Hi, I’m Marianne Lehnis.
I’m a Freelance Content Strategist
& Multimedia Journalist
About Me


My love of communicating and curiosity about our incredible world and the forces that shape the change we see led me to a career as a freelance multimedia journalist and content strategist. I’m London based, but have worked with Fortune500 brands and high-growth startups around the world.
I specialize in greentech and entrepreneurship, sourcing interviews and insights for my Forbes Contributor column and my newsletter, The Green Techpreneur.
I’ve used content strategies to grow a targeted list of engaged email subscribers to my newsletter, which is read by hundreds of greentech professionals around the world.
As a freelance content strategist, I help greentech companies do the same: find the right ideas to create inspiring content that engages and informs their target audience.
Exploring innovation-driven change that propels a green economy to is central to my work: I thrive on helping companies turn abstract environment and science-related topics into interesting, upbeat, and where appropriate, humorous stories.
Speaking to outstanding people from all walks of life and sharing their myriad of life experiences is a key perk of the job that I draw a lot of inspiration from. My journalistic work has appeared in titles including BBC Technology of Business, Forbes, Startup Magazine, Medium, Engadget and the Powerlist magazine.
I’m fully committed to using my career to highlight issues that matter and focus attention on the big questions facing our fast-changing, high-tech world.
What Editors Are Saying


Marianne wrote a great piece for this year's Powerlist. She stayed true to the brief and delivered a powerful read. It was a pleasure to commission her and I would certainly recommend her to any editor.
