fieldguide.io LinkedIn

Fieldguide builds an AI-native platform for audit, advisory, and assurance firms, deployed across a mix of Big Four and mid-market practices. The tech stack is heavily weighted toward AI infrastructure (OpenAI, Anthropic, Gemini, LangSmith, LangGraph) and real-time data orchestration (Apache Airflow, PostgreSQL, GraphQL), reflecting a core bet on agentic automation for complex audit workflows. The hiring mix—17 engineers, 12 sales, and a director-level leadership layer—signals a company scaling post-Series C while managing the friction of moving legacy-tool users into a new platform paradigm.
