Dunno I am not administrating it so I didn’t checked. We got the sponsorship tiers as a lemmy/piefed instance is an open source project https://zulip.com/help/self-hosted-billing#free-community-plan

I believe Rimu (piefed dev) also got the sponsorship.

I plan on using it for personal business projects (self hosted or not, it is not defined yet) to organize comms and plans in topics. But it’s a small team of way less than 10 and if it grows bigger than that it will means we have du money to upgrade (it won’t be eligible for sponsorship tho).
