We hope it’d be before then, but it’s impossible to forecast these things. 
An honest self-assessment of the situation today: Anytype is only suitable for small teams. However, as mentioned in this reddit post and as seen in our latest roadmap, we are actively prioritising features for organisational usage. This ranges from user management, authorisation, integrations, etc. Beyond that, we’re also working on essential areas such as reminders, object discussions, general stability, performance, and quality-of-life upgrades.
In our own dogfooding (our own team using Anytype), we’ve been able to fully deprecate Slack and use it as our primary communication and knowledge base tool. However, it does have its pains.
