The Open-Source Onboarder: Build a Thriving Remote Culture from Day One

In a remote-first world, your new hires are joining from their homes, not your office. This physical distance often creates emotional distance, leading to isolation and a weak connection to your company's culture. Without natural 'water cooler' moments, they struggle to build relationships and truly feel like they belong, risking lower morale, poor collaboration, and ultimately, higher turnover.

The Open-Source Onboarder playbook tackles remote isolation head-on by creating a structured yet social onboarding experience, all with zero software licensing costs. We use a visual Trello board to transparently track every onboarding task, from HR paperwork to scheduled 'coffee chats'. All communication is centralized in a self-hosted Mattermost instance for a secure community hub, and we leverage the open-source Jitsi Meet for interactive workshops and virtual meet-and-greets, ensuring your new team members feel seen, heard, and integrated from their very first day.

Expected Outcomes

  • Increased new hire engagement and faster time-to-productivity.
  • Stronger social connections between new employees and their teams.
  • Improved integration into the company's unique culture and values.
  • Reduced feelings of isolation for remote employees.
  • Higher long-term employee retention and improved team morale.
  • Maintained data sovereignty with zero software licensing costs.

Integration Logic

  • Mattermost Webhook for Trello

    This integration is powered by a Mattermost plugin. The user installs and configures the Trello plugin within Mattermost, authenticating with their Trello account. They then create subscriptions within specific Mattermost channels, linking them to Trello boards and selecting which events should trigger a notification (e.g., card creation, movement, comments). When a subscribed event occurs in Trello, it sends a webhook to the Mattermost plugin. The plugin processes the data, formats it into a user-friendly message, appends a dynamically generated Jitsi Meet link for the specific card, and posts the complete notification to the designated Mattermost channel.
