Joseph Hage Aaronson & Bremen is a London-based dispute-resolution practice built on a hybrid model of barristers, solicitors, forensic accountants, and data scientists. The firm's tech stack is almost entirely Microsoft Azure and Microsoft 365—with recent adoption of Azure OpenAI and Azure Cognitive Services—paired with active projects around automation and monitoring. This signals a shift toward internal operational efficiency (reducing repetitive tasks, streamlining workflows) rather than client-facing product innovation, supported by an engineering hire and accelerating recruitment velocity.
JHA specializes in high-value commercial litigation, tax disputes, HMRC disputes, arbitration, insolvency litigation, and forensic investigation across the UK and internationally. The firm operates as a partnership with 51–200 employees, founded in 2013. Beyond traditional legal counsel, the practice integrates forensic accountants and data scientists into dispute teams to develop practical and commercial solutions. Current internal priorities center on process automation, proactive tax planning in response to legislative shifts, and managing increasing client demand for cross-border tax structuring advice.
The firm runs almost entirely on Microsoft cloud: Azure (compute and AI services), Microsoft 365 (Exchange, Teams, SharePoint, OneDrive), Office apps, Power Platform (Power Automate, Power Apps), and Active Directory for identity. Recent additions include Azure OpenAI and Azure Cognitive Services.
Active projects include automation solution development, intelligent automation integration, monitoring and alerting, process optimization, and tax planning updates responding to legislative changes. Internal challenges center on eliminating repetitive tasks and streamlining workflows.
