The Portfolio Growth Partnership


Premium Partnership for Growth-Focused Funds

If you're an investment partner looking to offer more than capital, this is where value is created. The Portfolio Growth Partnership is a bespoke mentoring experience designed to equip your founders with the clarity, structure, and leadership support they need to scale, not just faster, but better.

This is not a group programme. Not surface-level advice. It’s a high-touch, tailored mentoring partnership that unlocks strategic capacity at founder level, turning pressure into performance and ambition into traction.

Let’s turn potential into progress.

Why Portfolio Mentoring Creates Real Value

Behind every great company is a founder making high-stakes decisions daily.

But many of them are doing it alone, without a seasoned partner who can help them think, lead, and grow more strategically.

As a portfolio manager, you want to:

  • Protect your investment by supporting smarter execution.

  • Reduce risk by increasing founder clarity and decision-making.

  • Enhance exit outcomes with stronger business foundations.

  • Add tangible, high-level value that differentiates your fund.

That's what founder-focused mentoring unlocks.

When founders have the right strategic support, they make better decisions, lead more effectively, and build businesses that go the distance.

This Is Not Coaching. It’s Not Therapy. It’s Strategic Partnership.

This isn’t about asking better questions. It’s about helping founders make better moves.

I don’t offer passive support or surface-level conversations. This is high-calibre mentoring that goes deep into:

  • Business model clarity

  • Scalable systems

  • Strategic decision-making

  • Leadership development

With my proprietary P.A.C.I.N.G. Principle™ and The Quiet Edge™ embedded throughout, this is about building businesses that grow smart, without spiralling into chaos.

The Harsh Truth? Capital Isn’t Enough.

A Harvard Business School study found that 75% of venture-backed companies never return cash to investors, and up to 40% result in complete losses.

Why?

Because even with funding, many founders struggle to build the operational clarity, strategic structure, and leadership capacity needed to scale.

They don’t just need money; they need meaningful partnership.

That’s where your fund can create a real edge: by investing not just capital, but strategic capacity. That’s exactly what the Portfolio Growth Partnership delivers

Flexible Partnership Models

You want to support your founders. But not by creating more operational complexity.

This is a white-glove solution that offers hands-on strategic mentoring without draining your team’s time.

Most portfolio partners tell me they:

  • Struggle to offer tailored strategic support across diverse businesses

  • Don’t want to dilute internal resources across mentorship and operations

  • Want to avoid "one-size-fits-all" training programmes that lack depth

You decide how the model fits:

  • One-to-one mentoring for selected founders

  • Fixed-term growth tracks (e.g. 3- or 6-month cycles)

  • Ongoing strategic advisory for key ventures

Let’s shape a partnership model that fits your portfolio’s needs.

WHY WORK WITH ME?

When you choose to work with me, you're not signing up for vague “mentoring” or generalised coaching.

You’re partnering with someone who brings over 20 years of experience across global corporations, high-growth startups, and founder-led ventures, not just as an advisor, but as a C-level executive, board member, and hands-on business builder.

I’ve sat in the rooms where critical decisions are made.
I’ve scaled brands across markets, led through transformation, and built teams from the ground up.

More recently, I’ve mentored founders backed by institutions like LSE Generate, supported scale-ups across industries, from aerospace to wellness, and been featured in The Times for my impact in the field.

I was also recognised with a national award for outstanding contribution to business mentoring.

What sets me apart?
I combine strategic sharpness with operational depth, and I understand the emotional weight of leading through growth.

If you're looking for someone who will:

  • Help you cut through the noise and move decisively

  • Elevate your leadership and business architecture

  • Create calm momentum without compromising ambition

This is where we begin.
