Achievers

  • 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

  • Requires dedicated video conferencing service for formal meetings and webinars
