Lin Zeri, advertising professional and founder of Etuos
Nice to meet you, I'm Lin
I'm an advertising professional specialized in digital marketing, and I started down this road more than 10 years ago. I worked at results-driven agencies, where I managed $500K+ in ad spend and learned, hands on, what separates a campaign that sells from a campaign that just spends.
Along the way, I collected cases I'm proud of. The biggest one: helping a solar energy network grow from 30 to 300+ franchises in 1 year and 8 months, with digital marketing as the engine behind the expansion. For other clients, revenue grew more than 300% with ads and website working together.
I founded Etuos in 2023, at first serving clients in Brazil and a single client in the United States. That client opened my eyes: small business owners in the US work hard, deliver quality service and almost never have marketing that matches it. Since then, the American market has become the center of my work, and today Etuos is a digital marketing agency for businesses in the United States.
I live in Brazil and run US accounts every day, on US hours, in English and Spanish. I know how the American customer searches and decides, whether that customer is American-born, Hispanic or Brazilian. And the person answering your WhatsApp is me, not a support rep.

What I believe in
Honest marketing gets better results
Honesty before the contract
I'd rather lose a client by telling the truth than win one by misleading them. If your business isn't ready for the service, I'll say so in the diagnosis.
Best practices for everyone
The small client gets the same standard of work as the big one. Method is method, and it's the same one I've used for a decade.
No miracle promises
The market is full of people selling cheap leads and guaranteed results. Here the conversation is different: realistic goals, serious work and numbers measured every month.
