DETGAAO

DETGAAO is a marketing consultancy founded by Michael Fellner, built on a single idea: marketing should connect to business results, not vanity metrics. Over two decades, Michael has managed $220M+ in digital P&L across D2C, B2C, and B2B brands including Frederick's of Hollywood, Zappos, Nasty Gal, and DanceOne, starting in finance (gross-profit analysis) before moving into eCommerce and digital marketing.

DETGAAO offers fractional CMO leadership, revenue architecture, performance marketing, channel strategy, and full-funnel execution for growth-stage brands in Switzerland, the EU, the US and Southeast Asia, from Zürich and Las Vegas. The model is deliberate: build marketing operations that run without us, then hand over the keys.
