Codex – CBS’s startup that helps you sell your old books

1. Could you explain what Codex is, and how it works? 

Codex_S3Codex is an iOS app that simplifies the process of either buying or selling used student textbooks. In the app, we only initiate contact between buyer and seller meaning there’s no financial transactions going on.

We’ve put a great effort into limiting the number of steps needed for putting a textbook up for sale. Simply put, you’ll scan the barcode of a chosen textbook, and we’ll display all the books information for you to review and/or change.

After doing so, you may type in a selling price or use the one that is already suggested for you. Buying a student textbook is also very easy – quickly search and find the book you need after which it’s easy to initiate contact to the seller via direct messaging inside the app.



2. Who are the people behind the Codex? (Your roles, background etc.) 

We’re three people involved in creating Codex: Anders, Silas and Budi.

Silas and I will graduate from CBS this year, and Budi is already out there exploring life after university.


3. Why did you start Codex? 

Both being students, Silas and I have thought of either buying and/or selling used textbooks as a way to reduce costs at the start of each semester. However, we haven’t seen any services that offers a truly hassle-free experience – partly because every current solution is made for desktop. As we combine the use of an iPhone’s camera to scan a textbook’s barcode with automatically retrieved information about the book, you’re really just a few seconds away from displaying the book on our platform for potential buyers to find.


4. What barriers have you overcome to realize the idea?

To be honest, we’ve had no significant barriers to overcome from a technological standpoint. Part of which makes Codex a great alternative to current services, is the fact that scanning a barcode with the camera of an iPhone is not only doable, but easy and consistent. After prototyping this part of the app, we knew we could make something great.

More importantly though, in order for Codex to be meaningful in any way, it has to gain traction among a significant number of students here in Denmark. As we’ve launched during a semester, we’re trying to polish the app as much as we can while trying to “get the word out” before September.


5. What are the future plans for Codex? (goals, visions, updates etc.) 

In order for Codex to become the “go-to” marketplace for buying and selling used student textbooks, we’ll be doing small incremental changes to the app while also squishing out bugs along the way. An example of such is the next update that’ll be available on App Store next month – this particular version of the app adds the  possibility for a seller to specify the condition of the book he’s selling and whether this book contains annotations.

About the Author :

So you want to know something about Nick? But be careful, he is a charming bastard. But okay, here we go: Nick Christiansen was born in a small town outside the fishing capital of Denmark (Esbjerg), ironically he is allergic to fish, so he had to move to Copenhagen! He loves entrepreneurship, meeting new people, good stories and all the other good parts of life. If you want to find Nick, you should start at the entrepreneurship events around Copenhagen, or at the best pizza places in Frederiksberg, just look for a guy in yellow pants, tank-top or something similar. That was enough about Nick for now, but if you want to know more, try to dance and talk to him at Nexus, because he has got some sick moves…
