In October of 2006, Leonard Rosenthol (the owner and Chief Technology Officer of PDF Sages), was hired by Adobe Systems as a PDF Standards Architect focusing on the development and promotion of international standards for PDF. At that same time, PDF Sages stopped conducting business.

If you are looking for the software products developed by PDF Sages, they continue to be sold and supported by Apago. Contact them for PDF Enhancer, PDF Appraiser, PDF Constructor and others.

If you are in need of custom software development, I recommend the following companies.

If you are in need of PDF consulting services, I recommend Thom Parker of WindJack Solutions who subcontracted with PDF Sages on a number of projects.
