How do you find your first growth channel before hiring a marketer?

By Ronan Liedmeier, fractional head of growth · Published 15 October 2026 · Last updated 15 October 2026

Run two cheap channels yourself for six weeks, keep the one that books meetings with people who sign, and hire a marketer only once that channel has produced customers for two quarters. How I find the first channel, land the first ten B2B customers without ads, and choose between a fractional lead, an agency and a first hire.

You find the first growth channel by running two cheap channels yourself for six weeks, counting replies and meetings booked, and keeping the one that produces conversations with the people who sign. You hire a marketer after that, because a marketer without a proven channel spends the first two quarters doing your discovery work at a salary. That rests on ten years in growth across 30 or more clients, three companies I co-founded by 23, and the first-marketing-hire seat at Fangage, which I held through its acquisition by Triller.

A growth channel is a repeatable way of putting your product in front of people who can buy it, where you know what one conversation costs and the next hundred conversations look like the last ten. Before product-market fit, a channel is a hypothesis you test for a few weeks with your own hours.

How do I find the first growth channel for my startup?

Score six channels on what they cost to start, how fast they tell you something, and whether your buyer is there, then run the two cheapest ones that fit for six weeks. In B2B with a sales conversation in the deal, founder-led outbound wins the first round in nearly every company I have worked with, because the founder hears the objections directly.

Lenny Rachitsky asked the founders of about twenty hyper-growth B2B companies how they found their first ten customers. His finding: "Only three sourcing strategies account for every B2B company's very early growth": the founders' own network, going to where the customers already gather, and press, which he calls rare as a starting point (Lenny's Newsletter). None of the three needs a marketer.

Here is how I score the six channels a pre-seed to Series A founder can run without a hire.

Channel	Cost to start	Time to a reading	Fits	Does not fit	What you learn
Founder-led outbound (LinkedIn; email where it is legal)	Low: your hours, one outreach tool seat	Days to weeks	B2B with a sales call in the deal	Self-serve at a low monthly price; consumer	The objections, the buyer's words, who signs
Job-board and intent sourcing (job posts, briefs, RFPs)	Low: your hours, an enrichment tool	Days to weeks	Services; tooling that replaces or supports a hire	Products with no hiring or procurement footprint	Who has budget and a deadline now
Content and AI search (answer pages, templates, comparisons)	Low cash, high time	Months	Problems people already search for	New categories nobody searches for yet	What people call the problem when they type it
Paid (Google, Meta, LinkedIn ads)	Medium to high cash	Days for clicks, weeks for sales	Existing search demand; self-serve or short cycle	Long enterprise cycles; no working funnel yet	Click cost and page conversion; little about why people buy
Partnerships and integrations	Low cash, slow	Months	Products that sit inside another tool's workflow	Pre-PMF products with nothing to integrate	Whose customers overlap yours
Community (Slack groups, forums, events)	Low cash, high time	Weeks	Developer tools; buyers with a visible practitioner group	Buyers who are not in any group online	Your users' vocabulary, and who the loud ones are

Three questions decide the score for each row. Can I start it this week without hiring? Will I know inside six weeks whether it works? Does the buyer live there? Two yeses and a maybe gets a slot in the sprint.

A channel that fits the buyer but takes months to show anything, like content, I start in week one and expect nothing from until the quarter is out. The first two rows are where the first ten customers come from in almost every B2B company I have seen under twenty people.

One regional change to the table. If your buyers sit in Germany, Austria or Switzerland, cold B2B email is ruled out under UWG section 7 in Germany, the TKG in Austria and UWG Art. 3 in Switzerland. There, LinkedIn is the outbound channel, in formal Sie-form, with a ceiling of two touches on a cold contact. A referral works when the referrer is named in the opening line.

How do I get the first 10 B2B customers without paid ads?

You get the first ten by finding companies that have already written down the need, reaching the person who owns the budget away from the platform where they wrote it, and sending a short note that proposes a way to solve the problem instead of applying for the job. This is the method I run for my own pipeline at GMS, and it transfers to any product that replaces or supports a role a company is hiring for.

Paul Graham's essay on unscalable work is still the base text. His line on early users: "You have to go out and get them" (Paul Graham). The question is where to go. My answer is: where the need is already public.

Find the need where it is written down. Job postings for a growth marketer, an SDR, a content lead, a data analyst. Agency briefs on freelance platforms. Tenders and RFPs. "We're hiring" posts on LinkedIn. A company that publishes a job description has told you the problem, the tools they use, the seniority they can afford and the person the role reports to. I treat every such posting in my segment as a lead, because the founder who wrote it has already done my qualification for me.
Identify the decision maker off-platform. The posting names a team or a reporting line. Apollo or a LinkedIn search gives you the founder or the COO who owns that budget. I never apply through the form. The form goes to a recruiter or into a pile of two hundred applicants. The founder reads LinkedIn.
Send a direct note instead of applying. Under 300 characters on the connection request: one observation lifted from their own posting, one question a busy person can answer in a sentence, a sign-off. No deck and no calendar link. The note works because it proves you read the posting, and because a founder would rather answer a question about their own plan than open a PDF.
Two touches, then stop. The second touch, after they accept, answers one thing from their reply or their posting. If nothing comes back, the account gets a re-check date and I move on.
Track every account on a board with a stage and a lost reason. Mine is in Notion. The lost reasons after the first fifty accounts tell you which segment to drop and which objection to answer on the website.

For a product company, swap "the role I do" for "the role my product replaces or supports". A company hiring a second SDR is a lead for sales automation. A company posting for a first marketer is a lead for anyone who sells pipeline, content or ads, and is also a company that has not found its first channel yet.

The division of labour I run: the tools source the postings, enrich the contact and draft the first version of the note (Apollo for enrichment, HeyReach for LinkedIn sends, Claude skills for drafts, and an audit for machine-written phrasing before anything goes out). I read every posting, judge every draft and send every message myself. A founder with four hours a day can run the same loop without the tooling, slower.

What counts as done: ten customers who paid. In Lenny Rachitsky's B2B product-market fit survey, most founders said they felt real fit with 3 to 10 paying customers, and the median time from idea to that feeling was about two years (Lenny's Newsletter). Ten paying customers from one channel is also the number at which a first hire has something to run.

When should I hire my first marketer instead of keeping a fractional lead?

Hire a full-time marketer when one channel has produced paying customers for two consecutive quarters and the job is to run it harder. Keep a fractional lead while the job is still to find that channel, because a first hire needs a channel to run and a fractional lead's job is to make one exist.

I was the first marketing hire at Fangage and stayed through its acquisition by Triller. What I took from that seat: a first marketer is productive in proportion to how much the founders already know about who buys and why. A first hire into a company with zero proven channel spends the first quarter doing the founder's discovery work, at a salary, with less authority to change the product than the founder has.

Stage	Typical team	Who owns GTM	What to buy	What not to hire yet	When to move on
Pre-seed	Founders, maybe one or two engineers	One founder, at least half of each day	A GTM sprint or an advisory retainer to pick two channels and set up the pipeline	A head of marketing; an agency on a monthly retainer	Ten paying customers from one channel
Seed	Under twenty people, mostly product and engineering	Founder plus a fractional head of growth	A fractional engagement of three to six months that builds the system; one contractor executing inside it	A VP of marketing; a generalist "owns all marketing" hire	One channel with a known cost per customer, held for two quarters
Series A	Twenty and up, first sales or CS hires	First full-time growth or marketing lead	The person who will run the proven channel; the fractional lead moves to advisory or to a second channel	A second agency before the first hire has landed	Second channel proven; a team of two or three under the lead

The test I use for whether a channel is ready to hand over is the one Sean Ellis built. Ask users how they would feel if they could no longer use the product. He ran it across nearly a hundred startups and found "the magic number was 40%" very disappointed: companies above it grew, companies below it struggled. Superhuman started at 22% and built its roadmap around the gap (First Round Review). Below 40%, the hire you need is in product, and the growth work stays with the founder and a fractional lead.

One more reason to wait. A first marketer hired before the channel is known will pick the channel they already know: a paid-media person runs ads, a content person starts a blog. That is a decision you should not let a hire make by default.

What does a six-week GTM sprint deliver?

A six-week GTM sprint delivers a tested first channel, a live pipeline with the first conversations in it, and a written decision on what to run next and who should run it. It replaces the two quarters a founder spends guessing, or the two quarters a premature hire spends ramping.

This is the fixed-scope package I run with early-stage founders. The founder's time in it is around four hours a week plus the sales calls it produces.

Week	Work	Output	Decision at the end of the week
1	Buyer and positioning. Interviews with the last customers and the last lost deals. Review of every closed and lost conversation. One-page positioning in the buyer's words.	Named segment, the problem stated the way buyers state it, a list of who signs and who blocks	Which two channels to run
2	List and message. Build the target list from job posts, intent sources and enrichment. Write two outbound variants. Set up the outreach tool and the pipeline board.	A list of accounts with a named decision maker on each, two message variants, a working pipeline	Go live, or fix the list first
3	First touches. Send daily, read every reply, rewrite the note after the first batch of replies.	Reply rate and meetings per variant, first objections written down	Kill the weaker variant
4	Second channel. Launch the slow channel alongside outbound: one answer page, one template download, or one partner conversation.	First page live or first partner call held, outbound still running	Keep the second channel or cut it
5	Read the numbers. Cost per conversation in hours and cash, meetings per hundred contacts, objections grouped, lost reasons tagged.	A one-page channel scorecard	Double on one channel
6	Handover. Write the channel guide, the dashboard, and either a hiring brief or a fractional scope for the next quarter.	Channel guide, metric dashboard, 90-day plan, hiring brief	Hire, extend, or run it yourself

The week-one interviews are the part founders try to skip. Ten conversations with buyers and with people who said no produce the sentence that goes at the top of every message in week two. Without them, week two is guesswork dressed up as copy.

Week four exists because the slow channel has to start early to pay off later. At a resource-planning SaaS, the founder produced planning templates, I did the keyword research and built the download pages with a contact button inside each sheet instead of a gate in front of it. That grew to roughly 10,000 monthly organic visits with a conversion-rate uptick, and the first months showed almost nothing. I left before the final results were in, so I quote the traffic and the direction and no revenue figure.

Which GTM metrics should I track before product-market fit?

Before product-market fit, track eight numbers: reply rate by variant, meetings per hundred contacts, meeting-to-next-step rate, win rate, median sales cycle, cost per customer in founder hours and cash, activation and 30-day retention, and the share of users who would be very disappointed without you. CAC payback and ARR growth belong in the next stage, because with a handful of customers the denominators are too small to read.

#	Metric	How to count it	Why it matters before PMF	What it tells you to change
1	Reply rate	Replies divided by contacts sent, per variant	The cheapest reading, available in week three	The message or the list
2	Meetings per 100 contacts	Booked meetings divided by contacts, times 100	Separates curiosity from intent	The segment
3	Meeting-to-next-step rate	Trials, pilots or proposals divided by meetings held	Shows whether the problem is worth acting on	The offer and the demo
4	Win rate	Closed won divided by all closed	Pattern or luck	Pricing and objection handling
5	Median sales cycle	Days from first touch to signature, won deals	Decides which channels you can afford	Who you target in the account
6	Cost per customer, hours and cash	Founder hours plus spend, divided by customers won, per channel	The precursor to CAC	Which channel to drop
7	Activation and 30-day retention	Share who reach the first value event; share still active after 30 days	Separates sold from used	Onboarding and the product
8	"Very disappointed" share	Sean Ellis survey; 40% is the public benchmark	The one PMF number with a published threshold	Scale the channel or keep searching

The first six are channel metrics and come out of the pipeline board without extra tooling. The last two are product metrics and need an event in the product and a survey. A founder who tracks the first six and ignores the last two will scale a channel into a product people stop using.

a16z's list of GTM metrics for B2B startups puts CAC payback at about 12 to 18 months for an average startup, 6 to 12 for SMB and 18 to 24 for enterprise (a16z). Those are Series A numbers. A founder with four customers cannot compute a payback that means anything, so I track the inputs (hours, spend, customers per channel) and compute payback on the day it has a denominator.

The reason to count any of this early is in the failure data. CB Insights reviewed 431 VC-backed companies that shut down since 2023; 70% cited running out of capital and 43% cited poor product-market fit (CB Insights). Capital runs out because the channel never got found or the product never got used. The eight numbers above show both earlier than the bank balance does.

Fractional head of growth vs agency vs first hire: which should I pick?

Pick a fractional head of growth when the job is to find and prove the first channel, an agency when the channel is proven and the job is volume in the channel that agency specialises in, and a first full-time hire when a channel is producing customers and someone needs to run it every day. Each option is bad at the other two jobs, and most of the expensive mistakes I have seen at seed stage come from buying one of them for a job it cannot do.

Criterion	Fractional head of growth	Agency	First full-time hire
Cost structure	Fixed scope per project, or three to six months; no media markup; ends at handover	Monthly retainer, in paid media often plus a share of spend; minimum terms; grows with the budget	Salary, equity, recruiting cost and ramp time; the most expensive option if the hire is wrong
Speed to a first result	Weeks; starts on the founder's existing conversations and tools	Weeks in its own channel; months outside it	Months; recruiting plus onboarding before the first campaign goes out
Ownership	Strategy and the system: pipeline, measurement, outreach, the channel guide; hands all of it over	Execution inside its channel; strategy stays with the founder	Everything from day one, including the questions nobody has answered yet
Access to the founder	Direct; sits in deal reviews and the week-five readout	Through an account manager; the strategist is shared across clients	Direct
What it is bad at	Running a channel at volume for years; being in the building every day	Choosing the channel; telling you to stop spending with them	Finding the first channel with no budget and no senior sounding board
Right moment	Pre-seed to seed, or a new market at any stage	A proven channel with a budget to scale	Series A, or seed with one proven channel and two quarters of customers from it

Agencies have a structural reason to keep you in their channel: their revenue is tied to it. That is fine once the channel is proven. Before that, you are paying someone whose incentive is to prove the channel works rather than to find out whether it does.

A fractional lead's weakness is the one the other two are good at: daily presence over years. The engagement is built to end. If a founder wants someone in the office five days a week in month three, the right move is to use the fractional months to write the brief and run the hiring loop for that person.

This is the work GMS does with early-stage founders. A six-week GTM sprint to find the first channel, or a fractional head of growth engagement for three to six months to build the system under it and write the brief for the hire who takes it over. The first step is a call where I go through your pipeline and your last ten lost deals.

What should I do this month if I have no marketer?

Run the first two channels from the table yourself, for four hours a day, and keep a tally. Here is the order I would do it in.

Write down who signed your last five deals and why, in the words they used on the call. With fewer than five deals, write down the last five people who said no and what they said.
Pull fifty job posts, briefs or tenders that describe the problem your product solves or the role it supports. Put each on a board with the company, the posting, the stated problem and a re-check date.
Find the decision maker for each account away from the job board. Send a connection note under 300 characters: one line from their posting, one question. For German-speaking buyers, LinkedIn only, Sie-form, two touches. Add a stage and a lost reason to every account and read the lost reasons every Friday.
Ship one page that answers the question your buyers type most, with the template they would download and a way to contact you inside it. Expect nothing from it this quarter.
After six weeks, count replies, meetings and next steps per variant. Keep the channel that booked meetings with people who can sign.
Hire a marketer when that channel has produced customers for two quarters. Until then, buy senior time by the project and keep the selling with you.

FAQ

How long does it take to find a first growth channel?

Six weeks gets you a reading on two channels: reply rate, meetings booked, and the objections you heard. A quarter of the same channel tells you whether the first reading holds. Product-market fit takes longer; in Lenny Rachitsky's survey of B2B founders the median was about two years from idea, and most felt it with 3 to 10 paying customers.

Should a technical founder do the first sales calls personally?

Yes, until at least ten customers have paid. The founder hears the objections first-hand and learns the buyer's words for the problem, which is what every later message, page and hire is built on. A hired marketer or agency hears those objections second-hand and later.

Can I use cold email to reach B2B buyers in Germany?

No. Cold B2B email is ruled out in Germany under UWG section 7, in Austria under the TKG and in Switzerland under UWG Art. 3. LinkedIn is the outbound channel there, written in formal Sie-form, with a two-touch ceiling on cold contacts. A referral contact is fine when the referrer is named in the first line.

What reply rate is good for founder-led outbound?

I do not trust a public benchmark for this, because reply rate depends on the list, the sender's profile and the market. Compare two message variants against each other on the same list and judge by meetings booked rather than replies. A high reply rate with no meetings means the note is polite and the offer is weak.

What is a fractional head of growth?

A senior growth lead who works with a company part-time for a defined period, by project or for three to six months, setting the strategy and building the pipeline, measurement and outreach systems that execute it. The role ends with a handover to a full-time hire or a reduced advisory scope. It is a fit from pre-seed to Series A, or for a company opening a new market.

When are paid ads the right first channel?

When people already search for the problem you solve and the sale is self-serve or closes in one or two calls. Paid gives a click and a landing page conversion rate within days, but tells you little about why people buy. For a new category or a product with a sales conversation in the deal, run outbound first and use the language you hear to write the ads later.
