Tandem is an AI powered knowledge layer for mechanical design. We plug into CAD and the surrounding tool stack to capture what changed, link it to the intent behind it, and use that context to keep teams aligned on requirements, reviews, and compliance

Kunal, Arjun, Lohit, and Lokesh left Boeing, Rolls-Royce, AWS, and Google to build Tandem around four core modules:

1. Watch
Records design actions inside CAD to build a feature-level timeline of edits and diffs that can be replayed, summarized, and used for audit trails.

2. Integration Layer
Connects to PDM, PLM, file systems, and tools like Outlook, Slack, and Teams so requirements, feedback, and review notes stay attached to the exact parts, drawings, and interfaces they refer to.

3. Requirements Workspace
Links requirements to CAD models, drawings, assemblies, and tests, then flags gaps and risk when geometry changes without updated coverage.

4. Assist
An interface inside CAD and the browser that answers questions like what changed since the last review, why an interface or tolerance was chosen, and what is now at risk, using the connected context.

Together, these modules turn scattered engineering artifacts into a living traceability graph and a proactive partner that catches issues earlier, speeds up reviews, and keeps teams audit-ready without forcing a new workflow.
