Über mich

I build and scale marketing and e-commerce for consumer brands. Over the past 20 years I have led marketing, performance and digital commerce at companies like Petromax, Sennheiser, Amazon and Clark, with media budgets of up to €60m and teams of up to 15 people.

My sweet spot is the combination of leadership and hands-on depth: I set the strategy, and I still know the ad accounts, the tracking setup and the shop backend behind it.

Core areas:

? Omnichannel Marketing & Brand: As Head of Marketing at Petromax I was responsible for the full omnichannel business across D2C, Amazon and retail, including a brand identity and packaging refresh rolled out to more than 1,000 retail touchpoints and a national brand ambassador campaign.

? Performance Marketing & Media: Meta, Google and TikTok at scale. CAC, ROAS and LTV steering, forecasting, budget allocation and full-funnel attribution. +35% ROAS within one campaign cycle at Amazon, +37% CAGR in global digital revenue at Sennheiser.

? D2C & E-Commerce: At Petromax I built a two-brand D2C business end to end: Shopify Plus replatforming, WMS and logistics integration, PIM and DAM, tracking and CRM. D2C revenue grew roughly 15x in three years.

? AI-Enabled Marketing: Driving member of a company-wide Core AI team (governance, training, tool selection). Built an AI-based creative setup with product-level personalization for Meta and Amazon.

? Leadership & Stakeholder Management: Built and coached cross-functional teams of up to 15 people, reporting to CEO, executive board and supervisory board, with a dotted line to the Co-CEOs at Sennheiser.

Based in the Hanover region. My role at Petromax was eliminated in a restructuring in August 2026, and I'm now open to my next leadership role in marketing or digital commerce at a consumer brand. Hamburg and remote-first setups are welcome.

Always happy to exchange ideas on e-commerce, performance marketing and AI in marketing.
