I work with founders, executives, and senior leaders who sense that something important is shifting in their organization, their leadership, or how decisions are being made, and want to respond intentionally rather than reactively.
I live by a simple principle: plant seeds that will grow trees I will never sit under.
After nearly a decade deeply invested in a single organization, I reached an inflection point in 2024. Instead of rushing into the next role, I slowed down just enough to think clearly, then returned to the work I’ve always done best: helping leaders see themselves and their organizations more truthfully.
I’m known as The Business Polygraph because I have an uncommon ability to surface what is real, quickly, calmly, and without agenda. I help leaders hear what their teams, systems, and results are already telling them, but haven’t yet had the space or language to confront.
My background spans operations, product, sales, investor relations, people leadership, and AI across industries including technology, finance, manufacturing, education, and energy. I’ve worked across Africa, Europe, the UK, and North America, in both growth and contraction, with organizations large and small.
I’m the author of You Decide and Leading Magnanimously. My work focuses on leadership, decision-making, culture, and the human implications of AI, not as tools, but as forces that reshape authority, accountability, and trust.
I’m a strong fit if you are:
- A founder or executive who feels like too much depends on you
- A leader navigating growth, transition, or complexity
- Someone adopting AI but unsure how it’s changing decision-making and leadership
- A senior professional preparing for bigger scope or board-level responsibility
- A thoughtful leader who wants clarity, not hype or tactics
I’m less helpful if you’re looking for:
- Step-by-step playbooks
- Startup “growth hacks”
- Tool tutorials or certifications
How I Work With Mentees
My style is calm, direct, and grounded in real experience.
I use conversation (often Socratic) to help you:
- See blind spots and patterns you’re too close to notice
- Separate signal from noise
- Clarify what only you should own and what you must let go of
- Design leadership and decision systems that scale
- Use AI intentionally without surrendering judgment or accountability
I don’t tell you who to be.
I help you become more of who you already are, with less friction and more leverage.
From our work together, mentees typically gain:
- Sharper judgment and decision confidence
- Relief from constant escalation and over-involvement
- Clearer leadership boundaries
- Better conversations with teams, boards, and investors
- A sense that they’re no longer carrying everything alone
If you’re carrying hard truths — or softer realities — and want a place to think clearly without performance or posturing, I create that space.

Andrew’s a great mentor. He really helped me see the bigger picture and dig into what was actually going on. What stood out is how well he listens sometimes it felt like he got what I was trying to say even before I found the words. His style was honestly a breath of fresh air for me. Our conversations always went deep and felt super focused, mostly because of his energy and attention. Before working with him, I was pretty anxious and didn’t know where to channel all my energy. Now I feel a lot more clear and grounded, and I’ve found a good outlet for that energy, thanks to him.
