Who We Are

MIX Diversity Developers - Debra Searle MVO MBE
Debra Searle MVO MBE


Debra founded MIX and is our Head of Consulting. She has always been a successful woman in a man’s world having taken on some of the toughest conditions and events on the planet, including rowing across the Atlantic solo and sailing around Antarctica.

She was also the youngest and only woman at the time to be appointed to the Board of Trustees for The Duke of Edinburgh’s Award, one of the UK’s biggest youth charities, working alongside HRH Prince Philip and HRH Prince Edward. This gave her ten invaluable years of experience of being the only woman at the boardroom table.

Debra was heavily involved in the formation of the Women’s Business Network Forum based out of Buckingham Palace and chaired by HRH The Countess of Wessex. The Forum brings together leaders of some of the biggest women’s networks in the UK including BP, Ernst & Young, Merrill Lynch, HSBC and Google to share best practice and to provide a platform for innovative debate.

Debra has also worked with companies such as Tesco, HSBC and eBay on developing female talent and seeking to stem the leaky pipeline of women to senior posts. She is proud to be a member of the 30% Club.

David Scott


In his executive career David was HR Director at United Utilities plc, BT Group headquarters and was Director of Personnel for HM Prison Service of England and Wales.

Recent interim experience involved being Chief Executive of the Duke of Edinburgh’s Award, and HR Director in the Strategic Rail Authority, the NHS and First Group plc.

David’s expertise is in managing structural and culture change in large and complex public and private sector organisations. He is an accredited practitioner for a number of psychometric assessment tools.

Deb Gale is MIX’s resident Ageing aficionado. Her expertise in Gerontology (‘Ageing’ to laymen) has led her to become a regular contributor to The Huffington Post. She addresses the issues surrounding an ageing population and how that interacts with and affects the business world in an engaging and practical way.

Deb is a research fellow at the BioCentre on Ethics, an affiliate director for and senior storyteller for AONR - Age of No Retirement. She has had work published in The New Bioethics: A Multidisciplinary Journal of Biotechnology and the Body, Journal of Intergenerational Relationships and The New Bioethics: A Multidisciplinary Journal of Biotechnology and the Body.

Deb is an Apple Computer veteran, serial ex-pat and mother to five daughters, so she also knows a thing or two about women in tech and cross-culturalism.

Matt’s one of those brain boxes that regularly floors us with his brilliance! He has an MA from Oxford and an MBA with Distinction from Cass Business School (thankfully, he’s also very modest!).

Matt has significant experience in the culture piece around national differences and how to work effectively with people from a range of cultures.

He is also passionate about mental health and the workplace and is a compelling speaker on this subject.

Our Founding Principles

All of our work is built upon two main principles:

MIX Diversity Developers - Research
We are research-driven

The D&I space is at a very fluid stage.

There is a huge amount of research underway and being released almost daily.

One of our founding principles is to ensure we’re able to distill and communicate the best research to meet the needs of our clients.

MIX Diversity Developers - Storytelling
We use storytelling to change hearts and minds

This may seem at odds with much of the statutory / policy-driven Diversity & Inclusion agenda but storytelling is part of our DNA at MIX.

We believe that stories matter. People can relate to and identify with stories better than any other medium.
