Sebastian Fieber is the founder of DEFCOM ONE – Europe’s first dedicated Defence Communications Agency. He blends creative precision with operational thinking, shaped by years of experience in the intersection of strategy, storytelling, and impact.

As a photographer, filmmaker, and digital strategist, Sebastian has delivered content for global brands like Samsung, The North Face, HP, and Adobe. He built an Instagram account from scratch to over 100,000 followers, led cross-platform campaigns, and turned content into consistent, measurable reach. He doesn’t just create – he scales.

Most notably, he served as Head of Content for the Invictus Games Düsseldorf 2023 – one of the most high-profile international sporting events of the year. In this role, he was responsible for the overarching media concept, global social media presence, and a team producing everything from campaign trailers to daily content. The result: millions of views, international press coverage, and a digital presence that moved people and policy.

Now, with DEFCOM ONE, Sebastian is building what Europe has long lacked – a communications agency that understands the unique needs of the defense and tech sector. No fluff, no filler – just smart, fast, effective comms that cut through.
