The short version

  • Each has a real cost: Kumospace reporting from late 2025 described the team as having shrunk to roughly eleven people with the chief executive publicly listed as leading a separate company, so continuity is a genuine question and should be checked before a multi-year commitment.; Slack 90-day message history limit on free plan results in important conversations disappearing
  • They diverge on capability: Kumospace covers Proximity audio and video, Slack covers Channels.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kumospace

  • Reporting from late 2025 described the team as having shrunk to roughly eleven people with the chief executive publicly listed as leading a separate company, so continuity is a genuine question and should be checked before a multi-year commitment.
  • Product development has visibly slowed against the category; capabilities that rivals now treat as standard, such as an AI note taker and asynchronous video, are absent.
  • Leaving a spatial office open all day means continuous audio and video connections, which is heavier on laptop battery and bandwidth than an occasional call and is a real complaint from users on poor connections.
  • The free tier caps at five registered members, which is below the size at which a spatial office starts to be useful, so evaluating it properly requires paying.
  • Adoption is behavioural, not technical: teams that do not build a habit of being present in the space get nothing from it, and the licence quietly becomes an unused cost that shows up at renewal.

Slack

  • 90-day message history limit on free plan results in important conversations disappearing
  • Per-user pricing becomes expensive quickly for larger teams
  • Notification overload with 78% of employees feeling overwhelmed by notifications
  • Mobile app performance issues including lag and slow syncing
  • Huddles limited to 50 people and cannot be recorded
  • Requires dedicated video conferencing service for formal meetings and webinars
