Guardian Media Group has promoted Mylene Sylvestre to the title of managing director of publishing and e-commerce.

Sylvestre will assume commercial responsibility for the Filter, an independent product reviews guide. She also will continue to lead on print publishing and the development of new digital formats.

This hire is part of the Guardian’s strategy of innovating and diversifying its product portfolio. The brand is tapping into both its print and digital products. 

During almost three decades at The Guardian, Sylvestre has driven many print and publishing achievements: from the moving to the tabloid format, transforming Guardian Weekly into an award-winning magazine, and relaunching of the Guardian’s Saturday print package. In her most recent role, she was director of publishing, rebuilding the long-term commercial sustainability of the Guardian’s print products, the company says.  

“As our audience needs continue to evolve, we see increasing opportunities for the Guardian’s print and digital products to mutually reinforce each other,” says Liz Wynn, chief supporter officer of Guardian Media Group, to whom Sylvestre will report. “Mylene has been instrumental in shaping the Guardian’s publishing success over many years and this new role is a natural next step. Her experience, creativity and commitment to innovation will be invaluable as we continue to diversify our product portfolio and grow new areas of the business.”
