Oomavoice-over-internet box that lets users make free land-line calls, brought in $18.3 million in a fourth round of venture financing, reports paidContent. It raised $14 million of this sum back in June.
Based in Palo Alto, Calif., the company says it now sells its box, priced at $249.99 a pop, through 5,000 retailers like BestBuy, Costco and others.
Ooma has now raised $61.0 million to date. The recent round came from Worldview Technology Partners, Founders Fund, TD Fund and WI Harper. Previous backers include Draper Fisher Jurvetson and Draper Richards.
As VentureBeat reported in June, Draper Fisher Jurvetson's stake was converted into common stock, and the firm lost some of its rights, exposing it to further dilution in the future. At that time, the company was valued at $20 million and was looking to raise $20 million total.
