We help businesses become visible where customers increasingly make decisions: AI.

Dennis has spent more than two decades helping businesses grow through technology, digital marketing and ecommerce.

His career spans consulting, entrepreneurship, SaaS and executive leadership, giving him experience across almost every stage of the digital customer journey, from enterprise technology through to international ecommerce organisations.

His expertise covers technical infrastructure, SEO, content strategy, performance marketing, influencer marketing, social commerce and AI-supported marketing.

As Co-founder and CEO of Fourstarzz Media, Dennis built an international influencer marketing agency and SaaS platform that helped businesses scale influencer marketing globally. The platform was later included in Gartner's Marketing Technology Vendor Guide.

Since 2018, Dennis has been a member of the Forbes Agency Council, where he has written about digital marketing, SEO, social commerce, influencer marketing and the business impact of emerging technologies.

Most recently, as President North America at Spread Group, he led the company's North American business and its ecommerce, marketing and growth strategy.

Earlier in his career, as Operations Director DACH and EMEA at Groupon, he led international teams during one of the fastest periods of growth in the digital economy.

Dennis began his career at Accenture, where for more than a decade he delivered international transformation, systems integration and digital transformation programmes for leading organisations in telecommunications, media, technology and aviation.

Today he combines that experience with Generative Engine Optimization (GEO), helping businesses become not only discoverable, but also recognised and cited as trusted sources by AI systems including ChatGPT, Gemini, Claude and Perplexity.

For more than 15 years, Thomas has focused on one question: how do businesses remain visible as digital markets evolve?

His background combines ecommerce, performance marketing, partnerships, brand strategy and business development.

Following leadership roles at Spread Group, Thomas advised businesses, agencies, creators and artists on brand positioning, audience growth and sustainable monetisation strategies.

Today his work focuses on the next stage of digital visibility: helping businesses remain relevant as more people rely on AI systems rather than traditional search engines.

Thomas combines strategic marketing thinking with practical experience of building brands, partnerships and digital business models. He challenges assumptions, cuts through industry hype and helps organisations understand what technological change means in practice.

As Co-founder and CMO of auffindbar.ai, he helps businesses structure and communicate their expertise so that both people and AI systems recognise it as credible, relevant and worth citing.

Thomas also mentors startups in marketing and business model development at SpinLab – The HHL Accelerator Leipzig and hosts his interview series, Business with a Smile, featuring leaders from the marketing and media industries.
