Serious growth NOW depends on how buying decisions are led.

Professional services growth has quietly changed..

Serious growth does not come from doing more.
It comes from understanding people.

Professional services leaders arrive here because their expertise, reputation, and relationships have taken them as far as they can.

The next stage of growth requires something different.

Not more effort.
Not more activity.
But deliberate leadership of the relationship and buyer intelligence.

Buyology is a diagnostic and activation framework that decodes your firm’s unique behavioural DNA and aligns it with the psychology of your buyers.

The Conditions for Growth Have Shifted.

  • Over 70 percent of professional services buyers say trust in judgment matters more than technical capability

  • Referrals and existing relationships still generate the majority of new work, yet few firms actively lead them

  • Decision cycles are lengthening, not shortening, even when interest is high

  • Leaders report being busy, while confidence in future revenue feels increasingly fragile

In most small to mid-sized professional services businesses, there is no dedicated business development function.

Growth is carried by:

  • partners and directors

  • senior professionals

  • conscientious people who care deeply about standards, clients, and outcomes

Business development happens:

  • between meetings

  • after hours

  • during lunchtime networking

• through goodwill and personal effort

That approach works until growth becomes harder to sustain.

What leaders begin to notice is not failure, but friction:

  • some relationships convert easily, others drain energy

  • decisions slow without anyone explicitly saying no

  • follow-up increases, confidence does not

  • revenue looks healthy, but feels less predictable

This is not a motivation issue.
And it is not a capability issue.

It is a lack of deliberate leadership over how relationships and buying decisions are handled.

What Actually Determines Growth.

After more than 35 years inside professional services, including senior roles at EY and Eversheds Sutherland, one pattern has remained constant:

Clients do not decide based on competence alone.

They decide based on:

  • how trust is built

  • how risk is handled

  • how judgement shows up under uncertainty

  • how steady the relationship feels when things get complex

Most firms sell in broadly similar ways.

But clients do not decide in the same way.

Over decades of commercial work, four distinct buyer decision patterns consistently appear in professional services.

These are not personality labels.
They are decision behaviours.

The Four Buyology™ Buyer Decision Profiles.

When firms default to one style of selling, they unintentionally increase perceived risk for other buyer types.

Buyology™ identifies four primary ways clients:

  • build confidence

  • buyild trust

  • assess risk

  • and move from interest to commitment

1. Stability-Led Buyers

They decide when they feel safe.
They value predictability, continuity, and low disruption.
They withdraw when pace feels rushed or change feels unnecessary.

2. Clarity-Led Buyers

They decide when logic and structure align.
They value precision, coherence, and well-reasoned judgement.
They disengage when information feels vague or inflated.

3. Momentum-Led Buyers

They decide when movement feels purposeful.
They value direction, progress, and leadership energy.
They stall when momentum drops or decisions drift.

4. Relationship-Led Buyers

They decide when trust is deeply established.
They value care, consistency, and being understood.
They hesitate when interactions feel transactional or pressured.

Every professional services business engages with all four types.

But most businesses:

  • default to one selling style

  • and unknowingly misalign with how different clients decide

When decision behaviour is misunderstood, effort increases and momentum fades.

When it is understood and led deliberately, growth becomes calmer, clearer, and far more predictable.

That is the foundation of Buyology™.

What is Buyology™ ?

Buyology is a behavioural intelligence framework built from real commercial environments.

It is:

  • not a personality test

  • not theory

  • not generic “buyer insight”

It IS a disciplined way of understanding:

  • how your business grows through relationships

  • how buying decisions are actually being made

  • how your people behave commercially

  • and where momentum is created or quietly lost

It gives leaders a behavioural map of their business, so growth is no longer carried informally.

The BuyologyProcess.

Buyology gives leaders a behavioural map of their entire organisation transforming business development from a process into a psychology.

Buyology™ is applied through a clear, structured process:

Diagnose

We identify how growth is currently happening through relationships, conversations, and decision behaviour.

Decode

We understand how your people behave commercially and how your clients decide, revealing alignment and friction.

Align

We bring leadership behaviour, communication, and direction into coherence.

Activate

We apply this intelligence deliberately to key client relationships, business development activity, and growth decisions, so growth stops being carried out informally and starts being led.

This process is shown in the Buyology Corporate diagram below.
The spine of the work.

The Measurable Difference.

After implementing Buyology™ :

  • Sales performance becomes predictable: because your teams sell the way your buyers buy.

  • Client retention rises: because your delivery style mirrors your client’s expectations.

  • Cross-department friction fades: because everyone understands how they think and work best together.

  • Leadership becomes lighter: because communication, performance, and culture finally pull in one direction.

This isn’t soft psychology.


It’s behavioural intelligence engineered for billion-pound businesses.

Traditional growth models that focus on systems, skills, or sales scripts, Buyology focuses on human architecture.

What Changes When Buyer Behaviour Aligns.

In professional services firms I’ve worked with, several clients have seen key account retention improve by 30 percent within a year.

When buyer behaviour aligns:

  • key client revenue stabilises

  • retention improves

  • decisions move forward with less effort

  • leadership time is used more effectively

  • pressure across teams reduces

This is not soft psychology.
It is commercial clarity.

Where Leaders Should Start.

Leaders do not need to overhaul their business.

The most effective starting point is a Relationship-Led Review of How Your Business Grows.

This is a senior-level conversation where I assess, using the Buyology™ process:

  • how your business wins work

  • how key relationships are being led

  • how buying decisions gain or lose confidence

  • where a small shift would create disproportionate impact

This is not an audit.
It is not a generic report.

It is judgment, perspective, and direction — applied where it matters most.

Why Leaders Work With Me.

My expertise was built in boardrooms across Europe.
It was refined through lived experience that taught me exactly what pressure does to people.

I understand:

  • how businesses grow under responsibility

  • how trust is earned, not forced

  • how decisions are made when the stakes are real

That perspective sits at the heart of Buyology™.

The Reality of Business Development Today.


Growth models are changing.

Noise is losing effectiveness.
Pressure creates resistance.

Buyers are drawn to businesses that feel:

  • credible

  • human

  • connected

  • and transparent

The future of business development is relational.
It requires judgment, clarity, and deliberate leadership.

That is the work I do.

If you want growth that feels considered rather than exhausting, we should talk.
