The logos highlight companies where our customers (the engineers) work. Since we're early stage, so far it's more common for engineers to discover CodeCrafters, sign up by themselves, and expense it to their company. That might explain why you can't find information about subscription on the intranet.
We also do have cases where we work with companies to land team subscriptions, so if you'd be interested for us to engage with your company, feel free to drop me a note — sarup@codecrafters.io, and I'd love to help. It might be that the person you couldn't locate has moved on from the company, but I don't have a good explanation for why you couldn't find them on LinkedIn :-D If you emailed me, I could ask them and find out for you (for references, etc) — for most listed on the website, I've been in contact with them :)
