Mariana Mancini Content Strategy · 360° Marketing Direction · Go-to-Market Operations · Digital Operations

Less "what's today's post".
More marketing fundamentals.

A strategist's biggest contribution isn't posting content, it's the marketing that comes before it. I'm Mariana Mancini, with a degree in Business Administration (Marketing emphasis), dedicated to brand strategy and direction. I work across strategy, content and operations for businesses looking for a genuine presence and real results.

Perception can't be bought.

It's built.
360° Marketing

What I actually do

I understand every front of marketing, online and offline. To me, brand strategy starts before the phone screen, the way it always used to.

01

Launch strategy

Go-to-market planning, day-by-day calendars and tracking metrics for new products entering the market.

02

Strategic copywriting

Captions, scripts and hooks written to retain and convert. The best-performing viral posts on my accounts were my own copy, not just management.

03

Operations management

Running multiple clients in parallel without losing brand identity. Calendars, approvals, workflow with designers and video editors.

04

Reporting & performance

Monthly metrics, data analysis and strategic recommendations to guide content decisions.

The problem

ISN'T CONTENT. ISN'T TRAFFIC. ISN'T THE ALGORITHM.
The problem is the gap between expectation and reality.
Track record

Selected projects

Every project gets its own strategy, not a ready-made formula. I lead strategy, direction, people management and execution.

01

B2B Platform · Private Sector

Technology · Launch · Under NDA

Go-to-market strategy, day-by-day editorial calendar, copy for 20+ Reels per phase, channel structure and launch metrics.

02

Digital product, mentorship for Brazilians in the US

Under NDA · Brazil/US · 71.9K followers

Organic funnel, launch copy, stories sequences and editorial line for an evergreen product. Two lifestyle videos broke the account's average: 158K and 103K views, far beyond the follower base.

03

Women's mentorship program

Under NDA · Enrollment opening · Institutional voice

Audience warm-up, enrollment opening and engagement for a mentorship program, with no direct selling in the feed.

04

Profiles built from the ground up

Under NDA · Accounting Brazil/US · Two distinct niches

Briefing, ICP, editorial line, calendar and full copy for two profiles built from scratch, with no overlap in positioning. Something I've done many times, behind the operation and online: building from zero.

Proof of range

Different niches, same strategy

Language and goals change with each business. The method behind them doesn't.

Entrepreneurship & Mindset · Brazil/US

Lifestyle and achievement

Aspirational content about the lives of Brazilian entrepreneurs in the US, focused on relatability and organic reach.

Aesthetic uniforms · US

Bilingual e-commerce

Bilingual content for beauty and healthcare professionals. Collection launches, carousels and emotional Reels, focused on conversion.

19.2K followers
Cardiology · Dr. Maurício Prudente

Warm and technical tone

"Getting a routine exam and finding out your heart needs a deeper investigation can bring fear and uncertainty, especially far from major medical centers."

Real estate · Auctions

Direct and provocative tone

"While some people crash trying to 'go it alone', we're buying properties at 50% OFF. Really? The video is a meme, but the method is science."

Legal education · Escola Brasileira (EBATS)

Technical and provocative tone

"Have you ever wondered why so many brilliant lawyers freeze when a case reaches the Supreme Court? The answer is simple: arguing before the Court takes knowledge that goes far beyond theory. And that isn't something you learn in law school."

Current role

From social media to marketing director

I currently work as a 360° Marketing Analyst (online and offline) at PsiuClass, a platform that connects teachers and students with in-app payments, in a marketplace model (like Uber for classes), where I also serve as volunteer Marketing Director.

I built the brand manual, the audience map and the design curation from day one, led the startup's launch and structured the online and offline strategy, the brand voice and the full editorial line. I make hiring decisions for the digital marketing and sales team, and I take part in curating the products on the platform.

The offline front has already led to conversations and partnerships with Microsoft, Google and participation in Santander's startup campaign.
