  • — Caroline Wren, CEO, MTM

    "She... took us from DIY founder-led marketing into a much more professional outfit...

    It's likely that Di's professionalising of MTM's marketing function may have had a bearing on us attracting the attention of various potential investors including our actual buyers..."

  • — Daniel Pitchford, CEO, Collingwood

    “Diane joined Collingwood as our fractional CMO and immediately hit the ground running. She was instrumental in sharpening our brand thinking and moved the needle on several key GTM initiatives with impressive speed.

    She is a high-impact leader who navigates complex stakeholder environments with ease."

  • — Michal Cohen-Sagi, CEO, Vidavii

    “Diane puts her full self in it. [She has] a very professional way of thinking, understanding and thorough leadership. She uses that quiet, powerful leadership in a very gentle way… And that's a very, very powerful thing."

  • — Caroline Wren, CEO, MTM

    "If you're thinking of engaging Di's services - go for it!"

  •  — Eloïse Ghertman, CEO, Aimigo

    “Diane enabled us to make a crucial and beneficial turn in the positioning and strategy of our brand.

    The support was perfect and even exceeded our expectations, both in terms of availability, responsiveness, and effectiveness, as well as on the quality of the deliverables and the human aspect of the relationship. We will definitely reach out to her again without hesitation."

  • — Laura Curtis, Marketing Communications Lead, EIT Food

    "Diane has a remarkable ability to create an environment where people feel comfortable contributing, sharing challenges, and exploring new ideas...

    Beyond her skills as a facilitator, and of course her exceptional knowledge as a CMO, Diane is a fantastic colleague to work with. She is collaborative, thoughtful, professional, and genuinely invested in the success of the people she supports."

  • — Seb Juviler, Founder & Co-CEO, Forever Audio

    “Diane joined Forever Audio back in 2025 as a fractional CMO and quickly familiarised herself with what is a complicated technical business with multiple revenue streams. She is a fountain of knowledge and mentored our marketing manager brilliantly. They pulled together an ambitious, well rounded plan in short order and she was always sales focused.

    Diane brings energy and drive to every meeting, whilst always bringing the team along with her… she’s a joy to work with! I couldn’t recommend Diane enough to anyone looking for an experienced, fractional marketing leader.“
