Jock Breitwieser – Founder and Chief Marketing Strategist, SocialSellinator

Jock Breitwieser is the founder of SocialSellinator, a B2B digital marketing agency headquartered in San Jose, California. He started the agency in 2017 after two decades of corporate marketing and communications work at technology companies across Silicon Valley. Today, SocialSellinator serves SMB and mid-market companies – mostly in B2B tech, professional services, legal, and real estate – with SEO, paid media, content marketing, LinkedIn campaigns, website conversion, and AI search visibility.

Before SocialSellinator, Jock held senior marketing and communications roles at Arcserve (VP, Global MarCom and Brand), TriNet (Corporate Communications, through the company’s IPO), Dell SonicWALL (Director, Global Public Relations, through the Thoma Bravo privatization and Dell acquisition), CallidusCloud, and agency-side at Edelman, Havas, and The Hoffman Agency. That background matters in practice: Jock has run the playbook from inside high-growth companies and from the agency seat, which shapes how he approaches client work today.

He is also CMO and board member of the German American Business Association (GABA) Northern California, and serves as a partner with Advantage Austria, supporting European companies – particularly from the DACH region – that are entering the U.S. market. He lectures on marketing and social media at UC Berkeley Extension and San Jose State University, and is a named Top 100 Social Selling Influencer. His work and commentary have appeared in Grit Daily, Marketer Magazine, DevX, Euro News, Hootsuite, Under30CEO, and other outlets.

Outside of work, Jock is a competitive triathlete. He has qualified for Age Group Team USA in Aquathlon and will represent the United States at the 2026 World Triathlon Multisport Championships in Abu Dhabi. He is bilingual in English and German, holds a Master’s degree in contemporary history, law, and political sciences from Ruhr University Bochum, and studied in Tours, France, on a European Union scholarship.

The short version: marketing that creates business outcomes, not just activity.

His articles focus on SEO, paid advertising, social media strategy, lead generation, content marketing, AI search visibility, and how businesses can connect what they spend on marketing to what actually shows up in revenue and pipeline. The audience is typically founders, marketing managers, and professional services leaders who want practical guidance – not trend pieces or inflated claims.

He writes the same way he advises clients: direct, specific, and focused on what moves the needle.
