About Testunlimited

TestUnlimited is building the world’s largest marketplace for test and measurement products and services and serves buyers (engineering and supply chain teams) and sellers (OEMs, distributors, resellers, renters, etc.) of test and measurement products and services.

We help engineering teams to be test-ready for even the most challenging situations. We accomplish this by having the largest single source of inventory listings (new, used, rental, ex-demo) in the world and by having and outstanding platform that enables users to research alternative products, find inventory and pricing from many multiple suppliers, and submit requests for information/quote to over 50 suppliers simultaneously. More details here.

At the same time, TestUnlimited helps T&M makers, distributors, resellers, rental firms, and calibration/repair firms demonstrate how they make a difference for engineering and supply chain teams – and grow their business! More about how we do this here.


Our vision is to build a platform and community that plays a central role in helping engineering and supply chain teams develop outstanding products while also enabling outstanding test suppliers to thrive.

Values / Approach
Try, Measure, Adjust. We work together to find and select great ideas, take action, measure performance, make adjustments, and repeat -- every day. This process of creative experimentation is at the heart of what we are about.
Community. We believe in the power of working together toward common goals, in finding common ground, in win-win relationships. Integrity, communication, effort, grace, teamwork and talent are things we believe help build strong communities.
Make a Difference. We work hard to make a positive difference in the daily lives of everyone involved in TestUnlimited – from engineers, to buyers, to company owners/leaders, to sales and marketing teams, to everyone involved in building the TestUnlimited platform.
Fun. We find enjoyment in every day and help others do the same.
