James Searby operates at the intersection of finance, law, and global arbitration—where numbers become narratives and valuation shapes outcomes. As an Affiliate Partner at Osborne Partners and Director at Separ Research Group, he brings two decades of expert witness experience across continents, advising tribunals on complex valuation, damages, and financial analysis in high-stakes disputes.
In this Christmas Special episode of The Koffee Conversation, James reframes expertise for the AI age: technical rigor with human judgment, independence over advocacy, and narrative clarity over numeric noise. His voice is precise yet accessible—making this conversation essential for professionals navigating arbitration, forensic finance, and cross-border dispute resolution.

James’s career journey was shaped by decisive “sliding doors” moments—from leaving Australia to study modern history and economics at Oxford, to choosing the UK over returning home, and later stepping into the expert witness world through Osborne Partners. Each pivot expanded his lens from pure analytics to context-rich judgment.
Over the years, he scaled leadership across FTI Consulting’s international arbitration practices in the Americas and Asia-Pacific before choosing boutique independence for depth over bureaucracy. A strategic move to Singapore catalyzed his independent testimony practice—aligning lifestyle with client impact while anchoring his work in integrity and objectivity.
