This is why 1 year ago we open sourced[0] SpiceDB[1] under Apache2 and have been leading the way for open source Zanzibar systems. SpiceDB has contributors and users from the likes of GitHub and Adobe in addition to Authzed; building in the open and making sure that we aren't the only ones supporting SpiceDB is critical to the long term success of our users and our business.
This is awesome, but it's also kind of wild that YC basically put closed-source and open-source competitors in the same space in virtually the same batch.
I'll definitely be looking at this for my current project.
