What is growth marketing (a practitioner's definition)

Growth marketing is running experiments across the full customer journey to find what actually grows the business, then doing more of that.

That’s the whole thing. Not a department. Not a campaign type. A way of working where you test first, measure fast, and scale what wins. Everything else you’ll read about growth marketing (data-driven, full-funnel, iterative) is technically true but tells you nothing useful. It’s like defining cooking as “heat-based food transformation.”

I’ve spent ten years doing this for brands like Storytel, felyx, and Nestlé. Here’s what it actually looks like, stripped of the LinkedIn polish.

What is growth marketing

Growth marketing isn’t “a type of marketing.” When Sean Ellis coined “growth hacking” in 2010, he deliberately avoided the word “marketing.” Marketing means a department. Growth means a mandate that cuts across marketing, product, engineering, and data.

Ellis was the first marketer at Dropbox. He defined a growth hacker as “a person whose true north is growth.” Two years later, Andrew Chen’s essay “Growth Hacker is the new VP Marketing” hit the front page of Hacker News and spread the term across Silicon Valley. He called it “a hybrid of marketer and coder.”

That was the cowboy era. Growth hackers were the folks who used tricks and loopholes to juice signups. Some of those tricks were clever. A lot of them were shady (fake countdown timers, dark patterns, pre-ticked checkboxes). By 2024, regulators started fining for that stuff. The EU’s Digital Services Act, CCPA, India’s DPDPA. And companies started measuring retention instead of just signups, which made the hack-driven funnels look a lot less impressive.

The term “growth hacking” quietly died. The mandate stayed. “Growth marketing” became the default label.

My take: The name change wasn’t just fashion. It reflected a real shift: from tricks to systems, from signups to retention, from one clever person to a cross-functional team. If you hear someone say “growth hacking” in 2026, they’re usually selling a course.

So what does a growth marketer actually do? Three things, over and over:

1. Find the bottleneck. Where are you losing people? Signup? First use? Month two? You can’t fix what you can’t see.
2. Run a test. Change one thing, measure the result, decide fast.
3. Scale or kill. If it worked, put more behind it. If it didn’t, write down what you learned and move on.

That’s growth marketing. Simple to say. Hard to do well. The hard part isn’t knowing the method. It’s having the patience to keep running experiments when 88% of them don’t work.

Growth marketing vs traditional marketing

Every article on this topic does a comparison table. Here’s the honest version:

Neither is “better.” They solve different problems. If nobody knows your brand exists, you need traditional marketing. If people find you but don’t stay, you need growth marketing.

The real gap shows up in how teams spend their time. Traditional marketers spend most of their energy on getting people in the door (acquisition). Growth marketers spend about 80% of their time on what happens after someone shows up: did they have a good first experience? Did they come back? Did they tell anyone?

That surprises people. Most folks assume marketing equals “getting more eyeballs.” Growth marketing is “getting more eyeballs and keeping them.”

A good growth marketer also knows which channels compound over time. Paid ads stop working the day you stop paying. But something like SEO, the free channel that compounds, keeps paying for years. Especially now that there are solid AI tools for SEO that cut the grunt work in half. A growth team thinks about both: the quick win today and the slow build that pays for a long time. That’s also where AI content strategy fits in: using AI to move faster on the channels that compound.

What a growth marketer’s week actually looks like

Every definition I’ve read describes growth marketing in abstract frameworks. None of them show you the actual work. Here’s a realistic week, based on what it looked like when I ran growth for brands like Storytel and felyx.

Monday. Review last week’s experiment results. Most didn’t work. Kill the losers, note what you learned, double down on anything that worked. Update the experiment tracker (usually a spreadsheet, sometimes a tool, rarely anything fancy).

Tuesday. Dig into retention data. Where are people dropping off? Is it the onboarding? The second visit? The payment step? Pull up the numbers, form a theory about why.

Wednesday. Build and ship a new test. A different landing page, a change to the welcome email, a pricing experiment. Keep it small enough to learn from quickly. The best AI marketing tools help you build these faster, but the thinking is still yours.

Thursday. Cross-functional sync. Talk to product: what’s shipping next week and how should we position it? Talk to data: is the test from Wednesday collecting the right signals? Talk to customer support: what are people complaining about? Growth marketing lives in the gaps between teams.

Friday. Document what you learned. Update the experiment backlog. Plan next week’s tests. The backlog is the most important thing a growth marketer maintains. Without it, you’re reacting. With it, you’re compounding.

Here’s the unglamorous truth that no definition will tell you: most experiments fail.

Optimizely’s platform data shows only about 12% of experiments produce a clear winner. A separate dataset from CXL, covering 28,304 experiments, found that only 20% even reached statistical significance (enough data to be confident in the result). But the experiments that do win improve results by an average of 61%.

The job isn’t being right. The job is being fast enough that the wins compound.

Booking.com runs about 25,000 tests per year. That’s roughly 70 per day. The median company? Two to three per month. That velocity gap is the growth marketing gap.

My take: If you’re running fewer than one experiment per week, you don’t have a growth marketing program. You have a marketing team that occasionally tests things. The difference matters.

The AARRR framework (and why it matters)

In 2007, Dave McClure created a framework he called “pirate metrics” (because it spells AARRR). He built it because startups were drowning in numbers that didn’t matter, things like page views and follower counts, and ignoring the ones that did.

Here’s what each letter means, in plain words:

• Acquisition: How do people find you? Search, ads, social media, word of mouth. The “getting noticed” part.
• Activation: Do they have a good first experience? Did they sign up, try the product, and think “this is useful”? Or did they bounce?
• Retention: Do they come back? This is the one most people skip, and it’s the one that matters most. A customer who comes back ten times is worth more than ten customers who come once.
• Referral: Do they tell others? Real referrals (a friend texts you a link) are worth more than any ad, because trust comes pre-built.
• Revenue: Do they pay you? And does it cost less to get them than they’re worth over time?

Traditional marketing lives mostly in the first bucket (acquisition). Growth marketing works across all five.

Here’s the part that surprises people: most experienced growth marketers spend 80% of their time on activation and retention. Not acquisition. Getting people to your door is a solved problem (buy ads, write content, run AI marketing examples that bring in traffic). Getting them to stay? That’s where the real leverage lives.

If you want to build a simple AI marketing strategy around this framework, start by mapping your biggest drop-off. Where are you losing the most people? That’s where to run your first experiment.

How to know if your company needs growth marketing

Not every company needs growth marketing. And hiring for it too early is worse than not hiring at all, because you’ll burn budget running experiments on a product that isn’t ready.

You probably need a growth marketer if:

1. You have a product people want (that’s called product-market fit) but you can’t figure out how to grow in a way you can predict
2. You’re getting customers but they’re not coming back
3. Your marketing team runs campaigns but nobody’s running experiments
4. Your CEO or board keeps asking “what’s our growth model?” and you don’t have a clear answer
5. You’re a small team and you need one person who can think across the whole customer journey

You probably don’t need growth marketing yet if:

1. You don’t have product-market fit. Fix the product first. Andrew Chen, the same person who helped popularize growth hacking, later wrote: “Startups don’t need growth hackers at first. They need products that are really working in the market.”
2. You don’t have enough traffic or customers to run meaningful experiments. If 50 people visit your site per week, you won’t learn anything from a test.
3. You need brand awareness from zero. That’s brand marketing, and it’s a different skill set.

A McKinsey survey found that 83% of global CEOs look to marketing as a major driver of growth. But HubSpot’s 2026 State of Marketing report found that 33% of marketers still say measuring ROI is their biggest challenge. That gap, between wanting growth and being able to prove what’s working, is the exact problem growth marketing exists to solve.

The good news for small teams: you don’t need a big staff to do this. AI for small business marketing has gotten good enough that one sharp person with the right tools can run a real growth program. HubSpot’s same survey found that 86.4% of marketing teams now use AI, and marketing output grew 24% while teams got smaller. One person with AI can out-experiment a five-person team without it.

If you recognize those signs and want someone who’s done this for real brands, that’s what I do.

Growth marketing interview questions (and what they reveal about the job)

Want to really understand what growth marketing is? Look at what companies test for when they hire growth marketers. The interview questions tell you everything about the actual job.

Andrew Chen collected real interview questions from growth teams at Atlassian, SurveyMonkey, Gusto, and HubSpot. Here are some of the real ones:

• “How would you growth hack a city?” (Gusto) Tests whether you can break a big, fuzzy problem into testable pieces. No right answer. The point is watching you think.
• “How many experiment ideas can you generate in 3 minutes?” (Gusto) Tests velocity. A growth marketer’s most important skill is generating ideas fast, not being right about any single one.
• “What apps would you immediately set up on a new work computer?” (Atlassian) Tests tool fluency. They want to know if you’ve actually done the work.
• “Describe your biggest setback, personally or professionally.” (HubSpot) Tests whether you’re comfortable talking about failure. If you’re not, you won’t last in a role where 88% of your experiments don’t win.

See the pattern? Nobody asks “do you know Facebook Ads?” or “can you run a Google campaign?” Those are skills you can learn in a week. What they test for is harder to teach:

• First-principles thinking. Can you solve a problem you’ve never seen before?
• Experiment velocity. Can you generate ideas faster than you can test them?
• Comfort with failure. Can you kill your own idea when the data says it’s not working?
• Cross-functional thinking. Can you talk to engineers, designers, and data people?

That skill stack, analytical thinking plus creative execution plus a thick skin, is growth marketing. If you’re preparing for a growth marketing interview, study the method, not the channels.

Glassdoor’s 2026 data puts the average Growth Marketing Manager salary at $129,919 per year in the US (range: $97K to $176K). Director-level roles average over $200K. The premium exists because that combination of analytical and creative is genuinely rare.

And it’s not a niche role anymore. LinkedIn’s labor market data showed that Growth Marketing Manager was the number-one fastest-growing job title in Canada and France between 2018 and 2022.

Where growth marketing is headed

Three shifts are changing the job right now.

1. AI is the multiplier. HubSpot’s 2026 survey found that marketing teams are producing 24% more output while operating with 15 to 22% fewer people. That’s not magic. It’s AI handling the repetitive parts (writing draft copy, analyzing data, building landing pages) while the human focuses on which experiments to run and what the results mean. If you want to see how this works in practice, here’s a deeper look at how to use AI in digital marketing. And here are the best AI tools for business making it possible.

2. From “growth hacker” to growth leader. The cowboy era is over. A peer-reviewed paper in the journal Technological Forecasting and Social Change found that growth hacking extends beyond marketing alone and beyond tech companies. Companies want senior operators who can build repeatable systems, not juniors who can hack one channel for a quarter. The professionalization is real.

3. Full-stack operators are winning. The solo operator who can think about growth, implement AI, write content, and analyze data is replacing the specialist. Not because specialists aren’t good. But because the tools caught up. What used to require five people now requires one person who knows which tool to reach for. This is probably the single biggest shift in growth marketing since Ellis coined the term. Whether you’re creating content with AI or automating reports, the amount of ground one person can cover has grown tenfold.

This is exactly what I’ve rebuilt my own practice around. I spent years running growth the traditional way (big team, lots of meetings, slow experiment cycles). Now I run it with AI, and the cycle time dropped from weeks to days. The leverage is real, and it’s available to anyone willing to learn the systems.

FAQ

What is meant by growth marketing?

Growth marketing is a full-funnel approach to growing a business through rapid experimentation. Traditional marketing focuses mostly on awareness and getting new customers. Growth marketing also works on keeping those customers (retention), getting them to tell others (referral), and increasing what they spend (revenue). The core method is: test something small, measure whether it worked, learn from the result, and either scale the winner or move on.

What are the 4 marketing growth strategies?

The classic framework is called the Ansoff Matrix. It has four strategies: market penetration (sell more of what you have to the customers you already have), market development (take what you have to a new market), product development (build something new for your current customers), and diversification (build something new for a new market). Growth marketers use all four but let experiment data decide the sequence, not a strategy deck.

Is growth marketing just marketing with a new name?

Fair question. Some people argue yes. Intercom’s take was blunt: “Growth doesn’t come from silver bullets. Growth comes from winning a thousand tiny battles: 0.5% here, 1% there.” The honest answer: the underlying skills (understanding customers, writing well, reading data) aren’t new. What’s different is the method (experiment first, then scale), the scope (the whole customer journey, not just acquisition), and the speed (weekly test cycles, not quarterly campaigns). If your marketing already works this way, you’re doing growth marketing. Most marketing doesn’t.

What does a growth marketer actually do day-to-day?

Run experiments, analyze results, kill what doesn’t work, scale what does, repeat. Most of the week is spent on retention and activation (keeping customers and improving their first experience), not on acquisition campaigns. See the “What a growth marketer’s week actually looks like” section above for a full breakdown. It’s less glamorous than the job description suggests. 58% of companies still make changes based on opinions, not data. The growth marketer is the person who insists on running the test first.

How much do growth marketers make?

Glassdoor’s 2026 data: Growth Marketing Manager averages $129,919 per year in the US (range $97K to $176K). Senior roles like Director of Growth Marketing average over $200K. The Bureau of Labor Statistics projects marketing manager employment will grow 6% from 2024 to 2034, faster than average, with about 36,400 openings per year. The role pays well because it requires a rare combination: someone who can think analytically and execute creatively.
