Strategic Support for Your Portfolio Companies

High-touch mentoring and strategic advisory for the founders you’ve invested in.

Capital opens the door. Strategic clarity moves the business forward.

I partner with venture funds, accelerators, and founder-led syndicates that want to offer more than capital. The Portfolio Growth Partnership is a way to support your most promising companies with tailored, high-level mentoring, so they’re not just growing, they’re growing well.

This is strategic, implementation-focused partnership designed to increase founder resilience, execution clarity, and long-term traction.

Why This Matters Now

Today’s portfolio founders are facing:

  • Intense pressure to hit milestones fast

  • Decision fatigue in uncertain markets

  • Growing teams, unclear roles, and leadership strain

  • Operational bottlenecks that slow execution

  • Burnout risks, even when revenue is growing

Even high-potential investments can stall, not because the idea is wrong, but because the founder is stretched too thin.

The solution?
Founder-level strategic support: clear, grounded, and built to evolve with them.

Why Portfolio Mentoring Creates Real Value

Smart investors know the real multiplier isn’t just capital. It’s founder performance over time.

The Portfolio Growth Partnership helps your founders:

  • Lead with confidence through complexity

  • Build scalable systems without spinning out

  • Gain strategic space to think, plan, and act

  • Develop sustainably as leaders, not just operators

For the fund, this means:

  • Stronger founder retention

  • Smarter execution

  • Better board conversations

  • A clear signal to LPs that you back your founders all the way

Value Beyond Capital Is No Longer Optional

A Harvard Business School study reports that three out of four venture-backed startups never return investor capital, and up to 40% end in total loss.

This isn’t about funding gaps; it’s about support gaps.

Your founders are under immense pressure to deliver growth, clarity, and performance at speed. Yet too often, they’re navigating it all without a strategic partner who’s walked the road before them.

The difference between a struggling founder and a scaling one? Often, it’s not their product. It’s the level of support they receive.

With the Portfolio Growth Partnership, you elevate your value as an investor, not by doing more, but by enabling more.

Flexible Partnership Models That Work With Your Fund

This is a flexible, founder-first deployment of my Growth Partnership model, tailored for selected companies in your portfolio.

Supporting founders at scale isn’t easy.

As a fund, you’re juggling:

  • Multiple founder personalities, needs, and maturity levels

  • A demand for high-touch support, with limited internal capacity

  • The pressure to show LPs that you offer more than just capital

  • The risk of founders spiralling or stagnating between check-ins

  • Inconsistent impact from generalised coaching or reactive interventions

You want to be a strategic, founder-centric partner, but without adding another layer of complexity to your team.

That’s exactly why this model is flexible.

➤ You decide:

  • Which founders are enrolled, and when

  • Whether support is fully funded, subsidised, or opt-in

  • Whether to combine 1:1 mentoring with cohort-based workshops

  • Whether you want light-touch insight reports across engagements

This structure flexes to fit your investment thesis, your internal bandwidth, and the realities of your portfolio stage mix.

Strategic Partnership, Founder by Founder.

Your founders don’t need more “motivational” group calls.
They don’t need frameworks that weren’t built with their growth stage in mind.
And they certainly don’t need another external consultant who talks in circles but never gets their hands dirty.

What they need is sharp, grounded support.
The kind that unlocks strategic clarity, execution momentum, and sustained growth.

It’s a bespoke strategic partnership grounded in lived experience, real business results, and tailored implementation.

I bring decades of experience advising global brands, scaling startups, and mentoring visionary founders.
But more than that, I bring the tools and thinking needed to sustain performance under pressure.            At the heart of our work is The P.A.C.I.N.G. Principle™ my proprietary framework for mastering  the pace of growth, decision-making, and leadership timing, so founders and their teams move forward without burning out or stalling.
And infused throughout is The Quiet Edge™ my philosophy that equips founders to lead from clarity, not chaos, especially as complexity increases.

Your founders don’t need more noise.
They need structured, personalised guidance from someone who sees what others miss.
And helps them move with more precision, confidence, and staying power.

What Your Founders Get Tailored to Their Growth Stage with depth and structure

Each selected founder receives a private Growth Partnership experience, tailored to their stage, goals, and business complexity. This includes:

  • 4 x 90-minute 1:1 mentoring sessions per month

  • Unlimited support via WhatsApp and email in between sessions

  • Tailored resources, templates, and strategic workbooks based on their stage

  • Live strategy design and implementation support, not just planning, but doing

  • Optional sessions involving co-founders or senior team

  • Progress summaries (if desired) to keep you in the loop

Why Work With Me

When you bring me in to support your portfolio, you’re not outsourcing vague “coaching”
You’re securing an experienced strategic partner with a boardroom-to-startup track record.

I bring over 20 years of leadership experience across corporate giants, high-growth startups, and founder-led businesses. Not just as an advisor, but as a C-level leader, board member, and hands-on growth partner.

I’ve sat in the rooms where high-stakes decisions are made.
I’ve helped build brands from scratch, scaled businesses across global markets, and led teams through complexity, ambiguity, and transformation.

More recently, I’ve mentored founders backed by respected institutions like LSE Generate, Enterprise Nation, and industry-leading investors. My work has been featured in The Times, and recognised with a national award for outstanding contribution to business mentoring.

What sets me apart is the combination of strategic clarity, operational precision, and deep emotional intelligence that founders often lack in external support. I know how to speak both languages: the founder’s world and the investor’s agenda.

If you want someone who will:

  • Cut through the noise and get to the heart of what’s blocking progress,

  • Elevate your founders’ leadership and decision-making capacity, and

  • Protect the long-term value of your investment by embedding real strategic thinking

That’s where I come in.
