Marketing & Sales.

PhDr. Oliver Scharfenberg, MBA, is the founder and CEO of Syntharis Group in Dubai. He is a marketing and employer-branding expert with more than 20 years of experience in marketing and sales, a researcher on employer seals and the author of The AI Visibility Playbook.

His work connects three fields: how companies become visible in search engines and AI answers, how employers become attractive to qualified applicants, and how quality seals and certifications create credible trust.

He holds a doctorate (PhDr., Doctor of Philosophy), an MBA in Marketing from Middlesex University, a master’s degree in economics and a qualification as a Betriebswirt (business economist).

This academic background supports the research-based approach of Syntharis Group, particularly in employer branding and in the evaluation of seals and certifications.

The study analyzed more than 60 employer seals and tested their effect on applicants in a randomized experiment with 1,093 participants. The central result: a credible employer seal increased the stated likelihood of applying by around 16 percentage points.

The research also showed that credibility depends on the criteria behind a seal. Transparent and verifiable assessment methods matter more than the design of the logo. The study has been cited in the trade press and is indexed on Google Scholar and ResearchGate.

His books include The AI Visibility Playbook, a guide to SEO, Generative Engine Optimization and visibility in AI search, and the German-language Praxisleitfaden Mitarbeitergewinnung für kleine und mittelständische Unternehmen (2026), a practical guide to recruiting for small and medium-sized companies.

Both books are available as free downloads on the Syntharis Group website. He also publishes articles on marketing, employer branding and AI visibility.

His main areas are marketing strategy, employer branding and recruiting, AI visibility through SEO and GEO, quality seals and employer certification, and education consulting for universities.

He is particularly sought after where these fields overlap, for example when an employer wants to be visible to applicants in AI tools, or when a university wants to position its programs internationally.

Yes. He founded BERLIN International Studies and has supported doctoral programs, including the facilitation of PhDr. programs for working professionals. This experience with academic programs, admissions and the needs of international students informs Syntharis Group’s education consulting.

It also explains why the firm runs its own student-recruitment landing pages, such as phdr-studium.de and doctoral-degree.com.
