About PowerVox
We built PowerVox because we kept seeing the same thing.
Brilliant leaders ‐ sharp, strategic, deeply capable ‐ walking out of rooms where they hadn't said the thing that needed to be said. Not because they didn't know. Because they'd learned, through experience, that speaking up carries a cost.
The Problem We Solve
The system rewards performance. Not insight.
Our team has spent decades in those rooms. As commercial lawyers, barristers, mediators, governance experts, C-suite advisors, and negotiators. Courtrooms, boardrooms, mediation tables ‐ environments where what you say, and how you say it, changes the outcome.
And the pattern was always the same: the people with the clearest thinking were rarely the loudest voices. The system wasn't rewarding insight. It was rewarding performance.
That's the problem PowerVox exists to solve.
Our Team
Most leadership consultancies come from a coaching or HR background. We don't.
Our core team of ten consultants ‐ supported by a wider associate network of around a hundred specialists ‐ bring backgrounds as lawyers, barristers, accountants, governance specialists, negotiators, mediators, and C-suite advisors. Between us, we've negotiated contracts, challenged executives, chaired boardroom meetings, mediated disputes, argued difficult cases, and managed sensitive ethical and regulatory cases. Our PowerVox brand evolved from our history as a niche commercial and legal consultancy - since 2009 we've worked with hundreds of clients on complex deals, change programmes and transformation projects.
We don't teach leadership from theory. We teach the courage to speak truth in powerful rooms ‐ because we've had to do it ourselves.
We work across private and public sector, with SMEs and large corporates. We've worked across many sectors including health, defence, retail, finance, education, maritime, with a particular bias towards technology transformation. Every programme is bespoke, tailored to your strategic goals, because we know that no two leadership teams face the same dynamics.
Founder
Rachel Flower
Founder & Director
I'm a commercial lawyer by training, with decades of experience in negotiation, advocacy, deal-shaping, and mediation. Throughout that time, I honed the ability to craft and communicate powerful arguments, mediate complex disputes, present persuasive business cases, and lead with influence.
But I didn't come to this work through leadership theory alone. I came to it through practice ‐ and through life.
When my daughter was diagnosed with childhood leukaemia, I learned what it means to find your voice when everything is at stake ‐ not in a boardroom, but in a hospital room. To advocate clearly when the noise is overwhelming and the consequences are real. That experience sharpened everything I believe about what voice actually is: not confidence, not performance, but the ability to speak with truth, clarity and conviction when it matters most.
Not theory. Pattern recognition built over decades, tested by life.
I've always been fascinated by the power of the human voice, and I'm passionate about theatre, music, comedy, and connecting people through shared experiences. At PowerVox, I get to combine legal expertise with artistic intuition to help leaders communicate with authority, impact, and heart.
The Insight
There's a third dimension that most leadership development ignores entirely.
We've spent years developing IQ ‐ the intellectual horsepower to analyse, strategise, and decide. We've invested in EQ ‐ the emotional intelligence to read rooms, build relationships, and navigate complexity. But there's a missing piece, and we are now developing it as a proprietary framework and measurement tool. Voice Quotient (VQ).
Intelligence Quotient
Gets you in the room. The analytical power to strategise, decide, and lead.
Emotional Quotient
Helps you read the room. The empathy to build trust, navigate complexity, and connect.
Voice Quotient
Makes people listen. The ability to translate your thinking into influence ‐ to speak in a way that moves decisions, shifts dynamics, and creates alignment.
How We Work
The Voice Ladder™
We don't coach from the sidelines. We work inside the complexity alongside you. Our Voice Ladder framework provides a three-stage approach that meets you wherever you are.
Control
Mastering the mechanics of voice, presence, and delivery. Building the physical and psychological foundation that everything else rests on.
Clarity
Sharpening what you say and why. Structuring complex ideas so they land with precision, every time, in every room.
Influence
Turning voice into strategic impact. Moving decisions, shifting dynamics, and creating the alignment that changes outcomes.
VQ Programme (and Diagnostic)
Our proprietary VQ (Voice Quotient) diagnostic assessment measures and tracks your strategic voice development over time. Our VQ Programme is the foundational six-week cohort-based learning teaching the practical principles for improving VQ over time.
Power Rooms
High-pressure simulated environments led by professional actors, where leaders practise high-stakes conversations in safety.
The Greenhouse
Our private membership communities where leaders continue to grow, challenge themselves, and sharpen their voice beyond the foundational programmes.
What We Believe
Leadership needs to become more human, not less.
As AI gives everyone access to the same knowledge, the leaders who stand apart will be those who can hold complexity, act with conscience, and speak with clarity under pressure.
We all now have an abundance of information. Strong leaders have the IQ to access that information, the EQ to consider how to use it. What's still missing is the clarity of voice to use it well ‐ at the right moment, in the right room, with the right intent.
That's the work. And it's never been more urgent.
What Leaders Say
Words from the room.
The work that PowerVox does is incredibly valuable at this time. It's transformed the way I show up to work, and given me confidence in my own decisions.
I class myself as a confident capable communicator, but what I've learnt through this programme has made me twice as productive and made me a better manager.
We commissioned PowerVox to carry out an audit of a project leadership team and the results were valuable beyond our expectations.
