Specialist Accounting and Finance Outsourcing for the Captive Insurance Sector

Bigtree was founded by captive insurance professionals who spent decades working with leading global organisations, including Aon, Marsh and Gallagher. Our founders and team members have supported captive operations across multiple domiciles, managed specialist finance teams and led complex projects in demanding, regulated environments.

That depth of experience gives Bigtree a practical understanding of the processes, controls, regulatory deadlines and quality standards that established captive managers and captive owners expect. We understand how captive finance functions operate, how jurisdictional requirements differ and how to build delivery teams that integrate effectively with existing operations.

Our industry experience shapes every aspect of our service — from client onboarding and process documentation to team structure, quality assurance and ongoing delivery. We combine specialist expertise with a disciplined approach: communicating our capabilities responsibly, protecting client confidentiality and not making unverified claims or implying formal partnerships without express permission.
