ROI Digital Launch: A New Chapter for Adrian Stitzel
After five years at the agency Building Brands, digital marketing expert Adrian Stitzel is taking the next step: In June 2025, he founded ROI Digital GmbH, based in Zurich. With the founding of ROI Digital, Stitzel is building his own digital marketing company—and, true to the company’s name, is consistently focused on measurable results.
A Track Record of Successful Partnerships
Stitzel has enjoyed the trust of his existing clientele from the very beginning: AMAG Automobil und Motoren, the retail chain Denner, and Gerstl Weinselektionen are supporting him on this new journey. These three established companies are continuing their partnership with Stitzel and will now be supported by ROI Digital in all areas of digital marketing—from strategy and performance marketing to social media marketing.
Focus on Impact and Return on Investment
ROI Digital stands for a consistently results-driven approach to digital marketing. «Our name says it all,» says Stitzel. «Every initiative must pay off—for our clients and for their success. With ROI Digital, I’m creating a structure that embodies and scales this commitment.»
According to the agency, the service portfolio of the new Zurich-based agency includes performance marketing, SEO/SEA, social media marketing, programmatic advertising, and data-driven campaign management.
