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 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 Zurich and Las Vegas. The model is deliberate: build marketing operations that run without us, then hand over the keys.
