About
A specialist in network test and measurement
Glean Co. builds its own testing tools and sources, evaluates, localizes, and supports the world's leading test products for network engineers in Japan and beyond.
We make network behavior visible
Network problems are hard because they're invisible. We make them visible across five disciplines: capture, analysis, measurement, emulation, and testing, spanning packet capture, 5G, voice and video quality, and load testing, all in compact, professional-grade tools.
We design and develop several products in-house, including the ToyCap capture series, VoicePinger, and ToySIM. Alongside them, we partner with leading international vendors to bring their test platforms to our customers, evaluating, localizing, and supporting every product we carry.
Why “Glean”
The name reflects how we work. To glean is to gather carefully, piece by piece. We glean information from our customers and suppliers, analyze the technical requirements in detail, and identify the optimal, low-cost solution.
