our users and our users users.

We needed a calendar widget ourself!
It all started in 2012 in a small office space in Palo Alto. We needed an
"Add to Calendar" widget for a customers website but we were not able to find a great source. So we had to build it ourself. Since our launch AddEvent has grown rapidly. We have been amazed in experiencing how many people and organizations trust our service. Ranging from small companies to fortune 500 companies. Wow!
