About Gavin Erasmus.

I run a one-architect advisory that builds the operating system a business runs on, and then runs it. The firm exists because the shape of professional services is changing faster than most consultancies are willing to admit, and because the buyers I care most about are tired of paying for slide decks.

I have worked in advisory since 2008, when I left Accenture to start my own consultancy in London. For the better part of a decade it delivered multi-million-pound strategy and change programmes for FTSE100 clients in regulated financial services and energy, including a £60bn loan book migration, a whole-of-bank lending strategy, a global fuels supply-chain integration, global IT reorganisations, and regulatory delivery under real scrutiny. The five years before that were spent at Accenture in energy and supply chain, across the UK, South Africa, and Mauritius.

Since then the work has moved between sectors and geographies. I served as Technology & Innovation Lead for UNDP in Saudi Arabia, based in Riyadh, leading the digital innovation programme for a national environmental agency. I advised the Green Digital Finance Alliance, a UN Environment Programme partnership, across Africa, and co-authored published work on fintech for biodiversity. I have also built ventures of my own: a carbon-negative fashion brand in London, a renewable energy certificate business, and a biodiversity-credit platform.

I led digital transformation in education across that same period. Across all of it, the pattern was the same: the wins came from architectural choices made early and held to under pressure.

I am also Head of Digital Strategy and AI at Michaelhouse, the 130-year-old South African school I matriculated from. That is an operating role rather than an advisory client, and it keeps me close to the work. The patterns I bring to client engagements are ones I run day to day myself, under real budgets and real scrutiny.

What changed in 2024–25 was not the method but the leverage: systems which carry the operational load make the senior practitioner more leveraged, not less. Work that would once have needed a team can now be carried by one architect, without diluting it. That is the thesis behind the firm in its present form.

I work with CFOs, CEOs, COOs, and Programme Directors at organisations that take governance seriously. I publish the method, not the engagement detail. References available on request to qualified prospects.
