Review of the Book "Hacking Growth" by Sean Ellis and Morgan Brown: On Methods for Rapid Business Growth
Sean Ellis and Morgan Brown don’t bore the reader with dry pedagogy, but share their secrets with the excitement and liveliness of mentors—secrets once used by:
- Airbnb
- Dropbox
When the market was filled with uncertainty and it seemed that only the chosen ones could “survive” the innovation race: a multiple increase in user base within a year — this is not a fairy tale, but the result of applying their methods.
The authors aren’t afraid to expose the mistakes of industry leaders and show that flexible thinking and a willingness to experiment are the only ticket to a future where the rules of the game change faster than a smartphone notification arrives.
While reading, you can’t shake the feeling that you’re not being lectured, but engaged in a conversation; there’s not a drop of obligatory preaching — only an honest dialogue, where every example is backed by a real name and a real number.
Key Concepts and Their Analysis
The authors of "Hacking Growth," Sean Ellis and Morgan Brown, share their approach to rapid business development through experimentation, data, and teamwork. Here are the main ideas of the book and a brief analysis of each:
This is a dedicated team of marketers, developers, analysts, and product managers that focuses solely on growing the product or business.
✅ Pros: Fast decision-making, strong result orientation.
⚠️ Cons: Difficult to implement in large companies with established structures.
To grow, you need to constantly test hypotheses and experiment with ideas (for example, through A/B testing).
✅ Pros: Growth becomes manageable, and the risk of errors is reduced.
⚠️ Cons: Requires time, resources, and proper analytics.
It’s better to launch “raw” ideas quickly than to polish them for too long.
✅ Pros: Fast learning and adaptation.
⚠️ Cons: Possible flaws and lower quality.
Marketing won’t help if the product doesn’t solve the user’s problem or spark interest.
✅ Pros: A strong product “grows on its own.”
⚠️ Cons: Requires close collaboration between teams (which isn’t always easy).
This isn’t just a set of tools, but a survival guide in a field where only those who learn fastest and aren’t afraid to ditch the old for the new come out on top.
Who the Book Is For
There’s no room here for daydreamers with rose-colored glasses — the target audience is clearly defined: those who live on the edge of change and aren’t afraid to challenge established rules every single day.
In focus: executives, startup teams, and product managers for whom the phrase “exponential growth” isn’t just a buzzword but a daily headache — and a driving force.Readers won’t be left alone with their questions: the authors generously provide a roadmap filled with examples of rapid transformations in real companies.
It’s shown how:
- daily testing
- continuous adjustments
- working with real metrics
Developers, marketers, business owners — anyone who understands that without constant experimentation and a flexible strategy, survival today is impossible — will find not just inspiration here, but practical checklists, tools, and frameworks ready to implement without long introductions.
That said, those in search of a magic pill or craving universal formulas won’t find them here: this book is brutally honest and only works for those who are ready to hustle, make mistakes, and keep iterating until they win.
About the Author and His Impact on Marketing
Sean Ellis is one of the most well-known experts in growth and digital marketing. He coined the term “growth hacking” and was the first person to officially hold the title of "Growth Hacker" at Dropbox. He also helped grow companies like LogMeIn, Eventbrite, and Lookout.
Morgan Brown, the book’s co-author, is a hands-on digital marketer and product leader who has worked at Facebook, Shopify, and GrowthHackers.com. He strengthens the book by providing real-world cases and a systematic approach to business scaling.
The work of Ellis and Brown laid the foundation for the modern startup growth methodology. Their ideas helped many companies transition from chaotic marketing to structured experiments and sustainable growth. Today, their approach is used in both small startups and large tech giants.
The Book’s Place in Modern Marketing Literature
If you're searching among recently published marketing works for something that truly stands out on the shelf, this book inevitably catches the eye with its bold pragmatism and relentless directness.
Compared to the many monotonous retellings of classic ideas and dull theoretical collections, this book offers concrete data, real examples of mistakes, and clear instructions without unnecessary complexity.
Much of today’s marketing literature gets bogged down in clichés and repetition, but here you’ll find fresh air, specifics, and challenges that keep you on your toes.
The book offers more than just life hacks — it helps you rethink growth and customer engagement. Instead of theory, it provides practical solutions backed by real experience.
That’s why, in recent years, it has become something of a go-to reference among entrepreneurs and marketers who can’t afford to stand still and are hungry for real, measurable results, not just pretty promises.

Relevance of the Publication Today
At a time when the market feels like an overcrowded train station — with every other person rushing in with yet another “revolutionary” method — Ellis and Brown’s material arrives as a timely alarm bell in the here and now.
- The frantic pace of change, with new platforms rolling out almost quarterly.
- Hundreds of startups that rise and vanish before anyone can even remember their names.
- In this kind of atmosphere, where "yesterday" is already outdated and "tomorrow" arrives in a couple of hours, the book acts as an emergency support site.
This practical approach — where every piece of advice can be tested in your own business rather than just in cozy theory — becomes not just helpful but essential for survival.
The authorial style — no pomp, just respect for the reader’s intelligence — reinforces the confidence: this is not just another compilation, but a working tool that adapts to the moment.
For those still relying on outdated methods, this book might make it painfully clear how much time has been wasted on ineffective strategies.
Fundamental Marketing Concepts
At the heart of the narrative are not trendy buzzwords for their own sake, but deeply grounded fundamentals that the entire industry relies on:
- Understanding what the customer really needs — not through flashy presentations, but actual behavior.
- Daily engagement with feedback and endless micro-experiments.
- Recording every user action.
- Identifying bottlenecks in the sales funnel.
- Proper survey analysis — the key to success.
The authors lay bare why some brands scoop up the market cream in a matter of months, while others sink into oblivion. Readers may feel an uncomfortable jolt: even veteran marketers often lack a coherent data strategy, meaning they repeat the same rookie mistakes.
There’s no room for theories divorced from reality — only practical principles that can be implemented tomorrow, without waiting for a "Big Monday."
Innovative Ideas and Modern Trends
When it comes to new approaches and fresh trends, the authors don’t hide behind vague promises: they lay out real-life cases where ideas aren’t just claimed — they’re tested in the field every single day.
The book details with striking clarity how companies like Dropbox or Airbnb ran 50–60 micro-experiments each month — not for show, but to uncover that one insight that would disrupt the status quo.
The focus isn’t on trendy technologies, but on methods that help you stay afloat in an age when user preferences shift faster than your app can update.
- A/B testing new features
- Instant response to user pain points
Everything is delivered without sugarcoating, with clear respect for those who aren't afraid to fail but know how to pivot quickly. This sober approach to change — the ability to distinguish signal from noise — is what makes the book truly valuable: it doesn’t flatter your imagination, it gives you tools to ensure your business doesn’t stand still, but keeps pace with the new reality.
Applicability of Concepts in Modern Business
In today's corporate environment, where changes occur not by calendar but by market sentiment, the approaches discussed in the book are strikingly grounded and practical:
- The authors don’t try to pass off wishful thinking as reality, but offer tools that can be implemented here and now.
- Dropbox didn’t wait for favors from fate — it ran dozens of mini-experiments each month, and if we trust the numbers, it was this persistent hypothesis testing that helped them grow from 100,000 users to 4 million in just 15 months.
- Readers are shown not vague calls to “be innovative,” but a concrete way to organize idea generation — with daily team discussions and quick feedback implementation.
- The authors’ emphasis on the fact that modern consumers are unpredictable is disarmingly honest:
- No one promises lasting efficiency, but the book does offer mechanisms through which a business is forced to constantly test its assumptions.
- This approach is not just relevant — it’s vital in a world where yesterday’s algorithm is obsolete today, and only those ready to pivot quickly stay afloat while others fade into failure statistics.

Real Business Cases and Examples
When it comes to real-life illustrations, the authors don’t waste pages on fluff: readers are presented with specific stories where every figure, every outcome is the result of a live experiment, not armchair theorizing.
Take Uber, for example — it didn’t just “look for” its market but systematically tested hypotheses about user behavior in different cities:
- The company changed its pricing model weekly at launch,
- Monitored user reactions,
- And simply adapted to local habits on the fly.
These kinds of cases leave no room for illusions: achieving a real breakthrough isn’t about following trends — it means refining your processes daily and not being afraid to admit mistakes.
Diving into the book's material, it’s hard not to feel a bit annoyed at your past naivety: success, it turns out, isn’t about a brilliant idea — it’s about a thousand small tries.
And this is precisely what the authors emphasize, urging the reader to let go of the fantasy of a magic formula — instead, what’s offered here is a technological routine, tested not on lab rats, but on millions of users and real-world budgets.
Strengths of the Publication
What truly sets this work apart is its meticulous honesty in the details and its almost pedagogical persistence in teaching the craft:
The authors don’t lead readers into theoretical jungles, but rather guide them step by step through the maze of practical actions. — They mark the route with clear signposts in the form of tools, tables, and checklists. For readers used to ungrounded marketing promises, this kind of transparency feels like a cold shower. There are no golden keys handed out here, but real tools are given — ones you can implement as soon as tomorrow:- A/B testing processes described based on real platforms.
- Step-by-step guides for forming growth teams, drawn from Fortune 500 company experience.
- After reading it, you won’t be tempted to “just read for inspiration.”
- Your hand automatically reaches for your planner to reassess your processes and look for your next step.
Critical Analysis
But dig a little deeper, and it becomes clear: beneath the method’s apparent simplicity lie several contentious points that can’t be ignored.
- Small Business Constraints: In their enthusiasm for specifics, the authors seem to deliberately sidestep the harsh realities faced by small businesses — there’s no mention of how to implement their approach in companies with under 10 million rubles in turnover, a staff of three, and zero budget for experiments.
- Tool Universality: Despite claims of universal applicability, some tools feel copied from Western contexts: not every Russian entrepreneur can run “an experiment with 50,000 users” or assemble a cross-functional team à la Spotify.
- The Ideal World: A reflective reader can’t help but notice: behind every suggestion looms the shadow of a perfect world, where A/B tests go smoothly and clients happily take part in surveys.
Still, despite these rough edges, it’s hard to put the book down — even a skeptic will find a seed worth nurturing in their business processes, albeit with local adaptations and maybe a few strong words for the authors’ obsession with Western success stories.
Tools and Methodologies for Practical Use
In the practical part, the authors seem to scatter a wealth of tools and checklists before the reader, promising a quick start even for those who have just yesterday emerged from the accounting swamp into the marketing field. The pages feature idea prioritization tables, detailed instructions for launching experiments, as well as step-by-step feedback analysis schemes — all of this looks tempting and well-structured, if you don’t remember that outside the window is not Silicon Valley, but, say, the industrial outskirts of Yekaterinburg.
In reality, an entrepreneur with one marketer and three tasks for morning, day, and evening will most likely face the fact that implementing these methodologies requires not only enthusiasm but also time, which is chronically lacking. Especially questionable are the recommendations where the first step is to assemble a team of analytics, product, and design specialists, and the second step is to conduct a series of A/B tests across several user segments — as if talking about a large tech company rather than a family-run local store.
Nevertheless, some findings prompt the desire to immediately grab your favorite notebook and start experimenting — for example, concise templates for hypothesis recording or decision-making algorithms based on minimal data. Not everything offered can be implemented under limited resources, but the impulse to act these tools provide is a rare value amidst the abundance of watered-down advice found in other business books.
| Advantages | Disadvantages |
|---|---|
| Tools and checklists | Requires time and a team |
| Detailed instructions | Limited resources |
| Templates for hypothesis recording | Unrealistic expectations |

Comparison with Other Works by the Author
The book "Hacking Growth" differs from other publications by Sean Ellis and Morgan Brown (articles, blogs, interviews) in its structure and depth.
- There is no longer room for verbose reflections for their own sake.
- Every piece of advice, every method is calibrated as if by blueprint.
- Adapted to today’s realities.
- The customer has ceased to be an abstraction and has become the center of the universe for any business.
Unlike individual articles, the book offers a comprehensive strategy — from team formation to launching experiments. The book’s topics are explored in detail with real cases (Dropbox, Airbnb), rather than briefly as in blogs.
The authors’ style remains recognizable: ironic, slightly cheeky, intolerant of sloppy work — yet at the same time personal, like advice from someone who has stumbled and risen many times.

Similar Literature by Other Authors
Looking closely at the business literature shelf, it’s impossible not to notice how differently modern authors approach the topic of explosive company growth:
- Eric Ries in "The Lean Startup": emphasis on the philosophy of continuous hypothesis testing and cost minimization.
- Brian Balfour in his publications: structure and dry business-like tone, each chapter like an IKEA furniture assembly manual.
Compared to these works, the book in question wins due to its dynamics and depth of immersion in real scenarios:
- No attempts to hide behind buzzwords.
- Every page feels like an invitation to experiment.
- Even a modest startup investing $10,000 can claim a place in the sun.
James Clear focuses entirely on habits and long-term change, while Jeff Walker emphasizes launch fever and sales hype; here:
- Calm confidence and respect for data, not emotions.
This approach forces a critical look at the formulaic advice of other authors: it becomes clear that you cannot copy success using someone else’s template unless you break everything down and really understand the processes.
