WHAT I DO
Turn complex Finance and Treasury change into working operating capability. I lead transformation across treasury technology, ERP and finance platforms, processes, controls, data and operating models — from mobilisation and design through implementation, cutover, adoption and stabilisation.

M&A, Carve-Outs &
Integration
Make the operational side of a transaction work. I lead transaction-driven change across Finance, Technology and Operations — defining what must separate, migrate, integrate or stand alone from pre-deal assessment and Day 1 readiness through carve-out, integration and post-deal stabilisation.

Programme Recovery & Operating Models
Move complex programmes from ambiguity into delivery. I step into transformations that need clearer ownership, stronger governance or a practical route from strategy to implementation — mobilising or recovering the programme, shaping the operating model, aligning stakeholders and getting the change through go-live and stabilisation.

Selected Works
Pre-Deal Carve-Out & Separation
Confidential transaction
Supporting pre-deal separation assessment across Finance and Technology, identifying what the future organisation will require to operate independently. The work considers CRM and ERP dependencies, Lead-to-Order and Order-to-Cash processes, application and licence separation, Day 1 requirements, standalone operating models, TSA dependencies, separation complexity and transition costs.
Pre-deal → Day 1 → Standalone
Post-Merger Technology Integration
Global Financial Institution
Led transformation within a global Treasury and custody environment following acquisition-led growth. The work included rationalising legacy technology, replatforming a 20-year-old custody processing environment onto a strategic global platform, and coordinating change across regions alongside major post-financial-crisis regulatory reform.
Integration → Simplification → Strategic Platform
Regulatory Separation & Legal-Entity Change
Global Bank
Led complex regulatory transformation spanning legal-entity separation, technology stand-up, client migration, operating-model change, regulatory readiness, cutover and go-live. Experience includes UK ring-fencing and Brexit-driven legal-entity transformation across Treasury and Credit businesses.
Separation → Migration → Go-Live
Treasury Transformation
International Development Organisation
Led a multi-stream Treasury and Finance transformation spanning technology, operating model, governance, business processes and organisational adoption, moving the programme from transformation design through implementation, go-live and stabilisation.

Transformation Operator | Finance, Treasury & M&A
I’m Yemi Oluseun, founder of The Change Hive. For more than 15 years, I’ve worked across complex Finance, Treasury, Technology and operating-model transformation — from global banks and international organisations to PE-backed technology businesses.
My work sits where strategy becomes execution: translating complex change into operating models, systems, processes and decisions that people can actually use.
I also created Continuity by Design, my ongoing work on how organisations preserve customer value, knowledge and capability through change. My doctoral research interest adds depth to this work, while client delivery remains focused on transformation.
The Change Hive is a founder-led practice. I lead client work personally and bring in trusted specialist associates where a mandate requires additional capacity.
