The eigenvector thesis
From the founder
Twenty-five years ago, I started helping businesses grow through organic search. Back then, it was simple: create something useful, make it findable, watch it compound.
The tools have changed. The algorithms have changed. AI has arrived. But the principle hasn’t.
In linear algebra, an eigenvector is the one direction that holds steady when a transformation is applied. Everything else deflects. The eigenvector scales. That’s what I build for businesses: the fundamental growth direction that compounds through every shift.

Principles
How we work
British directness
Lead with the answer. No hedge words, no consultant waffle.
Conservative projections
We’d rather under-promise and over-deliver. Every number we cite, we can defend.
Operational integration
We embed organic visibility into how the business works, not as a side project.
Honest assessment
If the honest answer is ‘you don’t need us,’ we say it.
