Hi, I'm Karen

I make viral videos. My video Donut Selfie became the inspiration for the Beats By Dre #SoloSelfie global holiday campaign. I also learned to dance in a year and filmed my practice footage in a video with over 4 million views.

I'm the creator of Giveit100, an inspirational video progress site. Previously, I was the lead designer at the startup Exec and a product manager at Microsoft Excel.

Viral Videos and Work

Good Morning America calls it “the new selfie craze." (starts at 1 min 45s). It started with a video I made, Donut Selfie, which uses a technique where I'd swing my arm in a circle around my head (making a donut) with my iPhone. Beats by Dre decided to use it as the inspiration for their global holiday campaign, #SoloSelfie.

I’d wanted to learn to dance since I was a little kid, but didn’t start because I never thought I could get good. When I finally decided to learn, I filmed myself learning to dance over the course of a year. The video went viral, with 4 million views.

It’s been a crazy experience - I got to go on the Queen Latifah Show and have spoken and danced at conferences like Google I/O, TedX (watch video of performance), and Ignite. Here are my tips to learn how to dance and to make a viral video.


Giveit100 is a place for people to make inspirational progress videos from their practice footage. I got the idea for it after my dance video went viral, and built it with my co-founder Finbarr. Giveit100 has over 70,000 members with a combined 30 million video views. Some of our members have gone on to be featured in their own viral videos. Lakeisha’s 100 days at the gym and Estella’s 100 days of push-ups each have over a million views.

Awesome Baby Name

Awesome Baby Name is a baby name generator with an SEO twist: it finds unique names based on available domain names. Finbarr and I built it in a weekend at a hackathon. In just one week, over 100,000 people had tried it. The idea came from a joke - because I have such a common name, I couldn’t get karencheng.com. Finbarr joked that there should be a website that makes sure newborns never have this problem.


I was the lead designer at the startup Exec, where I learned to design and ship extremely fast. For my work there, VentureBeat called me "one of those rare startup Swiss Army knives who can seemingly do a little bit of everything: marketing, product, design, and beyond."

I designed two iPhone apps (Exec Errands and Exec Cleaning), the website, and all the marketing materials (everything from campaign emails to chocolate packaging). Exec sold to Handybook in 2013.

Microsoft Excel

I was a product manager for Microsoft Excel, where I led a team of 10 people to bring animations to Excel 2013. I made wireframes, ran usability tests, and got hordes of people to agree with each other on very long email chains and in conference rooms. I worked with developers to make sure the right features got shipped on time for an extremely complex product.

For my work on Excel, I have 9 patents pending. Oh - and I’m not the one responsible for the ribbon (that happened before I got there).


My specialty is designing and shipping - fast.
I'm a jack of all trades, perfect for a small startup.
