Who We Are

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

debra[at]mixdiversitydevelopers.co.uk

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.

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.
