Hey there, I'm Jennifer Kumer

Your Creative Sidekick & Game Designer Extraordinaire

I’m on a mission to partner with people changing the world to develop and launch their own play-based tools that bring important ideas to life.

I’ve been designing games my whole life, starting with a companion game for my mom’s first book. I saw how this game allowed people to immerse themselves in her message and come away transformed.

Now, I combine my expert knowledge of game mechanics, design thinking, and strategic consulting to co-create play-based tools with my clients. Together, we’ll embark on a creative journey to connect with your audience through the power of play and bring your thought-leadership to the world in a fresh, new way.

I’m an award-winning designer with a passion for games that make the world a better place.

What my clients say:

"I'm deeply grateful to Jennifer for her beyond amazing abilities to turn content into interactive gameplay. She revolutionised my thinking around content delivery and supported me the entire way through the process. In the end we turned a book into an interactive tool which captivated my audience and brought the concepts to life. Her creative approach and seamless collaboration made the process a breeze. I highly recommend Jennifer and her play-based tools to fellow authors and consultants who want to make a lasting impact!"

- Andy Chaleff, Author & Consultant

"Jennifer is a game-changing force in the world of game design and product development. Her expertise and guidance took my prototype, 'The Motivation Kit,' from an idea to a successful product and launched it in my webshop. With her help, I not only sell the kit but also conduct workshops and training sessions. Jennifer's strategic insights and collaboration have elevated my business to new heights. If you're looking to transform your game or toolkit into a market-ready success, Jennifer is the ultimate partner you need by your side!"
