sponsors from "Who's using Debian?" page?

[kathey]

We might send sponsorship requests to people when we ask for updates to 
the "Who's using Debian?" page: https://www.debian.org/users/

That was a good idea from last week's meeting, but how should we do it? 
Most of the commercial listings have a company website, but no email 
listed. Before we go searching for email and contact forms one-by-one, 
anyone have other suggestions?
