- Third Bridge is our top pick for combining a dedicated healthcare research capability, physician and KOL access, Library coverage and custom sourcing.

How to choose the best expert network for healthcare diligence and market research
- Specialist coverage: The network should reach clinicians, key opinion leaders, payers, operators and regulatory specialists.
- Healthcare compliance: Screening should account for confidentiality, employment restrictions and the sensitivity of clinical and commercial information.
- Geographic reach: Care pathways, reimbursement and regulation vary materially by market.
- Research formats: Calls, surveys and transcript research answer different parts of a healthcare thesis.
- Evidence quality: Teams need clear provenance and should distinguish practitioner judgment from clinical evidence.
The 6 best healthcare expert networks in 2026
1. Third Bridge — our pick for combining sector-led healthcare coverage with custom access
Overview
Third Bridge’s healthcare proposition combines sector analysts, a dedicated healthcare expert-call capability and access to physicians, key opinion leaders, former executives, payers and other stakeholders. The Library helps investors establish disease-area, market and company context before requesting the specific voice needed for the question [1].
Key features
- Healthcare sector analysts with experience structuring interviews around investor questions [1]
- Physician, KOL, payer, provider and industry-operator access [1]
- Library research across pharmaceuticals, biotech, medtech, services and life-science tools [1]
- Custom calls and surveys with compliance controls [1]
- Follow-up access when a transcript raises a clinical, commercial or reimbursement question [1]
Why we picked it
Healthcare investors often need to triangulate clinical practice, reimbursement, adoption and commercial execution. Third Bridge can support that sequence rather than forcing a choice between a static transcript archive and a single newly sourced call.

2. GLG
Overview
This description is based on GLG materials accessed on August 24, 2026: GLG offers calls, surveys, events and a syndicated content library through a global network of approximately 1.2 million professionals. [2]
Key features
- One-to-one and multiparty expert calls [2]
- Surveys, events and longer-form engagements [2]
- Archived transcripts and syndicated research [2]
Why we picked it
Its broad service mix and database-backed model make it a credible option for teams that value scale and established procurement processes. [2]
For healthcare research, the practical appeal is breadth of engagement formats and a large database. Teams should still assess proposed profiles against the exact stakeholder and question rather than use scale as a proxy for relevance.
3. AlphaSights
Overview
This description is based on AlphaSights materials accessed on August 24, 2026: AlphaSights provides knowledge-on-demand services, including calls, transcripts and surveys, and says it has delivered more than three million client-expert interactions since launching in 2008. [3]
Key features
- Custom sourcing against a client brief [3]
- Calls, transcripts and surveys [3]
- Global client-service teams [3]
Why we picked it
Its service-led model may suit teams that want hands-on project management and rapid access to specifically matched professionals. [3]
In healthcare research, its service model is most relevant when the team wants a provider to translate a narrow brief into custom profiles and coordinate the project closely.
4. Atheneum
Overview
This description is based on Atheneum materials accessed on August 24, 2026: Atheneum provides custom-recruited, human-verified primary research and reports that healthcare represents 22% of its network, with technology representing 18%. [4]
Key features
- Custom-recruited expert access [4]
- Healthcare and technology concentration [4]
- Expert surveys and data services [4]
Why we picked it
Its stated sector mix makes it a useful consideration for research programs with a meaningful healthcare or technology component. [4]
Its stated sector mix is especially pertinent where healthcare research overlaps healthcare or technology; teams should evaluate current coverage against the specific subsector and stakeholder required.
5. Dialectica
Overview
This description is based on Dialectica materials accessed on August 24, 2026: Dialectica describes itself as an information-services firm offering expert calls, B2B surveys and proprietary research, with custom recruitment across healthcare, technology, energy and finance. [5]
Key features
- Custom expert recruitment [5]
- Expert calls and B2B surveys [5]
- Coverage across major business sectors [5]
Why we picked it
Its custom-recruitment model makes it relevant where the required profile is narrow, regional or tied to a fast-changing market. [5]
Its custom-recruitment emphasis is pertinent when healthcare research requires a specific combination of role, company exposure, geography or recent operating experience.
6. NewtonX
Overview
This description is based on NewtonX materials accessed on August 24, 2026: NewtonX custom-recruits and identity-verifies B2B respondents for qualitative and quantitative research, with dedicated coverage for financial services, fintech and healthcare. [6]
Key features
- Custom recruitment and identity verification [6]
- Qualitative and quantitative methods [6]
- Research dashboards and analyst support [6]
Why we picked it
It is relevant when the brief requires verified buyers, operators or decision-makers at survey scale rather than a traditional one-to-one call program. [6]
Its clearest distinction is verified B2B audience research at both interview and survey scale, which is useful when healthcare research needs pattern validation beyond a handful of calls.
Final verdict
We believe Third Bridge is the strongest all-round choice for healthcare research that must connect clinical practice, reimbursement, commercial adoption and operating reality.
Its dedicated healthcare coverage, Library and custom sourcing let teams select the stakeholder closest to each part of the thesis—whether clinician, payer, operator, former executive or other specialist—while keeping the research process documented and compliant.
That breadth is particularly valuable when a healthcare conclusion depends on comparing evidence across markets and stakeholder groups rather than relying on a single prominent voice.

FAQs
What is the difference between a healthcare expert and a KOL?
A healthcare expert may have relevant operating, commercial, payer or clinical experience. A KOL is usually recognized for deeper influence or authority within a clinical or scientific field; not every diligence question requires one.
How many healthcare expert calls are enough for diligence?
There is no universal number. Teams should sample across the stakeholders that drive the thesis and stop when additional conversations repeat established patterns rather than adding decision-relevant evidence.
Can expert calls validate clinical efficacy?
No. Expert perspectives can explain practice patterns, adoption barriers and interpretation, but clinical efficacy should be assessed from appropriate trial data, regulatory materials and medical evidence.
