Tandem is the engineering data management platform for hardware teams. Companies building complex physical products use Tandem to manage their system architecture, track requirements, review 3D CAD models in the browser, and query their program data with an AI assistant.

How Tandem fits into your workflow

Tandem sits at the center of your hardware development process. It connects your system breakdown structure, requirements, CAD files, and team discussions into a single source of truth — so nothing falls through the cracks as your product evolves.

What you’ll find here

  • How to structure your product with the system architecture tree
  • How to manage and trace requirements across your program
  • How to upload and review CAD models without desktop software
  • How to use the AI agent to search, create, and update data with natural language
  • How to collaborate with annotations, live sessions, and design reviews

Capabilities

System architecture

Build your hardware breakdown structure with a drag-and-drop node tree. Track custom attributes on every system, subsystem, and component.

Requirements

Create requirement tables with custom columns, grouping, filtering, and traceability links. Import from Excel.

CAD and artifacts

Upload SolidWorks and STEP files. View 3D models in the browser, annotate drawings, and generate Bills of Materials.

AI agent

Ask questions about your program data in natural language. The agent can search, create, update, and analyze across your entire program.

Annotations and reviews

Mark up 3D models and 2D drawings with pins, shapes, and threaded discussions. Run formal design reviews.

Search

Find anything across nodes, requirements, documents, and artifacts with semantic search that understands meaning, not just keywords.

Why Tandem

  • Single source of truth — Architecture, requirements, CAD, and discussions live together
  • Browser-based 3D viewer — Review models without CAD licenses
  • AI-powered — Natural language queries across all your program data
  • Built for hardware — Designed for the complexity of physical product development
