On-demand home-services provider Serviz received a second round of funding of $12.5 million led by a Silicon Valley venture capital firm. The Sherman Oaks company has now received a total of $20 million in the five months since its launch in Los Angeles and Orange counties. Serviz provides an online platform to schedule and pay for handymen, plumbing and electrical work, carpet cleaning and appliance repair. The company works with licensed professionals who do the work. It was co-founded by Zorik Gordon, founder and former chief executive of ReachLocal Inc., a Woodland Hills online marketing company. PointGuard Ventures, in Menlo Park, led the Series B investment round that included prior investors Gordon, Andy Sheehan, and Stibel Investments. The first round was led by Groupon Inc., the deal-of-the-day website, in Chicago. Gordon said the additional money will allow Serviz to expand the home-repair categories now offered from five to 20 and move into 20 additional geographic markets. “This latest round is a strong validation of our momentum to date and the size of the opportunity ahead of us,” he said, in a prepared statement.
