Growth Hacking Starts Here: Interview with Sean Ellis

Sean Ellis coined the term "growth hacking" and has been instrumental in shaping the discipline as we know it today. As the founder of GrowthHackers.com and the author of "Hacking Growth," Ellis has worked with companies like Dropbox, Eventbrite, and LogMeIn to build growth systems that deliver outsized results. In this interview, he shares his perspective on where growth hacking started, how it has evolved, and where it is heading.

The Origin of Growth Hacking

Ellis explains that growth hacking emerged from a simple observation: startups needed a different approach to growth than what traditional marketing offered. They did not have large budgets or established brand recognition. What they did have was a product, data, and the ability to move fast. Growth hacking was born from the need to find creative, scalable, and measurable ways to grow with limited resources.

The term itself came from a practical need. When Ellis was looking to hire someone to lead growth at a startup, traditional marketer job postings attracted candidates with brand marketing backgrounds who were not suited for the role. He needed someone whose primary focus and skill set was centered entirely on growth. The term "growth hacker" attracted the right type of candidate: someone who combined analytical thinking, creative problem-solving, and technical fluency with a singular focus on growing the business.

Key Principles Ellis Emphasizes

• Product-market fit comes first. No amount of growth hacking can save a product that people do not want. Before investing in growth, validate that your product delivers genuine value to a definable audience. Ellis recommends his "must-have score" survey: ask users how they would feel if they could no longer use the product. If at least 40% say they would be "very disappointed," you have product-market fit.
• Focus on the "aha moment," the point where users first experience the core value of your product, and work to get more users to that moment faster. The faster users reach the "aha moment," the more likely they are to become engaged, retained customers.
• Build experimentation into the company's DNA, not just into the marketing team. Growth is a cross-functional discipline that benefits from contributions across the entire organization.
• Growth is a team sport. The most successful growth programs involve collaboration across marketing, product, engineering, and data teams. No single person can drive sustainable growth alone.
• Focus on learning velocity. The team that runs the most experiments and learns the fastest wins, even if many individual experiments fail.

The Evolution of Growth Hacking

Ellis notes that growth hacking has matured significantly since its early days. Today, structured frameworks like the growth process help organizations apply these principles systematically. What started as a collection of tactics used by scrappy startups has evolved into a structured discipline with established frameworks, dedicated tools, and recognized career paths. Today, growth teams exist at companies of all sizes, from five-person startups to Fortune 500 enterprises.

The core principles, however, have not changed. The emphasis on experimentation, data-driven decision making, cross-functional collaboration, and relentless customer focus remains as relevant today as it was when the term was first coined.

Looking Ahead

Ellis sees growth hacking continuing to evolve as AI and automation tools make experimentation faster and more accessible. He emphasizes that while tools change, the fundamental principles remain the same: understand your customer, test relentlessly, measure rigorously, and let the data guide your decisions. Companies that embed these principles into their culture will continue to outgrow their competitors regardless of what the next wave of technology brings.
