Finnex Agency

We turn clicks into profitable customers

We do not chase customers. We make them want to buy.

Mission, vision and values

What we believe

Mission

To give every brand the clarity it does not have today: knowing exactly what is generating its margin, what is draining it, and in what order to fix it.

Vision

That growing on Amazon stops being a gamble and becomes a business decision, held to the same discipline as any other line of the company.

Values

Transparency

Data before promises. We do not promise results without first seeing where you stand, and every decision we make on your account is backed by numbers. If something does not add up, we tell you.

Profitable growth

Growing sales is easy if cost does not matter. We optimize so the money you put into Amazon comes back with margin: real profitability, not vanity metrics like traffic or ROAS.

Long-term vision

Amazon rewards consistency, not shortcuts. Positioning and sustained profitability are built with method and discipline, not overnight. We work with brands that think long term.

Our story

How it all began

The origin
It started by weighing up our own brand
Finnex did not come from outside the business. It started when we were weighing up launching our own brand on Amazon: we studied the marketplace in depth, the advertising, the listings and the variables that decide whether a brand grows profitably. Then we launched, with our own capital at stake and the same pressure on margin, inventory and competition any brand faces.
The learning
We lived the problems we now solve
We went through what we now see in so many accounts: ad spend that burned budget with no return, content that drew visits but did not convert and decisions made on intuition instead of data. Every mistake cost us our own money, which is exactly why we know where to look today.
The method
We turned experience into method
Over time we stopped improvising and systematized what actually worked. We combine engineering, design and data analysis into a repeatable method we apply to every account, so growth does not depend on luck but on a process.
Finnex today
A partner to grow profitably
Today we work with brands that want to build a solid business on Amazon, not a passing spike. We bring professional standards, a focus on profitability and a long-term view on every decision.

Founders

We come from design and from engineering

Two crafts almost no Amazon agency combines, and they decide whether an account makes or loses money: whether the shopper clicks and buys, and whether the spend comes back.

Federico Mansilla

Co-Founder

Cloud infrastructure engineer. Six years as a DevOps for US startups, optimizing systems and cutting operating costs on AWS. He applies that same efficiency logic to campaign architecture and to automating the operation. If a number does not add up in your account, he will find it.

Florencia Rios

Co-Founder

Multimedia design technician, certified in user experience. She knows what makes a listing read as a buying opportunity rather than just another product: visual hierarchy, imagery, A+ content and what the shopper decides in the first few seconds.
