explain: How a PowerPoint Agency Became the Go-To Partner for Germany’s Top Corporations
)
Interview with explain CEO Jonas Keller
explain is a German agency that has mastered a very specific craft: designing and refining PowerPoint presentations. What started as a niche idea has grown into a powerhouse trusted by some of Germany’s biggest brands including companies listed on the DAX, the country’s premier stock index.
It all began in 2004, when founder Sven Hager recognized the untapped potential of professionally designed presentations after working on a project for energy giant EnBW. The first office? His mother’s ironing room.
Two years later, Jonas Keller joined without a college degree, but with a bold spirit. Together, they transformed explain from a one-man venture into one of Germany’s leading presentation agencies. Their mission has remained clear:
Make complex ideas easy to understand, visually engaging, and emotionally impactful.
"World-class explanations - that’s what explain has delivered for years.“
From Niche Player to Market Leader
What sets explain apart is its laser focus on what many overlook: PowerPoint. While other agencies chase trends in branding or social media, explain specializes in what businesses need every single day presentations that truly persuade.
With a team of designers, coaches, and storytelling experts, explain empowers executives, leadership teams, and entire organizations to communicate clearly and confidently.
Culture Over Commerce
At one point, the company planned a big move to Baden-Baden to accommodate its growing team and clientele. But despite CEO Keller’s enthusiasm, the project was unexpectedly canceled for a very deliberate reason: to protect the company culture.
At explain, people come first. Growth is never pursued at the cost of well-being. The decision reflects a deeper belief: real professionalism isn’t just client-facing it’s lived every day within the team.
