Or speak at our virtual GristCon in October? It's a community event where most speakers are Grist users, all on Discord stages. Very fun.
I'd love to connect with them. If they're open, they can reach me at: success [at] getgrist [dot] com
Disclosure: I'm CEO at Grist.
By the way, Grist is Airtable-like and has RBAC down to every row and cell, enforced live. And you can self-host it. Check it out: https://www.getgrist.com/airtable-alternative-self-hosted/
(FYI, I work at Grist.)
It brings over column types, references, attachments, and simple formulas intact. Even brings over choice/select colors!
Grist has access rules which give the document owners the ability to set rules that limit who can see or edit what, down to each table, column, or cell. Rules can be based on user attributes, including attributes defined by the document owner (e.g. roles within a company), and based on values in cells (e.g. if a row's boolean field is true or false).
