The Unofficial Co-Founder

A better business. Less weight on you.

An experienced second brain in your business, without hiring a full-time second-in-command.

Most founders don't need another agency, tool or tactic. They need someone who can spot what they're too close to see, challenge their thinking and help them decide what actually matters now.

Growth that gives you more control.

The goal isn't simply a bigger business. It's a commercially stronger one that makes better decisions, creates more value and depends less heavily on you.

+ Better decisions

An experienced second opinion on the decisions you're currently carrying alone.

+ More commercial leverage

Sharper offers, pricing, acquisition, retention and customer value.

+ Less founder dependency

Clearer ownership, fewer distractions and more control over your time.

You have a real business. But too much of it still rests on you.

You don't need someone to tell you to work harder. You need someone to help you decide where your effort will make the biggest difference.

  • Too many decisions still land with you.
  • You're busy, but unsure you're focused on the highest-value work.
  • Growth has slowed and you're not sure what to push next.
  • You're questioning pricing, marketing, offers, people or investment.
  • You want growth without your workload growing at the same rate.
  • You need a strategic partner, not another agency or tool.

Find where the leverage sits.

We assess the business through four commercial lenses, then focus on the small number of changes most likely to improve revenue, margin or your workload.

B

Belief

Why should someone choose you? Positioning, trust, authority and differentiation.

B

Buyer

Do we understand why people buy? Customer insight, messaging and acquisition.

B

Basket

Are you making enough from each customer? Pricing, margin, AOV and lifetime value.

B

Bond

Does growth compound? Retention, referrals, repeat purchase and systems.

And then there's you.

“The goal isn't to remove you from the business. It's to help you spend more time where you can have the biggest impact.”

A visible journey, not a series of loose conversations.

We work in a simple cycle: diagnose what's really holding the business back, choose the few priorities that matter, then act and learn.

Diagnose

We look at the 4Bs alongside your numbers, team, workload and current priorities.

Prioritise

We identify one to three moves most likely to improve revenue, margin or founder load.

Act & reassess

You and your team execute. I challenge, review, troubleshoot and help us choose what comes next. When extra support is needed, I can recommend the right specialist or help you hire.

The answer isn't always more.

Sometimes the biggest opportunity isn't more customers, products, people or tools. It's making what you already have work better.

A stronger business that depends less heavily on you.

You should have clearer priorities, stronger commercial performance, greater ownership across the team and fewer decisions unnecessarily landing on you.

Depending on where the leverage sits, we may work on your offer, pricing, customer journey, retention, team ownership, systems or financial visibility.

A second brain when you need one. 🧠

Monthly strategy session

One focused 60-minute session to review progress, find the biggest opportunity and agree the next priorities.

Ongoing access

Questions and decisions rarely wait for a scheduled call. Run them past me as they arise.

Clear ownership

We decide what matters and why. You and your team own execution; I help keep it focused and moving.

I've sat on your side of the table.

I spent almost a decade building a restaurant chain, taking it from a small Shoreditch food stall to a multi-location, multi-million-pound brand.

I've dealt with the parts of entrepreneurship people don't tend to put on LinkedIn: growth, staff, agencies, suppliers, cash flow, expansion, difficult decisions and what happens when things don't go to plan.

I now bring those scars and lessons into founder-led businesses — without you giving away equity or hiring me full-time.

+ Greater clarity+ Better decisions+ Stronger performance+ More control

You don't have to take my word for it.

Six months to make the business meaningfully better.

£1,000/month

Paid monthly · 6-month commitment

£6,000 total

Why six months? Meaningful improvements rarely come from one clever conversation. We need enough time to understand the business, make changes, see what happens and adjust.

The right fit sees this as an investment in better decisions — not another business expense.

  • ×You're pre-revenue or still finding the basic model.
  • ×You're looking for someone to execute everything.
  • ×You want a quick hack rather than meaningful change.
  • ×You don't want your thinking challenged.

What happens if nothing changes?

If you continue running the business exactly as you are today, will your life and your business look meaningfully better 12 months from now?
