#18 | From Dropbox to Eventbrite: The Billion-Dollar Growth Playbook for 2025

How Sean Ellis’s timeless growth principles—and new AI strategies—are reshaping startup success.

Welcome to GTM Vault, where 20,000+ founders and revenue leaders decode the playbooks behind B2B’s fastest-growing companies.

This week: Sean Ellis—the OG growth hacker behind Dropbox, Eventbrite, and LogMeIn—reveals why most founders stall out (and what’s different in the AI era).


🔦 This Week’s Spotlight

Sean Ellis (author of Hacking Growth, creator of GoPractice.io, early growth leader at multiple unicorns) on what really drives breakout growth:

→ 🎯 The Dropbox Secret: Growth started before the referral program — natural virality + relentless onboarding optimization.

→ 🛠️ Freemium That Doesn’t Suck: Why LogMeIn re-architected before they could afford to offer anything free.

→ 🤖 AI’s Real Role: Faster testing, sharper onboarding — but fundamentals (PMF + retention) still reign supreme.

→ 🚀 Growth Culture: Build teams that love failing fast — and treat version 1 of anything as a test.

→ 📈 Activation > Acquisition: Most companies chase paid ads too early. Fix activation first — or churn will kill you later.


🎯 5 Tactical Takeaways (Steal These)

1️⃣ Product-Market Fit or Bust 🎯
"No PMF, no growth engine. Period. AI won’t save you if the product sucks."

2️⃣ Activation Is Everything 🚪
Long-term retention (and growth) is decided in the first moments. Onboarding isn’t just UX — it’s survival.

3️⃣ Focus on Superfans 🦸‍♂️
Use the "Must-Have Survey": Double down on users who’d be very disappointed if you disappeared. Forget the lukewarm.

4️⃣ Freemium Needs Economics 📉
Don’t offer free until your unit costs support it. (LogMeIn’s server re-architecture dropped bandwidth costs by 95% — then they launched freemium.)

5️⃣ Founders Must Own Growth 🧠
Growth isn’t a department. It’s a cross-functional system. Founders who scale (like Drew Houston) own growth as a system, not just a goal.
