LivePerson has closed a $19m second round of financing led by Highland Capital Partners, Goldman Sachs Group and Hambrecht & Quist’s Access Technology Partners LLP. The company has also opened a new office in San Francisco. The market for LivePerson’s web-based customer service and sales support software is growing fast. Customers include Tickets.com, sixdegrees and CBS Sportsmen’s IGoGolf.com. Robert LoCasio, president and CEO, boasts: In 16 weeks we went from having ten clients to over 120… We went from eight people on staff to over 40 people. He attributes the company’s success to its technology, which does not require customers to undertake any hardware or software installation.
