Hi, I’m Marianne Lehnis.

I'm a Freelance Content Marketing Writer

and 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 marketing writer. 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 marketing writer, I help companies do the same: find the right ideas to create inspiring content that engages and informs their target audience.

My journalistic work has appeared in titles including BBC Technology of Business, Forbes, Startup Magazine, Medium, Engadget and the Powerlist magazine. Exploring innovation-driven change to propel a green economy is central to my work; I thrive on turning the abstract into interesting, upbeat, and where appropriate, humorous stories.

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.

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.
