Think investing is too hard or too time consuming? Betterment might be for you.

Betterment uses really sophisticated computer programs to figure out the best -- and cheapest -- fund mix just for you. It even factors in taxes.

You just need $1 to begin. You answer a few basic questions and then Betterment does all the work by actually investing your money and monitoring it over time. Traditional financial advisors provide a similar service, but they typically charge about 1% a year. Betterment only charges 0.15% to 0.35% (fees vary based on how much money you invest).

Betterment says that its portfolios outperformed comparable advisor-managed portfolios 88% of the time over more than 30,500 periods it tested.

"The way people invest is changing dramatically," says CEO and founder Jon Stein. "I started Betterment to re-invent the investing industry so that it would work as we want it to."

Founded in 2008, Betterment already has 168,000 customers who entrust the company with a total of $4.8 billion in assets. And yes, the company uses computers a lot, but customers can still call or email Betterment seven day a week and get a real human.
