It's hard to stay focused in the digital world, but Signal founders Jeff Judge and Chris Watland have turned their SMS-marketing startup into a web success story by emphasizing the fundamentals. The duo got in on the ground floor of the exploding text-marketing industry, building an easy-to-use platform for firms managing SMS campaigns. Today Signal has evolved into a cross-channel marketing platform for managing text campaigns, e-mail marketing,social mediaand even coupons and sweepstakes from a single cloud-based account.

And they did it without a dime from outside investors.
