Before Mint.com, I was a long-time user of 'Microsoft Money' and Intuit's 'Quicken.' Both were powerful tools, loaded with features and functionality around taxes, investment, budgeting - too feature-laden, in fact. They took hours to set up, forever to learn, and an hour a week to maintain. ”

The original idea before Mint was a life and goal planning system I called Carpe Viva. The idea was that all of life's goals, from buying a house, getting an MBA, or learning Spanish could be quantified in both time and money. ”

Carefully calculate the potential size of your market to make sure you can grow. Before starting Mint, I knew that there were about 20 million people who had purchased 'Quicken' or 'Microsoft Money' over the years, and 80 million people using online banking in the U.S. alone. ”

I always knew I wanted to be a technologist, so I went to Duke and got a degree in computer science and electrical engineering. Really, I thought my goal in life was to be an inventor, a problem solver, so I thought I needed a Ph.D. to be good at inventions, but it turns out that you don't. ”

I've actually started a number of businesses in my career. So I'm 28 currently, but when I was about 16, I started building Websites, and that's how I put myself through school. I went to Duke with a degree in electrical engineering, computer science, computer engineering, and then to Princeton. ”

After building most of Mint.com's prototype by myself, I talked to anyone and everyone I knew about Mint. It's counter-intuitive, because you might fear someone will steal your idea, but it's the only way to make connections, be sure you're on the right track, and provide a solution for an audience broader than yourself. ”

I know it sounds weird, but the food that I eat, it doesn't make a big difference, and it never has. So, I've saved a ton of money not buying a lot of alcohol, not going out to restaurants too much. So, I think it's part of our culture, and it's part of a social activity more than anything else. ”

If you pay your credit card off every month, get a rewards card. One that gives you airline miles or that will give you 1 percent cash back at least on every purchase. ”

I wanted to build a tool for my generation: people 20 to 40 who don't want to spend time balancing a checkbook or checking multiple financial institutions' websites. Mint does just that, giving comprehensive, quick insights into a user's finances from their computer, mobile phone and/or tablet. ”

I pitch Mint to everyone from investors to engineers, young and old, and I do it pretty much the same way: Here's the problem in the market place, here's how we solve it, and here's how we make money. ”
