Who leads
Quality SMI
Matheus Silveira
CEO AND FOUNDERMatheus started as an entrepreneur at a very young age. Closely following Google's growth throughout the 2010s, he spotted an opportunity the traditional market hadn't yet noticed: while conventional advertising remained almost exclusive territory for big brands, digital marketing opened the door for any company to grow with tailored, measurable, and scalable investments.
It was with this vision that he founded Quality SMI, an agency built on a simple principle: technique must serve the business. In more than a decade leading the company, he developed a specialty in International SEO and became a reference in GEO, the practice of positioning brands not just at the top of Google, but as the primary answer given by the new generation of artificial intelligence.
Today, Matheus leads a team of more than 30 professionals and stays directly involved with the SEO, content, design, and technology teams, making sure every strategy delivered is technically solid and driven by real results.
