Brewster Kahle, the IA's founder, did. It is called Alexa Internet, and was sold to Amazon:

<https://help.archive.org/help/wayback-machine-general-inform...>

A condition of that sale was that Alexa would continue to provide the results of its crawls, after a delay, to the Internet Archive. Those crawls form a substantial portion of IA's Wayback Machine archive.

I'm not certain that those archive are ongoing, as Alexa seems to have been largely shut down.

IA are a bit cagey on details, but I believe that there is a general IA-based archival service. There's certainly the "Save Page Now" feature:

  https://web.archive.org/save/<URL>

And the independent but closely-cooperating ArchiveTeam (lead by Jason Scott) tailors crawlers specific to endangered / vulnerable online websites, its Warrior software:

Interesting, from a consumer's perspective I never liked Alexa. But from a hoster's perspective it was awesome. Especially when you're in the top 1000. It helped my site get more popular.
