and JFrog (I don't know anything about them, but the S-1 was posted on HN today).
And AirBnB is much earlier in the process but has filed confidentially.
If Airbnb filed their S-1 last week, and these companies filed their S-1s today, then wouldn't Airbnb be further along in the process and not "much earlier"?
They filed confidential paperwork - the actual public S-1 will come months later. E.g. Asana had confidentially filed back in February.
