Tandem does powerful work in a really simple way

All within an enterprise-grade secure environment.

Simplify collaboration for everyone.

Design, manufacturing, and suppliers often work with half the story. The result? Misaligned parts, costly scrap, and endless rework.

Preserve and Leverage Tribal Knowledge.

When engineers walk out the door, their know-how goes with them. Context hidden in emails and conversations vanishes, leaving teams guessing at past decisions.

Turn Design Into Documentation

Engineers skip docs because they’re slow and painful. That means missing rationale, patchy records, and hours wasted chasing lost intent.

What Our Users Are Saying

At Tandem, we understand your engineering data so you can ask questions about it.

30+ Companies Waiting

  • Every time I look at an old part, there's always something off, wrong descriptions, bad file names, or no clear build order. I end up digging through the model tree just trying to figure out what someone else did. And if things aren't labeled clearly, it becomes a guessing game. Change one feature and suddenly everything downstream breaks.

    Kyle Suh

    Mechanical Engineer @ Johnson Controls

  • I love to design for customers. But every review turns into proving I followed the rules. That's not why I became an engineer. If Tandem can take care of that, it's a game changer

    Andrew Shutte

    Largest SOLIDWORKS User Group Leader

  • The documentation needed in decision making is painful to find and create. So if you guys can hit that, that would be like a major quality of life improvement.

    Todd Mansfield

    Director of Product @ OneIPM, Ex. COO of House of Design Robotics

  • "I never wanted to be a clerk. I wanted to be an engineer. Tandem gives that ability"

    Jim Doxey

    PDM Professional Ex. Google, FB, Oculus, Boeing

  • Our change process is fully manual. We fill out forms by hand, list part numbers and revisions in spreadsheets, paste them in PowerApp for approval. Writing up the rationale takes time and usually comes from scattered discussions. It's slow and easy to mess up.

    Odell Jimenez

    Product Development Engineer · NIBCO INC.

  • Everyone in the CAD review are not looking at my file every day like I was. Having Tandem would be amazing, Asking Tandem what the part is, why it's there, would help speed the design review. It shifts the review from just nodding along to real idea generation.
