It's basically a place to distribute information about them.
* ethnically diverse happy people stock photos (80% of the page content)
* carousels and pages with vague two sentence statements and a link. Link leads to missions statements and values and maybe a short paragraph.

I get it's expected in the B2B "we sell to idiot VPs" world, but jesus... have at least one page somewhere with a tech stack and platform summary.
