I don't understand this at all. It reads like PR boilerplate:

"Used by 99% of Stripes in the last month, Home is the source of truth for who we are, what we’re doing, and why—and a platform for enabling individuals and helping them get to know one another."

If it's the intranet/homepage/directory, of course everyone at Stripe uses it. If this is something worth talking about, let's dig into the real metrics around engagement and usage. It's strange to me to see a YC company so distracted by something this far outside of their core competency, especially to the point they would announce publicly all of the time and effort they put into it. This seems like a pure vanity project at best, and at worst evidence that Stripe is misdeploying resources as they scale, which happens and is often unavoidable.
