Wikipedia:Articles for deletion/Tosca (software)
The existing article is a bit of a mess, but it's clear that folks have tried to source the statements.  There are some not-too-unreasonable  trade-rags buried in the current refs for the article.  I suspect more such  exist, for somebody that speaks German and works in Austria/Switzerland/Germany where the company does most of their business.  The ones I found below are new, from what I can tell
— NONE, NONE
