Introducing the Fortune 500+ Web app by Daniel Roth @FortuneMagazine May 5, 2011, 9:38 AM EST E-mail Tweet Facebook Google Plus Linkedin Share icons The Fortune 500 has always been more than a list. Salespeople plumb it. Executives wield it as a yardstick to measure market share (99% of the Fortune 100 use our software). Entrepreneurs dream of appearing on it. For more than 50 years, it’s been the preeminent method for measuring business. Now, we’re turning it into a vital tool for doing business. Starting today, you can download the Fortune 500+ Web app and quickly find out which companies you need to know and — thanks to the power of LinkedIn — who you know at each one. Users can: Target the 1,000 biggest companies in the U.S.; Locate your connections using LinkedIn; Find the right companies to meet with or sell to; Track breaking news and Twitter traffic; Monitor stock performance and financials; Build, map and share lists of prospects. Using Google News and Fortune’s financial reporting, the app’s content is always up to the minute. You can expect to see frequent new features, new platforms, and new partners as we continue to expand the app’s functionality. And finally, a little about what’s under the hood. We built the 500+ as an HTML5-based Web app, a new class of apps that harnesses the power of modern browsers to replicate the performance of hard-drive based software. You’ll notice how quickly all of the information loads, searches and displays — and how it works even when not connected to the Internet. Below is a brief video and some screen shots showing you how the app works and why we think you’ll find it indispensable.
