You cannot buy the INVEST hat.
We give them away for free to members of our community who participate in productive conversations, share ideas, and uphold our values of transparency and respect.
We also sometimes give them away on Twitter as part of flash giveaways, or to random people who tweet us and ask (nicely).
If you love the hat and want one, join our community and send us a tweet via this site: https://public.com/invest-hat
If you ever have questions, the team is always here for you, so feel free to give us a shout on the app’s Live Chat or via email at firstname.lastname@example.org! 😁
