Amazon Alexa

As a special feature of this Hackathon, the Amazon Alexa team will be on site to teach teams how to create Alexa Skills for their apps. The Alexa Skills Kit is a collection of self-service APIs, tools, documentation and code samples that make it fast and easy for teams to add skills to Alexa.

A prize will be awarded to the team with the best Alexa UX.

Each participant will receive a generous SWAG kit from Capital One DevExchange for participating. We're also creating rewards for finishing at the top of each API and judging category as well as recognizing overall top finishers. It's an opportunity to show what you're capable of and gain recognition for yoursel and your team as fintech developers. 

Hackathon Teams

It takes all of us to build great software - developers, designers, product managers and business strategists. We all work together to deliver solutions that users love and tell all their friends about.

Hackathon teams are no different. Everybody plays an important part in the overall application – so join in the fun, even if you don’t code! If you don’t have a team, we’ll find you one where your skills are needed and you can let your freak flag fly.

Capital One Cafe

Here at Capital One®, we believe banking should fit your everyday life—not the other way around. That’s why we opened a cool new space for you in Denver: the Capital One Café in Union Station LoDo. It’s an inviting, comfortable place to get some banking done, enjoy tasty Peet’s® beverages and local snacks—or just hang out with some on-the-house Wi-Fi.


Who should attend the Capital One DevExchange Hackathon? (What if I’m new to coding, a designer, etc.?)

We welcome programmers, developers, product managers, designers, and entrepreneurs of all levels at the Capital One DevExchange Hackathon. In fact, the Hackathon is a great way to expand and improve your skills. A team with varied skill sets can collaborate to generate new ideas and solve problems.

Why should I attend the Capital One DevExchange Hackathon?

First of all, it’s fun! The event brings together talented people as well as experts from Capital One DevExchange and Amazon Alexa, and it offers an opportunity to learn a ton of new and exciting skills - all in one day. Of course, there will also be lots of food, prizes and awards for the top finishers.

What should I expect at the event?

The Hackathon will task participants to work with a team of fellow developers, designers, and product managers to build new apps using the Capital One DevExchange suite of APIs. In addition to CapitalOne DevExchange APIs, the Amazon Alexa team will be on hand to help teams integrate Alexa Skills into their apps. With resources to learn how to build Alexa Skills into new applications, and awards for the best integration of Alexa UX, this offers an opportunity to work with cutting edge voice control technology as well.
