"We found in user tests that many employees don't have email, and even run on prepaid phones." Anyone reading along should remember this point. It's worth remembering because I've seen it over and over from when I started in the job market all the way today with even Fortune 100 companies. Those I know that did something about it usually involves signing in with username & password over Internet. Many of these companies have workers that don't want to deal with their crappy intranets or just have prepaid phones. A service that either totally or as an option appeals to such people has a massive, potential userbase to draw on if they can convince companies to use their software.
