Grounded DI LLC
An answer should
stand up to questions.
Grounded DI LLC develops reasoning, verification, and execution-control architectures that connect AI-assisted work to its sources, governing rules, and authority to act.
Our purpose
Build the controls
into the work.
Consequential work needs explicit conditions for continuing, using a tool, or releasing a result. Grounded DI’s architecture connects those decisions to versioned rules, source checks, and a retained decision record.
The company develops the underlying methods and domain applications for legal, environmental, health, financial, engineering, and consumer work. Each field supplies its own sources, constraints, and review requirements. Application pages identify the relevant development stage and available records.
