From Copilot to Colleague: Trustworthy Agents for High-Stakes - Joel Hron, CTO Thomson Reuters
Jul 23, 2025 · 19:45
Thomson Reuters CTO Joel Hron explains the shift from helpful AI assistants to productive, agentic systems in high-stakes legal, tax, and compliance workflows. He frames agency as a spectrum with dials for autonomy, context, memory, and coordination, which must be tuned to the risk tolerance of professional users. Key lessons include building the whole system first rather than over-indexing on minimal MVPs, treating legacy applications as assets to be decomposed into tools for agents, and the persistent challenge of evaluating agentic systems with expensive, variable human expert judgments. Hron demonstrates a tax product that extracts data from documents and maps it to a calculation engine, and a legal research agent that uses proprietary case law tools to produce cited reports. He emphasizes leveraging unique organizational assets—like Thomson Reuters' 4,500 domain experts and terabytes of proprietary content—to create differentiation.
