Buki Mosaku

Born in west London to Nigerian parents, Buki started his corporate career in media and advertising before moving into consultancy in the City of London. He then went on to found RosAcad, an international business and sales training consultancy and latterly DiverseCity Think Tank- Workplace Bias Navigation Experts and D&I consultants. In his work as a communication expert, consultant, and coach to tens of thousands of global clients’ staff over more than two decades, he became acutely aware of the impact of the multidirectional nature of workplace bias in stifling otherwise prosperous careers including his own at times.

Buki also became aware of popular, well-meaning yet unworkable so-called expert and academic theories to combat racial, disability, gender, sexual orientation bias etc, such as IAT- Implicit Association Tests, traditional microaggression training, ‘White Fragility,’ ‘Anti-racist Consulting’ and so on, that actually hinder the people they purport to help as well as reduce group wide productivity.  Buki himself has grappled with unconscious (and indeed conscious) bias with varying degrees of success in his employed career and as a consultant in the city.

Frustrated with his own challenges and the inadequacy of behavioural experts, authors, and consultants’ attempts to address workplace bias, he set out to develop a fair, equitable results-oriented methodology to tackle person(s) to person(s) bias effectively in the workplace. His forthcoming book “I Don’t Understand” –Navigating Unconscious Bias in the Workplace is the culmination of more than two decades of working, observing, and interacting with over 50,000 individuals throughout the world as a consultant, communications expert, trainer, and coach.

With disarming honesty, humour, enthusiasm, and a rare breed of clarity void of guilt or pain, Buki empowers and equips audiences of leaders and staff alike to effortlessly navigate what he describes as “the inevitability of workplace bias”.

Buki has cracked the code for calling out unconscious workplace bias to stop it in its tracks. The basic premise is simple: Traditional corporate training solutions tend to follow the counterproductive model of Guilty Perpetrator v Hapless Victim. Buki will explain why this approach is unproductive and counter intuitive. Even better, he will present a more effective model to navigating ALL workplace bias and show audiences How to Think, What to Say, When to Say it and the Way to Say it, so that you can put career stifling and conflict generating workplace bias behind you, your colleagues and team once and for all. As a leading business consultant Buki has worked with global industry giants including: Shell, BNP Paribas, M&S, Goldman Sachs, American Express, Aon, HSBC and more.

"It's fascinating what you do...I've learnt a bit more... You've done a fine job so I'm grateful"

Nick Ferrari, LBC & Sky Presenter

"It was an incredibly insightful session, which all should take notes from. Discussing sensitive topics that corporate companies usually don’t like to talk about was needed to break the barrier of formality. I would recommend all to join the session."


"Buki is a fantastic speaker, he keeps everyone engaged and delivers with such energy. His passion shines through and I have been able to use what I have learnt on this course with many other topics too."

Aston Lark

"Wow Buki you really do talk so much sense, I could listen to you all day. We need to have a better understanding of reverse bias and work together. You should be a mandatory part of any firm's training program"

Trivium London Consulting

"This was an excellent training session. I feel strongly that it should be rolled out to all Aon colleagues as a compulsory session to help develop an inclusive culture where all colleagues are respected and better understand their interactions. This will also help with working with our clients."


"I have never seen such enthusiasm shown on a webinar before. Buki should be Prime Minister!!"


I have just listened to Buki's summary covering directional bias, reverse bias and defensive fragility and it's powerful stuff. Worth a listen and consideration, as the industry looks to embrace D&I”.

David Sparkes, Head of Compliance & Training at British Insurance Brokers Association

I must say my colleagues are still positively referencing your session Buki…. People on both sides of the Atlantic found it a very invigorating discussion!

Julian Lynne, Chief Commercial Officer-Newton Investment Management

The session was delivered with such energy, respect and pragmatism. We still use quotes in our meetings today. A really clear strategy was laid out as to how to categorise interactions and then options for responses which moved away from victim, blame and reaction to personal choices and liberation from stereotypes. Buki was right in the moment with us, totally engaged and utterly engaging - you couldn't help but be inspired.

Kate Howlett, Executive Coach & Career Transition Consultant LHH

I felt it was well thought through and very, very well delivered. It was engaging, fun, (based on real life, not just theory) and easy to digest and put into practice…Genuinely one of the most thought-provoking and useful sessions I’ve had in my career. Can’t thank you enough
