1️⃣ Who Attends (Buyers / Attendees)

This congress is highly specialized and research-driven, so “buyers” here are best interpreted as the types of organizations and roles that influence decisions around: clinical research, education and guideline development, diagnostic and therapeutic adoption, hospital/health system procurement needs (indirectly through scientific advocacy), investigator networks, translational studies, and commercial partnerships.

Primary attendee groups

• Clinician-scientists and physicians specializing in thrombosis, hemostasis, and vascular biology
• Researchers and academic investigators in coagulation biology, platelet function, anticoagulation, and vascular mechanisms
• Medical/clinical laboratory leaders who focus on diagnostic pathways and lab evaluation methods
• Academic departments and research institutes supporting trials, registries, and translational projects
• Industry representatives (industry partners) spanning therapeutics, diagnostics, medical devices, and related R&D ecosystems
• Allied health and academic education stakeholders connected to continuing education and dissemination of best practices
• Scientific community participants including members of related societies, consortiums, and research networks

Buyer-relevant decision roles we typically target

• Medical Affairs / Clinical Science leadership shaping clinical evidence strategy and educational initiatives
• Clinical Operations teams involved in trial partnerships, investigator engagement, and study execution planning
• Product / Portfolio leadership in thrombosis/hemostasis segments (where applicable)
• Diagnostic / Laboratory leadership influencing adoption, validation, and evaluation of tests (for diagnostics-focused offerings)
• Research & Innovation leadership for biomarker development, translational science, and vascular biology programs
• Regulatory and Scientific Communications teams coordinating evidence packages and dissemination
• Business development / partnership leaders seeking academic-industry collaborations

2️⃣ Where the Show is Happening + Attendee Geographic Origin

ISTH 2026 takes place in Paris, France (city and country provided by the official event website). Because the congress is explicitly described as a global convergence of experts, the attendee geographic origin is best characterized as international. The official text does not break down specific country-by-country shares, so we treat origin as global rather than “one-country-dominant.”

Geographic origin (best-fit characterization based on the official description)

• Global / international mix (explicitly supported by “world’s experts” and “global participants”)
• Strong European presence is reasonable for a Paris-hosted scientific meeting, but exact shares are not provided in the supplied text
• North America, Asia-Pacific, and other regions are also expected given the “global participants” statement

Best geographic targeting approach for outreach

• Europe-wide targeting (France + nearby countries) for strongest local relevance
• Global targeting for industry partners, medical affairs leaders, and international research stakeholders
• Cross-border targeting for multinational pharma/biotech/diagnostics organizations with global clinical programs

3️⃣ Audience Reach (Local / National / Global)

The official event description frames ISTH Congress as a premier destination and a global convergence of thrombosis and hemostasis experts. Therefore, the audience reach is best categorized as global.

• Local: Paris and France receive meaningful presence, but the event is not primarily a local trade fair.
• National: France likely contributes a significant cohort of researchers/clinicians, but the main value proposition is international.
• Global: Supported by official statements including “world’s experts,” “global participants,” and international networking objectives.

4️⃣ Sample Buyer Company Names (BUYERS ONLY) + Websites

Below are buyer-style examples appropriate for a thrombosis/hemostasis congress ecosystem. These are intended as research starting points to help us validate which companies best match your specific product and targeting needs.

Important: We will refine the final buyer list to your product fit once we review your client website (your “buyer fit” can vary heavily between therapeutics, diagnostics, devices, research tools, and education platforms).

15–20 Buyer Samples Table (For Research/Shortlisting)

Best 5 samples to shortlist first for initial qualification: Boehringer Ingelheim, Roche, Siemens Healthineers, Thermo Fisher Scientific, IQVIA. These represent a balanced mix of therapeutics/medical affairs, diagnostics, clinical science support, and data/clinical operations relevance.

5️⃣ Job Profiles, Industries & Event Type

Event type

This congress is primarily a medical and scientific conference in the fields of thrombosis, hemostasis, and vascular biology. It features extensive scientific programming, plenary sessions, and state-of-the-art research updates.

Job profiles to target (high-probability buyer roles)

• Medical Affairs Director / Medical Science Liaison (MSL) focused on thrombosis, hemostasis, hematology, or vascular biology
• Clinical Development / Clinical Science Lead for trial planning and clinical evidence strategy
• Translational Research Leadership connecting bench research to clinical application
• Diagnostics / Coagulation Testing Leadership (where diagnostics or lab tools are relevant)
• Scientific Partnerships / Business Development teams working with hospitals, academic centers, and research consortia
• Clinical Operations Leaders (CROs, trial services, or data/analytics providers)
• Regulatory & Scientific Communication leadership supporting evidence dissemination
• Research Program Directors in hematology/thrombosis-related pipelines

Suggested industry categories (aligned to the provided industry list)

Based on the congress topic and typical buyer ecosystems, the best-fit industry filters from the provided industry list would be:

• Pharmaceuticals
• Biotechnology
• Medical Devices
• Hospital & Health Care
• Research
• Medical Practice
• Information Services (for data, clinical evidence, registries—when applicable)
• Market Research (if the product category is insights/analytics related to clinical adoption)
• Professional Training & Coaching (only if the offering is education/continuing education-focused)

6️⃣ Estimated Attendance (Expected Total Footfall)

The official website states: Over 6,000 global participants. This makes ISTH 2026 a mid-to-large scale global congress.

• Estimated total attendance (expected footfall): 6,000+ global participants
• Industry partners expected: 70+ industry partners

Practical note for targeting: at scientific congresses, buyer density is often distributed across industry partner areas, medical/clinical sessions, poster sessions, and networking touchpoints. Therefore, role-based targeting (medical affairs, clinical development, diagnostics/coagulation leadership, and partnerships) generally performs better than broad attendee targeting.

7️⃣ Key Focus Areas & Buyer Engagement

The congress is built around “the latest science in thrombosis and hemostasis,” and the official page emphasizes global experts, networking, and scientific sessions. Engagement themes typically revolve around:

Key focus areas we expect at ISTH Congress

8️⃣ Client-Product Fit: Finding the Best Buyers for Your Specific Requirement

To identify the best buyers we need to map your product category to the most relevant scientific/clinical stakeholders attending ISTH Congress. We request your client website URL so we can review it and then confirm the buyer fit.

What we will do after we review your client website

• We will classify your product into the most relevant congress-aligned category (therapeutics, diagnostics, medical devices, research tools, CRO/data/analytics, or education)
• We will select the best-matching buyer roles (medical affairs, clinical development, lab/coagulation leadership, partnerships, scientific communications, etc.)
• We will shortlist the most relevant buyer companies from the congress ecosystem and align them to your product language
• We will prioritize buyers most likely to engage with a product like yours based on their typical activities and departmental focus

Quick self-check (so we can accelerate the fit once you share your URL)

• Is your offering primarily for clinicians/medical science teams, or for laboratories/diagnostics, or for research/clinical development, or for education?
• Do you address thrombosis, hemostasis, or both?
• Do you sell to hospitals/health systems, to labs, or to industry R&D/clinical trial stakeholders?

Please share your client website, and we will return the best buyer shortlist for ISTH Congress tailored to your requirements.
