About CoLab
At CoLab, we help mechanical engineering teams bring life-changing products to market years sooner.
CoLab is a cloud based platform purpose built for fast, effective design review. Using CoLab, multiple engineers, designers, and other stakeholders can review designs together and build off one another's feedback. Engineers at companies like Ford, Komatsu, and Johnson Controls use CoLab to review designs faster, prevent mistakes, and build the next generation of innovative products.

Frequently cited statistics show that people who identify with historically marginalized groups are likely to apply to jobs only if they meet 100% of the qualifications. We encourage you to help us break that statistic and apply even if you don’t meet every single qualification—your potential is what matters most to us.

What We Do
Engineers need better tools for working together. CAD and PLM systems aren’t built for the design conversations where collaboration truly happens. So engineers go outside of them, using emails and slideshows to get the job done. But when these critical design discussions live in siloed, manual tools, you’re missing vital insights on why engineering decisions are being made, what needs to improve, and how to steer your people in the right direction.
After struggling with the traditional email, PowerPoint, and screenshot-driven collaboration process used by over 90% of manufacturing teams today, our founders made a decision: if better tools didn’t exist, they’d build them. And so CoLab began.
CoLab is a web-based collaboration tool that lets your team share CAD, provide feedback with full mechanical context, and capture the critical design data that your other systems don’t—giving you a design review and collaboration process that’s standardized, simplified, and twice-as-fast.
Today CoLab is trusted by Fortune 500 companies like Johnson Controls and Hyundai Mobis, who use the platform to accelerate design cycles by 51%, drive continuous improvement, and reduce product costs and changes.
