Squarespace: an AdWords-to-Super Bowl success story

What a difference 10 years makes. In 2004, Anthony Casalena launched his website publishing startup Squarespacewith $100 in advertisements on Google(NASDAQ: GOOG). This year he's plowing $4 million into a 30-second Super Bowl spot.

It's a coming out party of sorts for Casalena's company, which has been under the radar despite making money from year one. These days the company, which Casalena started in his University of Maryland dorm room, has 259 employees and offices in New York City's trendy SoHo neighborhood.
