ABOUT PRINCIPLED TECHNOLOGIES 
We provide industry-leading technology assessment and fact-based 
marketing services. We bring to every assignment extensive experience 
with and expertise in all aspects of technology testing and analysis, from 
researching new technologies, to developing new methodologies, to 
testing with existing and new tools.  
When the assessment is complete, we know how to present the results 
to a broad range of target audiences. We provide our clients with the 
materials they need, from market-focused data to use in their own 
collateral to custom sales aids, such as test reports, performance 
assessments, and white papers. Every document reflects the results of 
our trusted independent analysis.  
We provide customized services that focus on our clients’ individual 
requirements. Whether the technology involves hardware, software, 
Web sites, or services, we offer the experience, expertise, and tools to 
help our clients assess how it will fare against its competition, its 
performance, its market readiness, and its quality and reliability. 
Our founders, Mark L. Van Name and Bill Catchings, have worked 
together in technology assessment for over 20 years. As journalists, 
they published over a thousand articles on a wide array of technology 
subjects. They created and led the Ziff-Davis Benchmark Operation, 
which developed such industry-standard benchmarks as Ziff Davis 
Media’s Winstone and WebBench. They founded and led eTesting Labs, 
and after the acquisition of that company by Lionbridge Technologies 
were the head and CTO of VeriTest.
