Coding at the speed of design

thirteen23 takes an agile approach to design. Throughout our design process, we are constantly validating, prototyping, and testing to make sure our design solutions are actually doing what they’re supposed to. It's a handy process, one that allows us to create UI solutions that can be easily leveraged across development teams with minimal loss in design fidelity. We do it to make sure that even when we pull our hands back, everything still runs smoothly.

One team, every time

The team you meet at the sales meeting is the team that works on your project. We like consistency.

Which is why we’ve composed a staff of handpicked industry professionals whose resumes boast lots of big awards, some smaller ones, and two we’re pretty sure were just made up. Between the lot of us, we’ve managed to work with some of the most influential companies in the world.


Time is scarce in the design world, so in an effort to prolong the workday, our founders decided to create a 13-hour clock. It looked just like a regular clock, but with a tiny 13 wedged between the 12 and 1. After realizing that this new timescale didn’t add an hour so much as simply eliminate the 12 o’clock hour, the founders worked themselves into a frenzy, fearing that their eagerness to gain some time had actually resulted in a noonless, 23-hour day. The name thirteen23 is in reference to the fact that, no, it didn’t.

Great design requires great people.

Despite what our business cards say, everyone at thirteen23 is a designer. We each have our own unique talents, but our bread and butter is the magic that comes of tight collaboration between strategy, design and development.

We don’t care if you’re fresh out of school or already have a decade of experience under your belt – we want creative perfectionists, people who are detail-oriented, want to get it right, and understand the reality of shipping a product. If this sounds like you, let’s talk!
