Role overview
Caribou is a tax technology company that specializes in transfer pricing solutions for multi-entity and globally expanding companies, with a particular focus on SaaS and other high-growth businesses.[4][3] The platform helps organizations scale internationally without overpaying tax or relying heavily on traditional Big Four tax consultants by automating key aspects of transfer pricing compliance.[3][4] Caribou generates and maintains intra-group agreements, transfer pricing policies, and benchmarking analyses to align intercompany transactions with international tax regulations.[4][2] It creates intragroup agreements, intercompany loan documents, and licensing contracts between entities, and monitors changes in group structure so that documentation stays up to date.[2] The system also supports preparation of local and master file documentation, benchmarking studies, and accounting implementation to meet OECD and other transfer pricing documentation requirements.[2] In addition, Caribou offers ongoing access to tax experts (e.g., via Slack or Teams) and integrates into a broader finance and tax stack through a vetted partner network, providing a comprehensive, software-enabled alternative to traditional transfer pricing advisory services.[2][7]
