Having been writing about growth hacking since 2014, we dare to say that we are one of the oldest growth hacking blogs in the marketing world. We are known to practice first and then preach. Through our blog, we share everything that we believe can work for you because, first and foremost, it has worked for us and our clients.
Among GrowthRocks’ articles, you will find tips, tricks, frameworks, and knowledge for all digital marketing branches, including SEO, conversion marketing, and product marketing. Also, you will be introduced to many growth hacking tools.
CXL is one of the best places to learn more about data-driven marketing, conversion optimization, and analytics. This is where you will get conversion and marketing advice based on scientific research and in-depth industry knowledge.
Ultimately, the purpose of this growth hacking blog is to teach you how to turn more visitors into customers.
Besides CRO, CXL specializes in these categories: User Experience, Business Growth, Online Courses, eLearning, Data-driven Marketing, Online Training, UX, landing page optimization, product messaging, sales page copywriting, saas growth, and SEO.
Reforge offers selective growth-focused programs for experienced professionals in marketing, product, data, and engineering. All programs are led by actual growth practitioners Brian Balfour (formerly VP of Growth @ HubSpot) and Andrew Chen (Growth @ Uber).
Among the pages of Reforge’s blog, you will find insight from top growth hackers and leaders. Many of them have worked for companies like Google, Slack Dropbox, LinkedIn, Atlassian, and Pinterest.
Some of the most popular content pieces of this growth hacking blog include “12 Data Science Guidelines for A/B Testing”, “The 4 Different Types of Product Prototypes”, and “The Product Strategy Stack”.
No list of the top growth hacking blogs would be complete without Sean Ellis’s blog. Naturally, the person who coined the term “growth hacking” and helped companies like Dropbox, Eventbrite, and LogMeIn achieve breakout growth has his own blog.
Through his Substack, Sean shares deep insights, case studies, and practical frameworks for startup growth, covering topics like activation, retention, and experimentation. Whether you’re a founder, marketer, or product leader, his content helps you apply high-impact growth strategies used by the world’s fastest-growing companies.
Some of his standout posts include: “The Growth Hacking Mindset: How to Think Like a Growth Leader” “Why Most Startups Struggle with Retention (And How to Fix It)”, and “The Dropbox Growth Engine: A Deep Dive”.
I didn’t know about Growth Design’s existence until recently and I’m so happy that I did. In s sentence, Growth Design offers product tips and insights in a comic book format. Right now, the Growth Design site features 64 UX case studies to improve your product skills.
These case studies put a spotlight on companies from the big tech as well as smaller tech companies. They are broken down into 3 basic categories: Onboarding, Retention, Revenue
What’s more, on the site you will find a section with ‘100 Cognitive Biases & Principles That Affect Your UX’. From The Spotlight Effect to Hicks’s Law, you will learn some of the basic biases and heuristics of human psychology that affect the user experience. And the smart growth hacker will have to either avoid them or capitalize on them.
If you are not entirely new in the marketing industry, you already know Noah Kagan, and his blog – OkDork. Before founding sumo.com and appsumo.com, Noah was #30 at Facebook and #4 at Mint. Since then, he’s come a long way and OkDork’s blog is one of the fruits of his (intense) labor.
Through this blog, Noah explores actionable tips and tactics on marketing, starting a business, personal improvement, and productivity.
According to Noah, some of his best articles are ‘Why I Walked Out on Tony Robbin“, “Peek Inside Intercom’s Multi-million Dollar SaaS Growth Strategy”, and “What I Learned Growing an 8-Figure Business”.
Lenny Rachitsky is interested in three things: product, growth, and startup building. Accordingly, he is more than happy to share much of his knowledge with anyone who is also interested in these three things. But who is Lenny?
Lenny Rachitsky is a product specialist who spent many years working at Airbnb as a product manager before working up to product lead for supply growth. Nowadays, he is an investor, a product consultant, and a writer.
In the newsletter list of his more than 700,000 (!) subscribers you will find a few high-profile subscribers from the tech world such as Ryan Hoover, Andrew Chen, Li Jin, Bri Kimmel, and Jeff Chang.
Hubspot’s VP of marketing, Matthew Barby loves talking about leadership, growth, community, and blockchain/web3. He also loves writing and expanding on these topics and he does so through his blog.
What’s more, Matthew is an advisor to a number of startups and large SaaS businesses, an investor, a lecturer, and a global speaker.
Here are some of his latest articles: ‘You Can’t Buy Product-Market Fit’, ‘CBDCs: A Wolf in Sheep’s Clothing’, and ‘From Bootstrap to Buyout: How We Sold Our Side Hustle to a Public Company’. Matthew’s last publication was in early 2024 and we still don’t know if this was also his last one from his personal blog.
A popular community for product-led growth professionals, ProductLed’s ultimate mission is to make you great at product-led growth.
Through the blog’s basic categories Product-Led Growth, Customer Acquisition, Customer Activation, Product Monetization, and Product-Led Strategy, you will learn how to grow and build a successful product-led business.

Tomasz was the product manager for Google’s AdSense social media products and AdSense internationalization. He is also the co-author of Winning with Data and a growth/ tech blogger, which is why he’s on this very list.
Some of the most notable blog categories from Tomasz’s blog include Crypto, Fundraising, Content Marketing, and Recruiting.
To get a glimpse of the kind of read in Tomas’z blog, these are the three latest published articles, in early 2025: ‘The AI Cost Curve Just Collapsed Again‘, ‘Top Themes in Data in 2025‘, and ‘Top Themes in Data Transcript‘.
