Our Story

Alexandra & Nina become friends at their local Greek School in Boston

Alexandra has a valentine making night at her apartment in Chicago, and everyone stayed late making cards, sparking the idea that this type of event would be one to continue.

Alexandra brings the idea to a local coffee shop, Sip of Hope, where the first official card making pop-up is hosted!

Nina joins the team and builds the website

Alexandra tries out the idea of an in-flight pop up 

Stamp of Sunshine x Starbucks collab for week of kindness

1,000 cards sent by Stamp of Sunshine pop-ups!

SoS becomes a non profit organization (& co-founders run 13.1 miles to celebrate!) 

Stamp of Sunshine turns 1! & becomes tax exempt with the IRA 

Nina & Alexandra each host a pop-up in their cities (Boston & Chicago) to celebrate the 100th pop up!!
