The "Unfair Advantage"

Leigh Stallard is not a "career consultant." He is an operator who spent 10 years in the trenches of accounting firms and 11 years in high-growth FinTech/SaaS (Xero, Soldo, Satago).

The Practitioner Lens

He understands why accountants ignore vendor emails (cognitive load, not ignorance). He speaks the language of "Debits, Credits, and Timesheets."

The SaaS Growth Lens

As an early employee at Xero UK, he understands the pressure of "SaaS Metrics" and how internal vendor politics can destroy customer value.

The Change Management Lens

He applies formal behavioural science frameworks to solve what others mistakenly identify as "product problems."

The Creator Lens

He doesn't just design the strategy; he produces the necessary digital assets to execute it at scale.

25 years of bridging the gap between practice and technology.

"Flow Science" Methodology

We use proven, science-backed models developed by the Behavioural Insights Team and used by the UK Government. These frameworks allow us to reverse engineer our 20 years of experience in accounting and accounting tech, ensuring insights can be effectively applied to close the Activation Gap.

Diagnostic Depth

We diagnose why a partner or staff member is not taking action by analysing the intersection of capability, opportunity, and motivation.

Behavioural Interventions

We design interventions that make the desired behaviour easy, attractive, social, and timely, ensuring frictionless adoption and clear value.
