Slightly off topic: this quote from the SEC filing document:

"Immediately prior to the completion of this offering, we intend to change our corporate form from a Dutch private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) into a Dutch public limited company (naamloze vennootschap) and change our corporate name from Elastic B.V. to Elastic N.V."

As far as I know, Elasticsearch has no headquarters or offices in The Netherlands. I assume the company is only registered in The Netherlands for tax avoidance.

If my assumption is true, despite that I like their products, this makes me a little sad.

EDIT: my bad. I missed the tab Europe and Asia. They do seem to have an office in Amsterdam.
