Summary of this blog
- Health tech startup marketing is a different job at each funding stage. At seed the job is to find the buyer and the claim the product can make. Between seed and Series A it is to prove one channel and build the proof pages. Between A and B it is to build the engine and the team, and after B it is to scale what is measured and add a fourth channel.
- The money expects pipeline on a schedule. Rock Health recorded $6.4 billion of US digital health venture funding across 245 deals in the first half of 2025, with the average deal at $26.1 million. Every one of those companies will be asked for qualified pipeline by its next investor.
- The buyer decides early and in silence. 6sense found buyers contact a vendor 61% of the way through the journey; Gartner reports 75% of B2B buyers prefer a rep-free experience. The founder’s network reaches the first buyers; the engine has to reach the rest.
- Each stage has one thing to ignore: paid media at seed, a second channel before the first works, a full-time CMO before the engine exists, and a brand refresh before the number is repeatable.
- Judge each stage by what it hands to the next: a named buyer and a claims register, a channel with a measured cost per opportunity, an engine with an owner, and a forecast the board trusts.
Health tech startup marketing is a different job at each funding stage, and most of the waste comes from doing a later stage’s job too early. A seed-stage company running paid campaigns has bought traffic to a page that cannot convert a committee. A Series A company hiring a full-time CMO has bought five days of judgement it can use for two. The priorities change every twelve to eighteen months, and the marketing that fits one stage is usually the wrong spend at the next.
The money arrives on a schedule and expects pipeline on one. Rock Health recorded $6.4 billion of US digital health venture funding across 245 deals in the first half of 2025, with the average deal at $26.1 million. Each of those companies will be asked, before its next round, for qualified pipeline from sources other than the founder. Harvard Business Review’s study of growth stalls found 87% of the root causes within management’s control, and a stall in a startup is usually a stage’s job left undone.
This guide is for the founder or CEO of a HealthTech, digital health, MedTech or health SaaS startup from pre-seed to Series B, in the US, the UK or Europe. Our companion on why HealthTech startups stall after early traction covers the plateau between stages two and three, and our pillar on the HealthTech marketing agency model covers who does the work at each stage.
A startup that markets like a Series B company at seed spends its runway on channels it cannot yet convert. Health tech startup marketing is a different job at every stage.
Why the health buyer sets the pace
6sense’s 2025 Buyer Experience Report, drawn from nearly 4,000 B2B buyers, found that buyers first contact a seller 61% of the way through their journey and that the vendor contacted first wins eight deals in ten. Gartner reports 75% of B2B buyers prefer a rep-free experience. A founder can be in the room for the first ten hospital buyers. The next hundred research in a room the founder cannot enter, and each stage of marketing exists to put something in that room.
1. Pre-seed to seed: find the buyer and the claim
The first stage of health tech startup marketing produces two sentences. One names the buyer by role, setting and moment. A director of nursing at a community hospital in the month after an incident report, or a clinic owner comparing three booking systems before a second location opens. The second is the claim the product can make today, read against its regulatory status. Everything else at this stage, the website, the deck, the first pages, is written from those two sentences, and nothing is spent on reaching people until they exist.
How health tech startup marketing finds the buyer sentence
Health tech startup marketing starts with twenty conversations, in person or on video, with the people who have the problem, before a line of copy is written. Ask what they tried last, what it cost them, who else was in the decision and what they read before they decided. The sentence that repeats across ten of the twenty is the buyer. At Healthora, we have seen that seed-stage companies which do the twenty conversations tend to write a homepage that converts on the first attempt. Companies that skip them rewrite it three times in the first year.
The claims register: health tech startup marketing before the website
In the US, the FTC’s Health Products Compliance Guidance requires “competent and reliable scientific evidence” for health claims in advertising, and a device’s claims are bounded by its FDA classification. A seed-stage company writes its claims register now, with each claim, its evidence and its regulator. A claim that goes on the first website and comes off after a lawyer reads it costs more than the register would have. Our pillar on the HealthTech startup branding guide covers how the buyer and the claim become a position.
What health tech startup marketing ignores at seed
Paid media. A seed-stage company has no proof page, no references and no measured cost per opportunity. Paid traffic lands on a page that cannot convert a committee and teaches the company nothing except that the channel is expensive. Health tech startup marketing at seed spends on conversations and writing, and the first paid pound or dollar waits for the next stage.
2. Seed to Series A: prove one channel and build the proof
The second stage produces a channel with a measured cost per opportunity and the pages that let it convert. One channel, chosen from where the buyer sentence says the buyer researches, run to depth for two quarters and counted. In health that channel is usually search with an evidence page behind it, or references and referrals through the first customers and their clinical champions. Health tech startup marketing between seed and Series A is the discipline of doing one thing properly while every adviser suggests five.
The proof pages health tech startup marketing needs before Series A
Health tech startup marketing before Series A builds an evidence page with the outcomes the product can support, the method behind them and a named clinical author. Then a security and compliance page. The first two case studies, written around the buying committee’s seats. TrustRadius’s 2024 B2B Buying Disconnect, from 2,164 buyers, found 78% already knew the products they bought before the purchase began and 66% prefer established products. A startup is not established. The proof pages have to do the work reputation does for an incumbent. Google’s guidance on helpful content adds that its systems weight experience, expertise, authority and trust more heavily on health topics, so the evidence page is also the page that ranks.
Counting the channel: the health tech startup marketing number investors ask for
Every opportunity is logged with its source, and the founder’s own introductions get their own line. The point of this stage is to show the next investor a source of pipeline that is not the founder. By the end of two quarters the company knows what one qualified opportunity costs from the chosen channel. That number is the most valuable thing health tech startup marketing produces before Series A. A company that arrives at the raise without it is asking the investor to take the engine on trust. Our guide to HealthTech demand generation covers the counting.
The thing to ignore between seed and Series A
A second channel before the first one works is the health tech startup marketing temptation between seed and Series A. The temptation arrives in month three, when the first channel has produced two opportunities and a conference invitation lands. Adding the second channel halves the depth of the first and doubles the things to count. The company reaches the raise with two channels that each half-work and no cost per opportunity for either.
3. Series A to B: build the engine and the team
The third stage produces an engine with an owner. One channel becomes three, run to depth: search with the evidence page, references and referrals as a programme, and email to the pipeline the company already owns. The proof pages become a set, with the integrations and pricing model pages added for the technical and procurement seats. And someone in the building owns the number. That is a marketing lead, a fractional CMO on two days a week, or a strong manager with a specialist agency behind her. Health tech startup marketing at Series A is where the founder stops being the marketing department.
Choosing who owns the health tech startup marketing number
Gartner’s 2025 CMO Spend Survey of 402 marketing leaders found 59% saying their budget cannot deliver their strategy and 39% planning to cut agency spend, which describes companies that hired the leader before they built the engine. At Series A the judgement of a CMO is needed for two days a week and the hands of a specialist team for five. Our guide to the fractional CMO for HealthTech covers the two-day model, and our guide to HealthTech agency vs in-house compares the hands.
The health tech startup marketing report that proves the engine exists
One page of health tech startup marketing reporting a month: qualified opportunities by source with the founder’s line separate, cost per opportunity by channel and for the trailing quarter, and cycle length by stage so the seat that stalls deals is visible. McKinsey’s 2024 B2B Pulse, from nearly 4,000 decision makers, found buyers use an average of ten channels; the report shows which three of the ten the company has earned the right to be in. At Healthora, we have seen that Series A companies which produce this page every month tend to raise their next round on the engine rather than on the story. The conversation with investors changes from promise to forecast.
The thing to ignore at Series A
A full-time CMO before the engine exists. A senior hire into a company with one channel and no report spends her first two quarters building the basics. Together, a fractional leader and an agency would have built them for a fraction of the cost. The equity and the salary are gone either way. Hire the full-time leader when the engine is producing and the constraint is scale.

4. Series B onward: scale what is measured
The fourth stage produces a forecast. With three channels measured and an owner in place, the company adds the fourth channel that the first three have earned. Usually that is paid media against the evidence pages, account programmes for the top fifty organisations, or events chosen from where the committee gathers. Each is judged against the measured cost per opportunity from the first three. The report becomes a forecast the board can plan against. Health tech startup marketing after Series B is the work of spending more money at the same cost per result.
Adding the fourth health tech startup marketing channel
Paid media enters health tech startup marketing now because the pages it sends buyers to exist and convert, and the cost per opportunity it has to beat is known. Account programmes enter because the committee map has been filled in from the deals won and the reference customers exist for each seat. Events enter because the company knows which three conferences the buyer sentence describes. Gartner found paid media taking 30.6% of marketing budgets across industries; a health company that reaches that share before this stage has usually bought it too early.
What the health tech startup marketing team looks like after Series B
A marketing leader who owns the forecast, one or two generalists in the building, and specialists outside it for the disciplines the company still cannot employ at depth: technical search, conversion design, content at volume. The ANA’s in-house agency study found 82% of member companies now have in-house capability and 92% of those still use external agencies, and health tech startup marketing teams at this stage run the same hybrid. Our guide to outgrowing a HealthTech marketing agency covers when the balance shifts.
The thing to ignore after Series B
A brand refresh before the number is repeatable. New money often arrives with a wish to look like the company the round implies. A rebrand then consumes two quarters of the team’s attention while the engine is left running on its own. Refresh the brand when the forecast has held for two quarters. The constraint should be recognition rather than conversion. Our guide on when to rebrand a health brand covers the timing.
Health tech startup marketing in practice: what each stage hands to the next
Health tech startup marketing that follows the four stages runs on handovers. Seed hands Series A a named buyer, a claims register and a homepage written from both. Series A hands Series B one channel with a measured cost per opportunity, an evidence page with a named author, a security page and two case studies. Series B hands the scale stage three channels measured, an owner of the number, a monthly report and a proof set the technical and procurement seats can read. The scale stage hands the board a forecast, a fourth channel judged against the first three, and a team that runs without the founder.
Companies whose health tech startup marketing respects the handovers usually notice the change first in the fundraise. The investor’s question moves from “how will you find customers” to “what does one cost”. The answer is on a page rather than in a story. Then the report begins to show the engine’s share of pipeline rising past the founder’s. The next stage’s priorities are funded on evidence rather than on the size of the round.
The recap below lists the four stages of health tech startup marketing, what each produces and what each ignores.
- Pre-seed to seed: find the buyer and the claim. Twenty conversations, a buyer sentence, a claims register, a homepage written from both. Ignore paid media.
- Seed to Series A: prove one channel and build the proof. One health tech startup marketing channel to depth for two quarters, counted by source, plus the evidence page, the security page and two case studies. Ignore a second channel.
- Series A to B: build the engine and the team. Three channels, the full proof set, an owner of the number and a one-page monthly report. Ignore a full-time CMO before the engine exists.
- Series B onward: scale what is measured. A fourth health tech startup marketing channel judged against the first three, a forecast the board trusts, a hybrid team. Ignore a brand refresh before the number holds.
Each stage of health tech startup marketing can be run by the founder with a good adviser, by a specialist agency with a strategy layer, or by the hybrid that most companies reach by Series B. Our guide to the HealthTech marketing consultant covers the adviser model, and our services and case studies show what the agency route looks like at each stage.
A specialist in health understands that the buyer researches in silence, that every claim answers to a regulator, and that a hospital’s buying cycle will outlast a startup’s patience. Do the stage’s job, hand the next stage what it needs, and ignore the one thing each stage is tempted by. Health tech startup marketing done in that order reaches each round with a number rather than a story.

What should health tech startup marketing spend at seed?
Conversations and writing, and almost nothing on reach. Twenty buyer conversations, a buyer sentence, a claims register read against the product’s regulatory status, and a homepage written from both. Health tech startup marketing at seed exists to find out who buys and what can be claimed. Paid media at this stage buys traffic to a page that cannot yet convert.
When should a HealthTech startup hire its first marketer?
Health tech startup marketing needs its first hire between seed and Series A, once one channel is running and needs counting, and usually as a generalist who owns the report and briefs specialists rather than as a senior leader. The judgement of a CMO is useful from Series A, on two days a week as a fractional leader. A full-time marketing leader fits once the engine is producing and the constraint is scale.
Which channel should health tech startup marketing start with?
The one the buyer sentence points to. For most companies selling to hospitals and health systems that is search with an evidence page behind it, because the committee researches before it calls. For companies with a handful of strong early customers it is references and referrals through their clinical champions. Pick one, run it to depth for two quarters, and count it before adding another.
How much should a HealthTech startup spend on marketing?
Size it from the pipeline the next round expects rather than from a percentage of revenue, and shape it by stage. Conversations and writing at seed; one channel and the proof pages before Series A; three channels and an owner of the number at Series A; a fourth channel and a forecast after Series B. Book a consultation for a view on the right structure for your stage.
What do investors want to see from health tech startup marketing?
Investors want health tech startup marketing to show a source of qualified pipeline that is not the founder, with a measured cost per opportunity. At seed they will accept the buyer sentence and the claims register. By Series A they want one channel counted for two quarters, and by Series B three channels, an owner and a monthly report. After that they want a forecast that has held.
Should a HealthTech startup use an agency or hire in-house?
Both, in a health tech startup marketing ratio that shifts by stage. Early on, a specialist agency supplies disciplines the company cannot employ, with the founder or a generalist owning the number. From Series A a marketing lead or a fractional CMO owns the number in the building and the agency supplies the hands. After Series B the team grows and the agency covers the disciplines still too specialist to employ at depth.
What is the most common health tech startup marketing mistake?
The most common health tech startup marketing mistake is doing a later stage’s job too early. Paid media at seed, a second channel before the first is counted, a full-time CMO before the engine exists, and a rebrand before the number is repeatable. Each spends money the stage needed for its own job, and each leaves the next round without the handover it expects.
