Howdy, my name is Stephen Dafeng Ou!

In 2008, I moved from China to the U.S. at the age of 13. After teaching myself English, I've built a successful online business comprised of 8 popular web apps and worked as a programmer for companies worldwide. I spoke at TEDx about young entrepreneurship. When I'm not working, I am a photographer, cyclist, sports fan and mathemagician. Currently, I am a freshman at Stanford University.

Pat Flynn, Founder of Smart Passive Income

I'm currently not available for freelance work, but I can refer you to a developer!


You've already shipped an incredible number of products. How do you get ideas for your projects?

It's a simple 3-step process. 1. Pay close attention to things around you and find problems that annoy you. 2. Create the best solution to solve those problems. 3. Look for people with the same problems and promote your solution to them.

Double Your Freelancing Rate

What rate did you start out at? And what's the highest you've charged?

The first time I put out a price tag, it was $50 per hour. I pretty set that rate because I saw a post (I think it was on FreelanceSwitch) recommending the starting rate to be $50. At the peak, I charged $125 per hour for some specialized work. My public rate is $95 per hour.

A New Take

What are your long-term aspirations? What are your next steps?

It's my long-term goal to build a low-maintenance, high-return online business, whether it's a web app, a mobile app, an info product, a class, or all of them combined. I want to live comfortably while building something that solves a problem well and customers will pay for.


What advice can you give to other young entrepreneurs?

Marketing > coding. It is how businesses had been run for centuries, but it seems to change in the tech industry. If you want your business to be successful, you need to focus on marketing first. You need to communicate with customers. You need to generate leads. You need to get your pricing right.

SideProject Book

What advice would you give to a developer that is just about to begin a side project?

Focus on solving a real problem for people. There are so many misconceptions out there that you should always buy a domain and start writing code right away when you have an idea. From my experience, that never works. The process of idea validation is crucial to the idea's future success.


How do you bring ideas to life?

First, I validate the idea. I believe it's stupid to write a line of code without having someone willing to pay for it. Then I go to a whiteboard to sketch the idea. I plan out how each screen looks like, how they connect to each other, and improve them until they make sense. Then I'll go on a coding period when I write all the code as fast as possible.

The Startup Project

What is the most valuable thing you've learnt from the time you've been running startups?

Make your creations really good so that people want to talk about them. This is very powerful. When I made iTunes Instant, because people enjoyed it so much, they told their friends and blogged about it. And from this kind of word of mouth, it became insanely popular in short amount of time.

Raising CEO Kids

What have been the best surprises that you found in starting your business?

I found out recently that you don't have to be big to be successful. The common notion is you have to have a $xx millions company with #xxx employees to be successful. But that's not true. I will consider myself successful when I make $10k/month from a simple one-man lifestyle business.

Sawyer Speaks

What was your first entrepreneurial endeavor?

My first entrepreneurial endeavor is OneExtraLap. I started around November 2009. It was treated mainly as an experiment. It came along pretty well. Our small buy loyal group of users loved it. I just kept on developing what users requested, and at the same time, learning more and more about the world of programming and marketing.

Starting from the Bottom

“It’ll take at least four years for your English to catch up.” The verdict came from the owner of Kittie Land Tutoring Center. Looking out the window to an early September overcast, I prepared myself for an uphill battle ahead.

I came to the U.S. in July 2008, not knowing any spoken English. Eager yet naive, I immediately dreamed about starting a business in the land of entrepreneurship. However, I never realized the difficulty of overcoming the language barrier until the first day of school, when curious students bombarded me with questions like “What’s your name?” and “Where’re you from?” Embarrassingly, I couldn’t answer them, so I sat cluelessly in the last row while immature kids made fun of my thick glasses and outdated T-shirt. To make matters worse, I had no friends who could help me out.

I needed serious assistance. Soon, my family found a tutoring center called Kittie Land. They offered one-on-two English training at a hefty price, but we had no choice. Before we signed the contract, the owner told me, “Even with a daily two-hour session, it’ll take at least four years for your English to catch up.” I promptly activated my mental math machine and figured out how much I’d be spending my parents’ hard-earned money in the next four years. Feeling guilty yet desperate, tears dropped from my eyes for the first time in seven years.

Things didn’t make an upward turn. As the owner accepted more students, I was instead receiving one-on-seven help. Meanwhile, I was still failing every class except for math. Three weeks later, I told myself, “I can prove the fraudulent, incompetent owner wrong. I will learn English by myself, and I will catch up in two years.”

The next day, carrying a yellow notepad with four distinctly-labeled columns - vocabulary, definition, translation, sentence, I started executing my plan right away. I quickly jotted down new vocabulary, at a pace of 30 words per class. When I got home, I opened up and and learned every word’s definition and translation. Then I put the words in context by creating coherent sentences. The following morning, I got to school half an hour early trying to converse with classmates on first-grade topics. After school, I practiced dialogues with teachers without realizing they had lessons to plan.

Despite the awkwardness, mockery, and occasional all-nighters, I was making tremendous progress. In 3 months, my ESL teacher promoted me to the mainstream English class. In 6 months, my writing was evaluated as beyond my grade level. In 12 months, I received Student of the Month award for working diligently to improve English and earning the highest grade in my mainstream English class. In 24 months, I could communicate with anyone without problems. I was no longer the kid who “didn’t speak your language” or “acted differently”. I achieved the goal of catching up my English in two years, half of the time the owner claimed, all without going to her tutoring center.

This journey has fundamentally shaped the way I approach challenges. Without the resourcefulness I acquired through learning English, I wouldn’t have become proficient in four programming languages in two years. Without the independent learning I constantly practiced, I wouldn’t have successfully created and operated eight web applications by myself. Without the confidence I built up trying to become a better speaker, I wouldn’t be brave enough to speak on interviews with KCBS, Inc. Magazine, and The Mercury News about young entrepreneurship.

Steve Jobs spoke accurately in his 2005 Stanford Commencement Speech, “You can't connect the dots looking forward; you can only connect them looking backwards.” When I first set foot in the U.S. in 2008, I had no idea what I would become five years later. Looking back now, it’s amazing to see how my dots connect.
