Feld was born in Arkansas and grew up in Dallas, Texas. His father is a doctor and his mother an artist. As a child he loved school:
As a kid, I learned to work hard, be responsible for my own actions, and be curious about everything.
While in high school he starts an SAT tutoring business and makes $30/hour.
I made the same amount of money in four hours that my friends made working 40 hours a week, had control over my time, and could work on whatever I wanted.
His senior year in high school and first year in college he worked for a startup software company called Petcom as the first employee (they grew to 20 employees).
I got paid $10 / hour + 5% of gross sales of the software products that I wrote. As checks for $5,000 – $10,000 came to me each month when I was in college, I decided I liked that a lot better than working for a salary somewhere.”
