Never missa single milestone.
Cake Day posts warm, personal shout-outs in your Slack — every birthday, every work anniversary, every year. You never have to remember a date again.


The Slack birthday bot that automates birthdays, work anniversaries, and team milestones — no spreadsheets, no calendar reminders, no missed moments.
Two minutes to install. Then never think about birthdays again.
Consistent recognition is what separates teams people leave from teams people brag about.
Warm, personal shout-outs land in Slack and your team feels seen.
“Fine” isn't a feeling anyone remembers.
Forgettable shout-outs are almost as bad as no shout-out at all. Your team deserves better.




(Fine. Forgettable. Forgotten by lunch.)
(Warm, personal, and never the same twice.)
Recognition that actually lands.
From brand-new hires to 10-year veterans — every teammate gets a warm, personal moment their whole team can rally around.
