Science deserves to be understood.
Biotech Marketing Agency
Twenty years ago we built webshops. Then a drug developer asked us to redesign their website — dense technical text, cryptic images, a story no outsider could follow. In the interviews, one employee finally said what the company actually does: give hope to seriously ill patients. That was the story worth telling. We’ve built for organisations like that ever since.
Marsmedia is a biotech marketing agency from Amsterdam, working for biotech companies across the US, the UK and Europe — on websites, branding and content that keep the science intact while making it easier to understand. Because innovation creates greater impact when people understand it.
For the investor who scans before the funding round, the partner who reads before the meeting, and the scientist who checks whether you actually know what you’re talking about.

Why biotech communication is different
Generic marketing breaks on biotech. Four reasons the work asks for a partner who knows the field.
Around a biotech company, everyone reads critically: the scientist checks the mechanism, the investor checks the claims, the regulator checks everything. Marketing language that would work anywhere else destroys trust here.
The craft is precision without jargon: saying what’s true, clearly, so the expert recognises the depth and the non-expert follows the story.
A biotech website isn’t a brochure — it’s due diligence material. Before a term sheet, after a publication, around a milestone: the site gets read by people deciding whether to believe you.
That changes what it has to do: credibility first, clarity throughout, and depth available for whoever wants to verify.
A discovery-stage company tells a different story than a clinical-stage one — and many biotech websites are still telling the previous phase’s story. The platform outgrew the pitch; the pipeline outgrew the page.
We build brands and websites that grow with the phase, so the communication keeps up with the science.
Biotech doesn’t do local. Your investors sit in Boston, your partners in Basel, your talent everywhere. The website has to convince all of them — in English that reads as the original, not a translation.
We work from Amsterdam for biotech companies across the US, the UK and Europe. Distance was never the constraint; understanding the field is.

Biotech marketing: what we do, specifically
Biotech website design
Websites that explain complex science without flattening it: structure for the scanning investor, depth for the reading scientist, and a story the board can retell.
Designed and built by one team, so what you approve is what goes live — with the technical foundation (speed, structure, findability) built in from day one.
Biotech branding
A biotech brand has to hold from pre-seed deck to clinical-stage website. We design identities as systems — logo, typography, colour, tone — documented in guidelines your team can actually use.
And because the same team applies the brand to the website, it doesn’t dilute in handover.
Biotech marketing strategy
Which audiences matter this phase, what does each need to believe, and which channels reach them? We build the strategy before the deliverables — so the work adds up instead of accumulating.
Grounded in twenty years of life science marketing across the wider field, and of watching what works in this sector — and what only looks like it works.
Biotech content marketing
Content that earns trust in a field where trust is the currency: publication summaries a non-scientist can follow, insight pieces that show how you think, pages that answer the questions your audience actually asks.
Written with your scientists, not around them — precision stays in, jargon stays out.
Biotech SEO
Being findable at the moment an investor, partner or candidate searches your field. Technically sound pages, content matched to real search behaviour, and the patience to build authority in a niche where rankings compound.
Measured and reported on what actually happens — positions, impressions, enquiries.
Findable in AI answers
Investors and partners increasingly ask ChatGPT, Claude and Perplexity before they ask you. We structure content so those systems can read and cite it correctly — and we measure it.

“In biotech, trust is the currency.
Marketing that flattens the science spends it.”

What working with us looks like
Picture the kickoff: four scientists at the table, explaining a mechanism. To ask the right questions, we need to already understand how a therapy moves from discovery into the pipeline, through phase 1 and 2 — and we do.
Around fifteen biotech and life science clients over twenty years taught us the vocabulary and, more importantly, when to use it.
The hardest question in this sector isn’t explaining the science — it’s articulating why yours matters when adjacent companies sound alike. That’s usually where the kickoff earns itself.
Brilliant founders, professors, researchers: experts in their field, rarely storytellers. That’s not a flaw. It’s why we exist.
The investor scans, the scientist verifies, the HCP checks the evidence. We structure story and site so each finds their layer — without flattening the science that earned your credibility.
Precision that legal and scientific review can approve, in language a first-time reader can follow.
Ninety per cent of our clients continue after the first project — some relationships run past ten years. In a sector where the story changes per phase, that continuity pays: we already know the pipeline when the next milestone lands.
“Mars had a quick understanding of our industry needs”
“With Mars, we felt supported from start to finish. Their quick understanding of our industry’s needs and proactive approach kept the project on track, ensuring both websites launched right on time.”

Working on something the world should understand? Let’s talk — we’ll keep up.
How we work
Three steps. Everyone knows what is needed, and when.
We listen, at level
The kickoff runs two to three hours, founder included — with your scientists at the table. We come in understanding pipelines, phases and platforms, so the conversation starts at the substance, not the glossary.
We find the difference
Adjacent companies in this field often sound alike. We keep asking until the real differentiator surfaces — then build the story, structure and site around exactly that.
We stay through the phases
The story changes from discovery to clinical. We stay involved as it does — 90% of our clients continue after the first project, which in this sector is the whole point.

Frequently asked questions
A biotech marketing agency helps biotech companies get understood by the people who matter: investors, partners, scientists, regulators and talent. The work spans strategy, branding, website, content and findability — with one requirement generic agencies miss: the science has to stay intact.
The test of good biotech marketing isn’t whether it sounds exciting. It’s whether the expert recognises the depth and the non-expert follows the story.
Because the failure mode is predictable: the science gets flattened into claims, the critical reader stops trusting the site, and the internal team spends months correcting copy.
A sector-specialised partner picks up the field fast enough to write with your scientists instead of around them. Twenty years in biotech and life sciences means fewer questions upfront and no trust destroyed in translation.
Work as due diligence material. Before a term sheet, around a milestone, after a publication — the website gets read by people deciding whether to believe you.
That means: credibility first (team, science, proof), clarity throughout (an investor should grasp the platform in one visit), and depth on demand (the scientist who wants to verify can).
We understand it fast — that’s the honest version. Our clients’ fields range from therapeutics to platforms to tools, and what twenty years in the sector gives us is the ability to pick up a new mechanism, pipeline or technology quickly and ask the right questions.
Your scientists stay the experts. Our job is making their precision readable.
Yes, and the work differs per stage. Early-stage: a brand and site that make the vision credible on a lean budget. Growth-stage: communication that keeps up as the story changes. Clinical-stage: the credibility layer that partners and investors expect.
What doesn’t change: we scale the deliverables to the phase, never the strategic work underneath.
An identity that holds from deck to website to conference: logo, typography, colour and tone designed as a system, documented in guidelines your team can use.
In biotech the bar is specific: the brand has to look credible to an investor and honest to a scientist at the same time. Overpromise visually and you lose the second reader.
Yes — findability is part of the work, not an add-on. Content that answers what your audiences actually search, on pages that are technically sound, with authority that compounds in a niche.
And increasingly: findability in AI answers, because investors ask ChatGPT before they ask you. We structure and measure for that explicitly.
That depends on scope, stage and the depth of the content work. Early in the conversation we share an estimate per phase, so you see what each part costs before it begins.
We’d rather help you spend the budget where it makes a difference this phase than push the most expensive version of the work.
Yes — a substantial part of our client base is in the US and the UK, alongside Europe. We work from Amsterdam through shared Slack and biweekly calls, in a process built for time zones years ago.
In practice, US clients rarely see us in person. The work doesn’t suffer for it; picking up your field quickly matters far more than sharing a postcode.
A brand identity typically runs six to ten weeks; a full brand-plus-website project ten to sixteen. Timelines are planned per phase upfront — and we plan internal decision-making in from day one, because that’s where biotech projects usually slow down.
Three things.
One: twenty years and more than three hundred websites and brands, a substantial share of them in knowledge-intensive fields like this one. We pick up your field fast, and we know which communication survives a critical reader and which doesn’t.
Two: strategy, brand, website and content in one team. No handovers where the science gets lost in translation.
Three: we build for findability in both worlds — search engines and AI answers — and we measure what actually happens.
Volume isn’t our position. Depth is.
