About

I'm Sean Ellis, currently serving as Fractional VP Growth at Friction Free Dental and the author of 'Hacking Growth.' My career has been defined by helping startups bridge the gap between having a great product and building a repeatable growth engine. I’ve had the privilege of leading growth at companies like Dropbox, LogMeIn, and Eventbrite, and founding platforms like GrowthHackers. I’m deeply passionate about the mechanics of Product-Market Fit and the 'Aha moment' that turns users into lifelong advocates. Currently, I’m spending a lot of time experimenting with AI systems and Answer Engine Optimization to understand how they are reshaping the growth landscape. I love connecting with founders who have early traction and are ready to design durable systems for scale.

Opinions

Competitive advantage is found in 'non-obvious truths' where AI is wrong.
In early growth, the goal is reducing uncertainty, not efficiency.
Product-Market Fit must be continuously revalidated, not just a one-time milestone.
Customer advocacy is the only durable moat in the AI era.
Hidden price increases destroy trust in an era of perfect information.
