However, given a little bit of digging into the redirects, I'm sure you can find them :)
Try doing an http GET request for the redirect, and see what appears in the Location.
You should be able to find a bit between that, and the SERPs themselves. (with a few seconds of work, I found a redirect for one of their Index Connect partners that had a url easily idenfiable by THAT companies domain name).
(side note: please refrain from mentioning individual companies names, keep it generic.)
