Birthdays are better together
Group texts get messy. Cards get forgotten. Everyone means to send something and it gets lost in the noise. Kudos Moments gives one link, one place, and one moment when it all comes together.
One link, no coordination — no group chats, no reminders you have to send yourself.
No account required to contribute — the easier it is, the more people actually send something.
Sealed until it matters — nothing leaks early, nothing gets spoiled.
