About AddEvent

Our mission is to build the best
calendar solutions in the world.

Our tools help businesses large and
small manage and share their events.

AddEvent was founded in 2015 when our founder realized the importance of calendars in peoples’ everyday lives. We built and released the world’s first “Add to Calendar” button, user growth exploded, and we never looked back.

Today, AddEvent is a rapidly growing technology company located in the heart of Silicon Valley, California. We offer a suite of powerful calendar management and marketing tools that are used by many of the largest companies in the world.

You deserve a better calendar experience.

We couldn’t find a good “Add to Calendar” button back in 2015, so we built our own and shared it with the world.

We've expanded our range of services since then and we're just getting started. We still ground ourselves every day in building incredible and simple to understand tools that solve concrete problems, and the best part of our jobs is still getting to share our creations with you.

From product design to user experience to customer service, we believe you - and your users deserve the very best. Our team is committed to providing you with an unparalleled experience at every step of the way.

We’re driven by our values 💪

Ownership mentality.

Every employee has the power to make our company better.

High quality only.

This is our craft. We create solid, high-quality products that are built to last.


Teammates, customers and yourself. Respect costs nothing but means the world.

Go the extra mile.

Go beyond delivering what works. Discover what delights.

Do what’s right.

What is right isn’t always the same as what is easy.

Be transparent.

Share information, mistakes, and victories. Be honest.

We’re making sure your
events reach your users’ calendars.
