Intuit Inc.
A financial technology company whose tools touch everyday money: QuickBooks and Mailchimp for businesses, TurboTax for tax filing, and Credit Karma for personal finance. It began in 1983 when Scott Cook and programmer Tom Proulx built Quicken to help Cook's wife balance the family checkbook. The name "Intuit" comes from "intuition"—software meant to be so simple it needed no instruction manual.
