About

We're an agency built for clinical laboratories.

More than 200 labs served across Brazil.

In 2017 we took on our first clinical laboratory. Two years later we made the decision that set the agency's course: concentrate team, method, product, and study on a single sector.

How we got here

From generalist agency to a marketing and technology ecosystem for clinical labs.

2017
The first lab
Sommer Publicidade started as a generalist agency doing a bit of everything: print collateral, brand and website design, social media. That year it took on its first clinical laboratory.
2019
The decision to specialize
After two years serving labs alongside other industries, the advantage was obvious: being known as the specialist in a sector with thousands of labs and almost no agency dedicated to it. That's when Sommer Publicidade e Eventos LTDA was incorporated.
2020
Growth through the pandemic
The pandemic arrived right after, coincidence, not planning: the sector became the center of attention across Brazil and had to communicate like never before. That same year we built our first online storefront for a client, where patients bought COVID-19 tests online.
2021
Clube do Lab is born
The project came out of a problem that kept repeating: owners of small labs knew they had to be on social media and had no team, no budget, and no material. Launched as an MVP in July, delivered by hand through Google Drive in a WhatsApp group.
2024
From service to SaaS
A software house built the Clube do Lab platform. What had been a Google Drive folder and manual delivery became a Software as a Service.
2025
Technology moves in-house
Software development was brought in-house. From 2025 Sommer also operates in technology, building its own products, and stopped depending on an outside vendor to evolve Clube do Lab. That same year we started designing Leevy, the online storefront technology for labs.
2026
Leevy
Launched in April 2026, it's the online storefront technology for clinical labs. With it, the loop we spent years watching stay open finally closes: the lab spent on marketing with no way to know how much of it became a paid test.

Ecosystem

The agency moved into technology as well.

Two proprietary platforms. One for marketing, one for sales.

Our marketing platform for clinical laboratories. Clube delivers ready-to-publish content, landing pages, AI, and a CRM in one place, on a subscription.

clubelab.com

Our online storefront for clinical labs, built for self-pay and direct-access testing. The patient picks the test, books, and pays online, without calling the lab or standing at the front desk. The last step of the funnel, solved in software: where the campaign ends, the sale happens.
