Creating great experiences

Founded in 2011 and headquartered in Copenhagen, Clerk.io is founder-owned, profitable, and in this for the long-haul.

We believe that a truly great AI should be able to get the job done by itself and not take up your valuable time with constant tweaking or meetings with developers and consultants.

That's why we built Clerk.io to help your customers discover your products, allowing you to create great shopping experiences while also focusing on creating new growth for your business.

We come to work every day to make life better for you, your customers, and our colleagues.

We originate from E-Commerce ourselves


Clerk.io is deeply influenced by my time at Unisport in it's early growth days, where we took the company from a small 4-person team into the innovative e-commerce giant it is today.

One of the recurrent problems was making our products easy to find for our customers. No matter what software we bought (or built ourselves), we always ended up spending hours tweaking and making adjustments every month.

There is no growth killer like time-consuming manual work!!

So combining my e-commerce experience with my background in computer science, I created Clerk.io to be the opposite of all that- a tool that makes products easy to find for the customer while requiring no maintenance for the store owner.

That's good for both the top- and bottom line.

We believe companies should do more

We believe that companies have a bigger purpose than just serving customers, engaging employees, and enriching shareholders. We believe that companies should actively improve their communities and the world.

That's why we support charities that improve our community, help people less fortunate than ourselves, and protect our planet.

These charities are chosen jointly by all employees of Clerk.io.

Work in a company loved by customers

We go to work every day to make our customers successful and happy.

We're looking for smart, enthusiastic, and skilled people to help us make online shopping easy.


I love Clerk.io! <3 As a smaller, but growing, e-commerce shop in Denmark, Clerk.io has been one of our most important partners as they today really affect half of all our orders, which is pretty amazing. Their product recommendations raise our average basket size by now 22%!

There are the companies that you have to work with, and then there are those who you love to work with. Clerk.io definitely belongs to the latter.
