A company called Qubit pocketed a $26 million raise today (in singles, we presume), because fixing poorly designed e-commerce sites has proved to be good business.

Known to itself as “the e-commerce technology company,” Qubit tells us it helps e-commerce business improve their sites by identifying shoppers’ “patterns of behavior.” These patterns may, for example, reveal that a business’ “buy now” button is too small.

Qubit isn’t solely in the business of enlarging buttons, of course. That was only an example.

Accel Ventures led the round, but Balderton Capital’s and Salesforce’s venture arm also threw in some cash. In a press release, Accel touts that Qubit was founded by “four ex-Googlers” and “has achieved 260 percent year on year growth in sales in the six months to June 2014.”
