One third of the economy goes through 'QuickBooks' in terms of businesses invoicing other businesses. Each invoice contains a connection between vendors, suppliers, and customers, and also the price of that connection. Representing the payment graph is huge opportunity and something no other company can do.
I wanted a personal-finance tool for people who didn't want to be accountants: something you could set up in ten minutes and spend less than five minutes a week on. Mint is now that tool.
I actually don't invest in anything that is social, mobile, deals or ad networks simply because those are areas where there are so many players and so many other smart people in the space, I feel like I don't have a competitive advantage. So I tend to go after things that are e-commerce, like healthcare.
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.
In the first three years of Mint, from when it was founded to when it was sold, I can honestly say that in a sustainable way, I couldn't have worked any harder on it.
Most people don't know what they spend in every single area, but they know they have a problem in particular areas.
I consider myself an inventor first and an entrepreneur second. In real life, my hero is Thomas Edison. He was a great inventor, but also an outstanding entrepreneur who was able to sell his inventions to the masses. He didn't just develop the light bulb; he invented the entire electric grid and power distribution system.
I have always thought of myself as an inventor first and foremost. An engineer. An entrepreneur. In that order. I never thought of myself as an employee. But my first jobs as an adult were as an employee: at IBM, and then at my first start-up.
When I was 8 or 9, I started using bulletin board systems, which was the precursor to the Internet, where you'd dial into... a shared system and shared computers. I've had an email address since the late '80s, when I was 8 or 9 years old, and then I got on the Internet in '93 when it was first starting out.
Mint's business model became, 'We'll go for free, and then we'll find these savings opportunities for you.' You know, better interest rate on your credit cards, when should you consolidate your student loans, when does it mathematically make sense to refinance your mortgage, and Mint figures all that stuff out for you.
Kevin Systrom of Instagram used to work for us as a consultant in the early days of Mint. I knew him a long time ago. Maybe I could have gotten in there. But with photo sharing, I don't know if there's an obvious business model. I don't think there's a competitive, sustainable advantage.
I think sports and bodybuilding were the only things that saved me from getting beat up. People are not pleased, for whatever reason, when you can answer all the questions in class. If not for the respect I got from track, cross-country, wrestling and bodybuilding, it would have been a disaster.
