Top 10 HEOR (Health Economics and Outcomes Research) Consulting Firms
Spend enough time around pharma, biotech, or medtech circles and you'll hear "HEOR" come up constantly — usually in the same breath as "market access" and "payer negotiations." There's a reason for that. Getting a drug approved isn't the finish line anymore. Payers and health authorities now want hard proof that it's actually worth what you're charging for it. That's the whole job of an HEOR firm, and getting that partnership right can genuinely make or break how well your product performs once it's on the market.
What Does an HEOR Firm Actually Do?
In simple terms, health economics and outcomes research takes raw clinical trial data and translates it into the language payers and health technology assessment (HTA) bodies actually speak — things like cost-effectiveness, comparative value, and real-world quality-of-life impact. HEOR teams are the ones building the economic models, mining real-world datasets, and putting together the value dossiers that support every pricing and reimbursement discussion you'll have.
Why Pharma and Biotech Companies Rely on Them
Most companies simply don't keep this kind of expertise on staff, and the few that try often find it stretched too thin. You need health economists, epidemiologists, biostatisticians, and medical writers all working together — that's a lot of specialized hiring for a team that's already juggling approval timelines and launch prep.
The Top 10 HEOR Firms You Should Know
1. DelveInsight
DelveInsight is a healthcare-dedicated market research and consulting company with a strong HEOR and real-world evidence practice, paired with deep patient journey work. It covers nearly every therapeutic category, blending KOL perspectives, payer intelligence, and economic modeling to help pharma teams build out their strategy.
2. IQVIA
IQVIA sits at the top of the industry by sheer size, and no one else really comes close. Born out of the 2016 merger between IMS Health and Quintiles, this publicly traded company (NYSE) combines massive real-world data assets with a Real World Solutions arm built specifically for HEOR research, pharmacoepidemiology, and large-scale evidence generation.
3. Optum
Optum operates under UnitedHealth Group, which gives it something few competitors can offer — direct, built-in access to enormous U.S. claims and electronic health record datasets through Optum Life Sciences. If your evidence generation plan depends heavily on domestic payer and real-world data, this is a firm worth a close look.
4. RTI Health Solutions
RTI Health Solutions operates as the nonprofit, independently run research division of RTI International, an institute with roots going back to 1958. Its bench of more than 350 researchers, most holding PhDs or master's degrees, brings genuine academic rigor to health economic modeling and pharmacoepidemiology work.
5. Ingenious e-Brain
With over 14 years in the research and competitive intelligence business, Ingenious e-Brain has built a healthcare practice that stretches across the entire product lifecycle — from early preclinical competitor tracking all the way to post-launch commercial analytics and market access support. It's a good fit if you want a partner who understands both the science and the IP landscape surrounding your product.
6. Parexel
As one of the largest CROs in the world, Parexel doesn't treat HEOR as a standalone service — it's woven directly into its regulatory, real-world evidence, and clinical development work. The company points to more than 150 market access strategy engagements completed over the past ten years alone.
7. Analysis Group
Analysis Group approaches HEOR through the lens of economics first, which comes through clearly in its work. Its epidemiology and market access practice is built to handle complicated reimbursement scenarios for pharma, biotech, and medical device companies alike.
8. Precision AQ
Precision AQ, previously operating as Precision Value & Health, rebranded in 2024 to bring nine agencies — PrecisionHEOR among them — together under a single name. The firm is especially known for its Access Experience Team, made up of 25-plus former payer executives who understand exactly how reimbursement decisions get made.
9. Avalere Health
Avalere pairs health policy know-how with hands-on HEOR consulting, which makes it especially useful when you're dealing with complex regulatory landscapes like IRA-driven drug price negotiations. Its bench includes health economists, physicians, and pharmacists who've worked on both the payer and provider sides of healthcare.
10. Clarivate
Closing out the list is Clarivate, which leans on its Cortellis and DRG platforms to give clients access to curated pipeline data, regulatory intelligence, and real-world evidence alongside dedicated HEOR advisory support. It functions less like a traditional boutique consultancy and more like a full-scale data and intelligence engine.
How to Pick the Right HEOR Partner for Your Pipeline
Match Their Strengths to Your Stage
No single firm on this list is the right call for every scenario. Large data-driven players like IQVIA or Clarivate shine when you need scale and access to existing datasets. Smaller, more boutique firms often move quicker and hand you more senior-level attention, which can matter a lot for an earlier-stage biotech.
Early-Stage vs. Commercial-Stage Needs
Before launch, your priority is usually building the initial economic models and value narrative. After launch, the focus shifts toward generating real-world evidence that backs up the performance claims you made going in.
Ask About Therapeutic Area Depth
HEOR work isn't interchangeable across disease areas. Rare disease, oncology, and cardiometabolic conditions each bring their own data hurdles, so push any firm you're considering to show you relevant experience in your specific therapy area before signing anything.
Final Takeaway
Truthfully, there's no universal "best" HEOR firm — only the one that lines up with where your product is in its lifecycle and the kind of evidence you need to generate next. Treat this list as a launchpad for your search, not the final answer, and don't hesitate to ask tough questions before committing to a partner.
