You might check out the work https://wristband.dev is doing on multi-tenant auth. My read is it's complimentary to what you're doing rather than competitive.

If you prefer an open source, and maybe more mature, alternative for multi tenant/b2b auth then have a look at https://zitadel.com (disclosure: work for zitadel)

Do they have an article that explains their approach? I couldn't get through the marketing-speak.
