A performance lab for brands scaling in Brazil and abroad.
We are a Brazilian team of paid media, creative and analytics operators. We work fully remote and serve brands in Brazil, the United States, Canada and the United Kingdom — in Portuguese and English, with no middle layer.
Where we operate today
Small numbers, big decisions.
We are a new operation by choice: a lean team, few accounts at a time, and decisions driven by data — not opinion.
A lab, not a traditional agency.
Mevak Lab Marketing LTDA was incorporated in December 2025, in São Paulo, to operate as a growth lab — not a bloated retainer agency. We brought together people who came from inside digital-native brands in Brazil and abroad, and built a small, technical, bilingual structure.
We believe good work happens when whoever executes is close to the account. So we don't have layered hierarchy: the person running your media is the one talking to you — and it's the same person who made the creative test work.
“We'd rather run a few accounts in depth than list a long row of logos on the website. Performance marketing doesn't scale on attention — it scales on focus.”— Mevak Lab internal principle
Three things we don't compromise on.
Data-driven decisions, not opinion
Every campaign, creative or page change goes through a data read. If it can't be measured, it doesn't count.
Bilingual team, no middle layer
The person speaking with the American or British client is the same one running the account. No translation-by-manager.
Test fast, decide without drama
Short test cycles, written hypothesis before launching a creative, and clean cuts when the numbers say cut.
Mevak Lab services.
Each area below can be hired standalone or as an integrated package. Our sweet spot is running media + creative + analytics together, but we work with whatever scope makes sense for your moment.
Paid media management
Google Ads, Meta Ads, TikTok Ads and YouTube. Structure, budgeting, creative and daily optimization, with weekly reports in Portuguese or English.
Growth analytics and attribution
Tracking setup, GA4, server-side events, multi-touch attribution and LTV reading. You stop arguing with Meta about which sale came from which campaign.
Creative studio
Statics, short-form video and VSL production for paid media. Scripting, editing and versions in Portuguese and English, built for each channel's algorithm.
Conversion and landing page optimization
Funnel analysis, heatmaps, landing page redesign and A/B tests with hypothesis before launch. The goal is lifting conversion, not just prettier design.
International expansion (US · CA · UK)
For Brazilian brands entering the United States, Canada or the United Kingdom: account structure, creative adaptation, payment and tracking in English.
Acquisition and scale consulting
A short engagement (4 to 8 weeks) for brands already running media internally, who need a seasoned second pair of eyes to unblock CAC or prepare for scale.
Clients who've been through the lab.
“The way they read data is different. In two weeks we found out that half our conversion was coming from an audience we had accidentally turned off three months earlier.”
“We hired Mevak Lab to run our US paid social. What sold us was the bilingual team — no lost-in-translation calls, no time zone excuses. Numbers moved in the first month.”
“Straight-talking, no fluff. They pushed back on ideas we thought were sacred and were right about most of them. That's rare.”
Tell us what you're trying to solve.
Every proposal starts with a 30-minute conversation, at no cost. If it makes sense on both sides, we move to a diagnosis. If not, we'll point you to someone better suited to the moment — we prefer it that way.
