Hi, I'm Stefan Kollenberg.
I’m a content marketer.


I’m here to create content that will add value to your audience.


  • “Working with Stefan has been a delight. He's extremely thoughtful and has this great balance about him - first he sits back and listens to understand your business, target market, your goals and philosophies and then he collaborates and brainstorms with you like he's part of the team. You quickly feel like you've know Stefan for a long time and his passion for good content is contagious. His expertise across various formats - twitter, Instagram, Facebook, LinkedIn, and blogging - goes a long way in terms of engaging your target audience.”

  • “The articles Stefan wrote were superb and we were impressed with his full-service approach: conducting background research, interviewing students, designing accompanying web ads and handling all social media distribution (HigherEdPoints and external). We'd highly recommend Stefan for any content marketing projects.”
    Suzanne Tyson
    Founder, HigherEdPoints Inc.
  • “You don't generally associate the word "perseverance" with most marketers, but it's one of Stefan's defining qualities. While continuously working with Neutun, Stefan brings high quality content focused on users with an efficiency you don't generally see with writers. I would recommend Stefan to any startup looking for fast growth, and effective content marketing.”

  • Stefan provided high quality, affordable ghostwriting services with timely work completion. He was quick to adapt and learn in a fast-paced project. Stefan is an effective B2B writer and I highly recommend his services.
