Who isWill Jardim
Content and branding strategist with 17 years lived inside the fitness market. Not watching from the sidelines: living off it.
17 years on the inside
From the first video to a marketing director role: a whole career living off the fitness market, not watching it from outside.
William Jardim, Will, started out filming videos on a camera that overheated every 5 minutes and went on to run marketing for one of the fastest-growing supplement brands in Brazil. In between: 17 years in the market, always on the inside.
Today he's the official Mercado Livre consultant, part of the platinum consultancy, the largest fitness and supplements consultancy on the platform in Brazil. He works with brands and professionals who need to turn real competence into market perception.
The method
It starts from a simple observation: plenty of people have the know-how, the credentials and the results, but nobody knows it. The work brings both sides together.
Earned authority
What you've already achieved: years of practice, credentials, clients served, provable results. It exists, but it doesn't show.
Perceived authority
How much the market knows about it. Without built perception, competence stays invisible and the client picks whoever shows up.
The tool is strategic content driven by the audience's vital pain point: not the process, but what's behind it. Nobody buys weight loss: they buy the new relationship, the beach, the confidence. That's the difference between generic content and content that sells.
And one non-negotiable rule runs through everything: nothing here is a fabricated story. It's a career organized and made visible, backed by public sources and verifiable results.
We help companies stop competing on price and start competing on preference.
Prove it,
don't invent it
Education
The guy who walked away from a heavyweight academic career to live off what actually delivers results.
Veterinary Medicine
Federal University of Uberlândia (UFU)
One of the most competitive veterinary programs in Brazil, with 27 applicants per spot, at the country's 18th-ranked university (RUF/Folha).
Master's in Animal Reproduction
UNESP Jaboticabal (FCAV)
A CAPES-rated 6 program: international-level excellence in Brazil's graduate program evaluation.
MBA in Controllership and Finance
FIPECAFI/FEA-USP
The accounting and finance school tied to FEA-USP, a benchmark for training people who decide with numbers.
Will had the security of a solid academic career ahead of him, and he walked away from it after realizing, still in college, that path wouldn't deliver the return he was after. He chose the market. But the education didn't get left behind: it's exactly why the method combines science (a master's-level rigor) with numbers (a finance mindset), instead of just talking a good game.
Values
Discipline, merit, and things spelled out in black and white.
Will has an openly declared fascination with the military world. Not with war, but with what it represents: hierarchy, discipline, meritocracy, clear rules, everyone in their lane.
A Christian, he sees his own work as an extension of what he believes: nobody should stay invisible just because they don't know how to tell their own story. From the athlete to the supplement brand, from the aesthetics clinic to the clinical analysis lab.
Conduct, in numbers
- 15years of ongoing partnership with the same athlete
- 4years (almost) leading marketing at the same company
- 1compensation model: tied to the success he himself generates

Other people talking about the work, with public sources.

Frequently asked questions
What is Will Jardim's track record?
17 years inside the fitness market: from the first video recorded on a home camera to leading marketing at Under Labz, where a full rebrand earned 14+ features on the international portal Stack3D.
What is acquired vs perceived authority?
It is the core of the method: acquired authority is real competence (training, experience, results); perceived authority is how much the market sees it. Will's work closes the gap between the two with strategic content.
What results back the method?
Cases measured by verifiable results with success-based upside, including a 15-year partnership with Fernando Sardinha, 3x bodybuilding world champion with 98 titles accumulated since 1989.
