Their work powers the insights companies and auditors rely on for decision-making and transparency.
 * AI Systems - Develops Ledgy's AI foundations and product experiences, from AI agents and AI-assisted workflows to the platform capabilities that help other teams embed AI safely in their domains. The team works in a new and evolving product area, balancing rapid iteration with reliable execution, evaluation tooling, and responsible automation.
 * Tax - Ensures taxes are correctly reflected throughout equity operations, especially moments such as exercising, selling, mobility, and other taxable events. As a future team, Tax will build end-to-end product capabilities across the stack, helping customers manage complex tax and compliance requirements accurately across jurisdictions., We have a modern, cohesive stack that lets us move fast while maintaining quality:
