Top Life Science Marketing Agencies for 2026

Last Updated: November 3, 2026

By Shai Reichert, Co-Founder of XDS

The best life science marketing agency for you depends on what you sell and who buys it. A CRO selling to clinical operations leads needs a different partner than a biotech preparing for its first product launch, and both need someone different from a lab-tools company chasing scientists at the bench. This guide compares nine agencies, grouped by type, with a clear note on who each one suits.

We publish this blog, and XDS is on the list. We grouped the agencies instead of ranking them, and the pros and cons are written to help you build a shortlist, not to sell you on us. If you sell a medical device, our guide to medical device marketing agencies is the better starting point.

How we chose these life science marketing agencies

We started from the agencies life science marketers ask us about most and filtered for those with a dedicated life science practice, not a healthcare page bolted onto a general agency. Then we looked at five things:

• Scientific fluency: Can the team write for scientists and clinicians without a PhD reviewer rewriting every draft?
• Audience fit: Does the agency's experience match your buyer, whether that's a lab director, a physician, a patient or an investor?
• Review readiness: For promotional work, does the agency know how to prepare content for medical-legal review and fair balance requirements?
• Commercial measurement: Can it connect campaigns to pipeline across long sales cycles? Our guide to biotech marketing metrics covers what to ask for.
• Ownership and staffing: Who owns the agency, and who will actually work on your account?

Agency descriptions draw on each agency's own public materials and the sources linked in each section. We haven't hired these agencies, so treat our notes as a starting point for your own calls.

B2B science specialists

These agencies sell to scientists, lab managers and R&D buyers. They're strongest at demand generation and technical content for companies whose customers are other life science businesses.

Altitude Marketing: B2B lead generation for clinical research and drug development

Best for: CROs, CDMOs, IRBs and clinical research technology vendors that need a full outsourced marketing team focused on leads.

Altitude is a B2B agency based in Emmaus, Pennsylvania, founded in 2004, with a team of about 35 full-time staff. Its life science clients include WuXi AppTec's drug development and medical device practices, Firma Clinical Research and Asahi Kasei Bioprocess, and the agency serves manufacturing and technology companies as well (Altitude Marketing).

Altitude describes its model as trained marketers who understand the science, backed by outside experts for technical depth, rather than a bench of in-house PhDs.

Pros:

• Long track record with CROs, IRBs and drug development service providers
• Full-time in-house team, not a network of freelancers
• Can act as an entire marketing department for a small company

Cons:

• B2B focus makes it a weaker fit for patient-facing or HCP promotional campaigns
• The agency says it doesn't write posters or journal articles, so scientific communications need another partner

Forma Life Science Marketing: Positioning and differentiation

Best for: Established tools, diagnostics and CRO companies that need sharper positioning, or two merged companies that need one brand story.

Forma is a Raleigh, North Carolina agency built around brand strategy and differentiation, with services covering digital strategy, content, market research, trade shows and mergers and acquisitions. Its published case studies include repositioning work for Agilent and bioMérieux (Forma Life Science Marketing).

Pros:

• Strategy-first approach suits companies whose real problem is sounding like every competitor
• Dedicated M&A and internal alignment services, which few agencies offer
• Client list includes large instrument and diagnostics companies

Cons:

• Positioning-led model; confirm how much ongoing campaign execution the team can carry
• Less oriented toward pharma promotional work and patient audiences

Supreme Group (Supreme Optimization, BioStrata and Clarity Quest): SEO and paid media at scale

Best for: Research-tools, reagent and instrument companies that sell to scientists and want SEO and paid media at volume.

Supreme Optimization describes itself as an AI-native life science marketing agency with scientist-marketers on staff. It anchors Supreme Group, a private equity-backed roll-up: Trinity Hunt Partners took a majority stake in 2023, and the group has since acquired Clarity Quest Marketing, Health+Commerce, BioStrata, Curator24 and Pivot Design (PrivSource).

Pros:

• In-house PhD-level scientists understand technical product details
• Benchmarking data across many life science clients helps set performance expectations
• Broad service menu after several acquisitions

Cons:

• Several agencies joined the group in a short span, so ask which team and which legacy brand will staff your account
• Private equity ownership tends to favor packaged services; confirm how much senior strategy time is in scope

Mid-size integrated agencies

These agencies cover brand, digital and communications for companies moving from science to commercial stage. They differ most in what they're best at: product and web experience, rare disease, pharma promotion or PR.

XDS: Brand, website, CRM and analytics under one senior team

Best for: Growth-stage biotech, diagnostics and medtech companies that need brand, website, CRM and analytics built and run by one senior team.

XDS (The Experience Design Studio) is the independent, founder-led studio that publishes this blog. It combines strategy, design, engineering and marketing for healthcare and life science companies, and it's a HubSpot Gold partner with Salesforce Marketing Cloud experience on the team. Clients work with the founders directly.

Life science work includes Seer Bio, a website redesign for Freenome and work for Cytokinetics, alongside device programs for Shockwave Medical and ReCor Medical.

Pros:

• One team across brand, web, CRM and measurement, so fewer agencies to coordinate
• Founder-level attention on every account
• Strong on content structure for AI search and AEO, which matters as scientists and HCPs research through AI tools

Cons:

• Smaller team than network agencies, so large multi-market launches need careful scoping
• Not a PR or medical communications firm; publication planning and media relations need a specialist partner
• Remote-first model may need adjustment if you prefer frequent in-person workshops

CG Life: Integrated marketing for emerging biopharma

Best for: Emerging biopharma companies, particularly in rare and hard-to-treat diseases, that want brand, digital and PR from one agency.

CG Life is a Chicago-based agency founded in 2003. It formed a growth partnership with Shore Capital Partners in 2023 (Business Wire), then acquired digital agency Toolhouse and Berry & Company Public Relations in 2024, growing to about 150 people (Business Wire). Its client roster has included Illumina, Roche Diagnostics and Bio-Rad (MM+M).

Pros:

• Deep experience across biopharma, diagnostics and research tools
• Integrated PR and digital after the 2024 acquisitions
• Clear specialty in rare disease

Cons:

• Recent acquisitions mean you should ask which legacy team will run your account
• Recent positioning centers on rare-disease biopharma, so tools companies should check the current roster

Calcium+Company: Promotional and medical communications for pharma brands

Best for: Pharma and biotech brands that need promotional marketing and HCP medical education from one group.

Calcium+Company is a mid-sized healthcare marketing group founded in 2012 and backed by NexPhase Capital. In 2023 it acquired CSG Health Group, a scientific communications agency focused on HCP education (MM+M), and it has since added PR and market access divisions.

Pros:

• Promotional and medical communications under one roof
• Specialist divisions, including oncology-focused work
• Mid-size scale with blue-chip pharma experience

Cons:

• Pharma brand focus makes it a weaker fit for B2B tools and CRO demand generation
• Multiple divisions; confirm which one leads your work

Spectrum Science: Science-led communications and trial recruitment

Best for: Biotech and pharma companies whose priority is earned media, scientific communications or clinical trial recruitment.

Spectrum Science is an independent agency based in Washington, DC, offering integrated communications, clinical trial recruitment and retention, advertising and consulting. It acquired SONIC Health in 2022 (Spectrum Science), and scientific communications made up about half of its business in 2023 (PharmaLive).

Pros:

• Strong PR and scientific communications heritage
• Clinical trial recruitment capability, which few agencies on this list offer
• Independent, with a global network of partner agencies

Cons:

• Communications-led, so web, CRM and performance marketing may need another partner
• Less focused on B2B tools and services companies

Large agencies and networks

Choose from this group when you have an enterprise budget and a launch that needs scale across markets and audiences.

Klick Health: Creative and medical strategy at scale

Best for: Major pharma and biotech launches that need top-tier creative, medical strategy and market access support.

Klick is a Toronto-based independent agency founded in 1997 that serves pharma, biotech and life science brands. In 2026 it was named Cannes Lions' Healthcare Agency of the Year, and it has since acquired scientific communications firm Oxford PharmaGenesis (Advertising Week).

Pros:

• Among the most awarded creative teams in health
• Scientific-to-commercial capabilities after the Oxford PharmaGenesis deal
• Independent ownership at network scale

Cons:

• Premium pricing and scale suit large brands more than early-stage companies
• Pharma brand focus; B2B tools and services companies are better served by specialists

Real Chemistry: Analytics-led healthcare network

Best for: Global commercialization programs that need data-driven targeting and in-house scientific expertise.

Real Chemistry is a healthcare commercialization network with analytics at the center. It employs PhDs, MDs and PharmDs across therapeutic areas and has worked with a large share of the top pharma brands by revenue.

Pros:

• Data and audience intelligence available across client work
• In-house scientific expertise across therapeutic areas
• Global footprint for multi-market launches

Cons:

• Network scale can mean variable team quality between engagements
• Premium positioning may not fit smaller biotech budgets

Comparison table: Life science marketing agencies for 2026

What should you look for in a life science marketing agency?

Start with your buyer, not the agency's capabilities list. A tools company selling to lab directors needs content that survives scrutiny from scientists and a lead engine that runs for quarters. A therapeutics company approaching launch needs HCP and patient work that clears medical-legal review, which is a different skill. If you're unsure where your audience balance sits, our breakdown of HCP vs. patient marketing helps.

Next, look at measurement. Life science sales cycles often run a year or more, so last-click reporting will undercount most of what marketing does. Ask every agency to show you the dashboard you'd get and how it ties campaigns to CRM stages. If your current program isn't moving pipeline, our guide to fixing underperforming biotech marketing is a useful diagnostic.

Finally, ask about ownership. Private equity roll-ups are common in this category, and the team that pitches you isn't always the team that runs your account. That's not a reason to rule an agency out. It's a reason to meet the people who'll do the work before you sign.

Should you hire a specialist or a full-service agency?

It depends on where your gaps are. Many life science companies pair a specialist for scientific content or PR with a full-service partner for the website, CRM and campaigns. That works if one partner owns measurement, so you aren't reconciling two sets of reports. If you have a lean team and no one to coordinate agencies, one integrated partner is usually simpler. Our guide to choosing a healthcare marketing agency walks through the decision in more detail.

Where XDS fits, and where it doesn't

XDS fits growth-stage biotech, diagnostics and medtech companies that need their brand, website, CRM and analytics working as one system, with senior people doing the work. That's especially true if you're on HubSpot or Salesforce Marketing Cloud, or if you want your content structured for AI search.

Other agencies on this list are a better fit in a few cases:

• CROs and CDMOs that need an outsourced B2B lead engine: Altitude Marketing is built for that.
• Earned media, scientific communications or trial recruitment: Spectrum Science leads with those.
• Large pharma launches across many markets: Klick Health or Real Chemistry bring the scale.
• Rare-disease biopharma that wants PR and brand in one agency: CG Life specializes there.

If you're weighing XDS against any of these, get in touch and we'll give you a straight answer on fit.

FAQs about life science marketing agencies

What does a life science marketing agency do?

A life science marketing agency helps biotech, pharma, diagnostics, research-tools and CRO companies reach scientific, clinical and commercial audiences. Services usually include brand strategy, scientific content, websites, digital advertising, CRM and analytics, and some agencies add PR or medical communications.

How is biotech marketing different from life science tools marketing?

Tools marketing is mostly B2B: you sell to scientists and lab buyers through long, research-heavy cycles. Biotech and pharma marketing often adds HCP and patient audiences, which brings FDA promotional rules and medical-legal review into every asset.

How much does a life science marketing agency cost?

Costs vary widely with scope and agency size. Specialist and mid-size agencies are typically engaged on project fees or monthly retainers, while network agencies price for enterprise programs. Ask for a scoped estimate tied to specific outcomes rather than a rate card.

Should a biotech hire an agency before launch?

Yes, if launch is within 12 to 18 months. Brand positioning, the website and HCP content all take time to build and clear review, and starting late usually means launching with materials you'll redo within a year.
