15Five + Slack
Connect 15Five and Slack to Build a Culture of Continuous Feedback
Automate performance management workflows and get real-time employee engagement insights directly inside Slack.
Why integrate 15Five and Slack?
15Five and Slack are two of the most widely adopted platforms in people-first organizations — one handling structured performance management, the other running daily team communication. When the two operate separately, check-in reminders go unnoticed, recognition gets buried in dashboards, and managers miss early signals about how their teams are doing. Connecting 15Five with Slack through tray.ai brings performance conversations into the flow of everyday work.

Use case
Automated Weekly Check-In Reminders
When a new 15Five check-in cycle opens, tray.ai sends a personalized Slack DM to each employee reminding them to complete their weekly reflection. The message includes a direct deep-link to their 15Five check-in, cutting the friction that kills completion rates. If a check-in is still missing past a configurable deadline, the reminder escalates to their manager.
Use case
High Five Recognition Posted to Team Channels
When an employee receives a High Five in 15Five, tray.ai posts a celebration message to a designated Slack channel — #recognition or the team's own channel. Peer-to-peer recognition reaches a wider audience instead of sitting quietly in a dashboard. Custom message formatting keeps the post feeling native to Slack.
Use case
Manager Alerts for Low Pulse or Wellbeing Scores
When a 15Five pulse or wellbeing score drops below a defined threshold, tray.ai sends a private Slack notification to the relevant manager, prompting a timely 1-on-1 conversation before things get worse. Alerts can also route to HR business partners for cases that need escalation.
Use case
OKR and Goal Update Notifications
When employees update OKR progress or complete a goal in 15Five, tray.ai posts an update to the relevant team or project Slack channel. The whole team stays current without anyone needing to log into 15Five separately. Managers get a scheduled digest of their direct reports' goal activity.
Use case
New 1-on-1 Agenda Item Notifications
When a direct report adds a talking point or question to an upcoming 1-on-1 agenda in 15Five, their manager gets an instant Slack notification. Managers can prepare thoughtful responses in advance instead of reading the agenda cold. Employees know their input landed.
Use case
Review Cycle Kickoff Announcements
When a performance review cycle launches in 15Five, tray.ai sends a structured announcement to designated Slack channels covering deadlines, expectations, and links to relevant resources. HR teams can customize the message and target specific departments. Follow-up reminders go out automatically as deadlines get closer.
Use case
Slackbot Prompt for Outstanding Manager Reviews
When an employee submits their 15Five check-in but their manager hasn't responded yet, tray.ai sends the manager a Slack reminder to complete their feedback. Employees don't have to wonder if their reflection was read. If reviews sit too long, escalation logic can notify HR.

15Five & Slack Challenges
What challenges are there when working with 15Five & Slack and how will using Tray.ai help?
Challenge
Low Check-In Completion Rates Due to Context Switching
Employees spend most of their day in Slack and often don't make it over to 15Five to complete their weekly check-ins. Participation drops, and the performance program loses value before HR even notices the trend.
How Tray.ai Can Help:
tray.ai sends timely, personalized Slack reminders with direct deep-links to each employee's 15Five check-in, removing the friction of switching tools and improving completion rates without manual HR follow-up.
Challenge
Recognition Stays Hidden Inside 15Five
High Fives awarded in 15Five are only visible to users who log in to the platform. Most don't. That limits the cultural impact of peer recognition and quietly reduces the incentive to give it.
How Tray.ai Can Help:
tray.ai mirrors 15Five recognition events to Slack channels in real time, so High Fives get celebrated publicly in front of the whole team rather than sitting unread in a dashboard.
Challenge
Delayed Manager Response to Employee Distress Signals
Low pulse scores and concerning check-in responses can sit in 15Five for days if managers aren't actively checking the platform. By the time someone notices, an at-risk employee has already felt unsupported for too long.
How Tray.ai Can Help:
tray.ai monitors 15Five scores in real time and sends immediate, private Slack alerts to managers when thresholds are crossed, giving them a chance to reach out before the situation gets harder to address.
Challenge
Manual HR Effort to Communicate Review Cycles
HR teams spend a surprising amount of time manually drafting and sending communications around review cycle launches, reminders, and deadlines. It's repetitive, easy to get wrong, and nearly impossible to personalize at scale.
How Tray.ai Can Help:
tray.ai automates the whole review cycle communication workflow. When a cycle launches in 15Five, structured Slack announcements go out automatically, and staged reminders fire as deadlines approach. No one on the HR team has to remember to send anything.
Challenge
No Closed-Loop Accountability for Manager Check-In Responses
Without automation, there's no reliable way to confirm that managers are actually responding to employee check-ins on time. That erodes employee trust and makes the 15Five program feel like a one-way street.
How Tray.ai Can Help:
tray.ai tracks submission and review status across 15Five check-ins and sends Slack nudges to managers with outstanding reviews, keeping the feedback loop closed without HR having to chase anyone down manually.
