🎂 It's @sophie's birthday! Drop your favorite memory — let's make her feed ridiculous today.

The Slack birthday bot that automates birthdays, work anniversaries, and team milestones — no spreadsheets, no calendar reminders, no missed moments.

Set it once

Two minutes to install. Then never think about birthdays again.

Build a team people stay for

Consistent recognition is what separates teams people leave from teams people brag about.

Be the one who remembers

Warm, personal shout-outs land in Slack and your team feels seen.

The difference your team feels

“Fine” isn't a feeling anyone remembers.

Forgettable shout-outs are almost as bad as no shout-out at all. Your team deserves better.

Never a missed birthday.
Never an anniversary.
