Sean Ellis on Why Your Growth Team Is Probably Just Rebranded Marketing

Your Growth Team Probably Owns the Wrong Thing

Most companies that say they're doing growth are just doing marketing with a new title. Sean Ellis sees it everywhere outside Silicon Valley—and sometimes inside it too.

The pattern is predictable. A company reads Hacking Growth, buys thousands of copies for the team (Microsoft was one of the first), gets excited about the framework, then falls apart at execution. The reason? They carve out ownership instead of building influence.

I've seen where they start to say, well, I really believe in a model of ownership, and so this team owns this metric, this team owns this metric. And what that often leads to is the growth team owns acquisitions. So they'll replace a marketing team and just put a new name on it.

— Sean Ellis

The fix isn't better org charts. It's repositioning the growth team as a consulting force with execution chops—one that looks at the entire engine, uses the North Star metric as the guide, and steps in to help wherever the biggest opportunity lives. Not ownership. Influence backed by skill.

Dropbox Hit $1 Billion Faster Than Any SaaS Company For One Reason

Dropbox didn't compete in paid acquisition channels. Ellis and the team did essentially zero traditional marketing. No external ad spend. Just referral incentives and a growth engine that got stronger as the company got bigger.

The math is simple: when you're small, you can grow fast by adding channels. When you have 5 million customers, finding a new external source that moves the needle is nearly impossible. But if your growth engine is internal—driven by retention, engagement, referral—scale becomes your advantage, not your bottleneck.

In the case of Dropbox, the bigger we got, the bigger our growth engine got. And so we could grow and continue to grow at a very fast pace all the way through billion-dollar-plus revenue.

— Sean Ellis

Ellis believes this is why Dropbox reached $1 billion in revenue faster than any other SaaS company before it. The lesson isn't "don't do paid acquisition." It's that thinking holistically about conversion, engagement, monetization, and referral unlocks compounding growth that paid channels alone can't deliver.

The One Question That Fixes Cross-Functional Silos

Ellis has spent the last five or six years running workshops to solve the hardest part of growth: getting product, engineering, marketing, and data teams to actually work together. The breakthrough came from a single question at the start of every session.

"Why are you excited to be here?"

It sounds soft. It's not. The goal is to find the common thread. Product and marketing and engineering should all be excited about the same thing: customers who need the solution and the impact the company can make. Once they agree on that, Ellis moves to measurement.

It's a good concept, but a concept doesn't drive execution. Measurement drives execution. So how do we measure that? And that's when we get into a deep discussion on North Star Metric.

— Sean Ellis

When the team builds the North Star metric together, they care about it. And when they diagram the growth engine—new customers, existing customer frequency, monetization—they see how their work connects. Each metric is owned by a different team, but everyone influences the whole system. That's when cross-functional growth starts to work.

Growth Beyond Silicon Valley Faces a Different Problem

Ellis doesn't run into "think bigger" problems in Silicon Valley. Founders there are starting companies to change the world, backed by investors who've seen Apple and Uber scale. But in Europe and Latin America, he sees a different challenge: teams focus too much on incremental ROI and not enough on the size of the opportunity.

The irony? Silicon Valley has the opposite problem. Access to massive venture capital means efficient spending often gets ignored. Ellis believes the healthiest companies balance both: big thinking on impact, disciplined thinking on unit economics.

His fix in workshops is to start with impact. How many customers have this problem? How much are they suffering? Then: what metric captures our ability to solve that at scale? That conversation shifts teams from "what's my next acquisition channel" to "what breaks in our engine if we actually grow fast."

Usually the answer isn't another channel. It's retention. If you can just keep the customers coming in, growth accelerates. And retention improvements make every acquisition dollar work harder. The biggest opportunity shifts over time. Fix retention, and acquisition becomes easier. Fix monetization, and you unlock budget to invest everywhere else.

Why Ellis Keeps Taking Interim Growth Roles

Every six months to a year, Ellis steps out of teaching mode and takes a full-time interim growth role for three to six months. The goal is simple: stay sharp. Don't become an academic.

His most recent gig was with Bounce, a luggage storage network based in Lisbon. The company has physical partnerships and an app-driven customer experience—similar to Uber or Airbnb in complexity. Ellis believes they built Bounce into the fastest-growing company of its size in the world.

He also runs a program called Go Practice with a former Facebook data scientist, teaches skills, and is now launching a world tour. Starting in January, he'll spend a month in South America (Brazil, Argentina, Chile), then move through Turkey, Asia, Australia, and India. The mission: work with ecosystem partners in each country to help local teams approach growth in high-impact ways.

Ellis is clear-eyed about what he learns from these trips. Every conversation teaches him something new. Growth isn't solved. There's always a better way. And when people around the world use the scientific method in different markets, they figure things out at different paces. His job is to share what he knows and learn what they know. Everyone's skill set expands in the process.
