Welcome to AddEvent New


Welcome! This article is a great place to start if you’re new to AddEvent. We’ll briefly cover who we are, what we do, and who our customers are. Enjoy!

Who are we?

Great question. AddEvent is a rapidly growing technology company located in the heart of Silicon Valley, California. We create powerful calendar management and marketing APIs that are used by some of the largest companies in the world (hint: check out our website home page for a list of the biggest).

It all began back in 2012 when Michael Nilsson (AddEvent’s founder and one of Denmark’s most talented developers) started creating API’s for adding events to personal calendars. It turns out there was a huge need for these tools and new user growth exploded. Michael incorporated and in 2015 moved his newly founded company from Denmark to Silicon Valley.

What do we do?

AddEvent is the #1 Add to Calendar service on the internet. At the most basic level, we give companies a way to get their events on their customers’ personal calendars. We do this through a proprietary calendar management ecosystem of 5 different API services that allow businesses to utilize their customers’ personal calendars as a new method of customer engagement and marketing. AddEvent’s APIs can be integrated seamlessly into businesses’ websites, email campaigns, applications, and digital marketing services, and work with all major calendar applications.

But wait, what are the actual APIs? What do they do?

If you’re asking this question, you’re in luck, because we’ve published a series of docs that take a deep-dive into our APIs. Each doc clearly explains a different API tool, including what it is, how it works, and the concrete impact it can have on your business. If you want to get started, you can find these docs here.
