Context

Organized crime impacts Brazil’s economy, but coverage was fragmented. The company saw an opportunity to create a dedicated editorial product supported by B2B sponsorship.

Readers

Readers needed a clear entry point to follow the topic and see value fast.

Sponsors

Sponsors needed a measurable product to reach a qualified audience.

Discovery

I analyzed the topic, target audience, and business opportunity to define how the content could attract readers, convert subscribers, and create value for sponsors.

12M+

Annual users created a strong top-of-funnel opportunity.

120K+

Active users on similar coverage showed proven demand.

25%

LP subscribers showed higher engagement than regular readers.

Growth Journey

Based on discovery, I structured the solution around three connected steps: attract, convert, and engage.

Content Hub

Support topic discovery and attract qualified readers.

Landing Page

Convert interested readers into newsletter subscribers.

Newsletter

Deliver recurring value and build engagement.

Wireframing

I used wireframes to define the structure of each touchpoint and align the experience around four key needs:

Editorial clarity

Make the topic easy to understand and navigate.

Clear value proposition

Show why readers should subscribe.

Low-friction conversion

Keep the path to signup simple and direct.

Sponsor visibility

Integrate sponsorship without disrupting the experience.

Content Hub

A dedicated editorial space to centralize the coverage, help readers explore the topic, and create a clear entry point into the newsletter journey.

Key Learnings

  • Connected journeys create stronger value: Building a clear journey across the Content Hub, Landing Page, and Newsletter made the experience more cohesive for readers and created a more structured product for sponsors.

  • Cross-platform measurement was the main challenge: Because each touchpoint lived in a different platform, connecting the full journey without losing measurement quality became one of the biggest challenges.

  • The product could evolve beyond sponsorship: A next step would be exploring a B2B subscription model for companies interested in deeper access to this coverage.
