Online video discovery engine Taboola has secured $4.5 million in a second round of funding. Previous investor Evergreen Ventures led the round, which also included funds from a new group of Israeli and American investors. The Tel Aviv-based company rolled out a new product called ViDiscovery (NSDQ: DISAB), which lets publishers incorporate its search and recommendation tools on their site. It also has a service called DiscoverAd, which inserts both text and video ads within the recommendation stream. Taboola’s publisher-facing products help it compete in a consumer-centric video discovery market that includes fellow startups like Vadver and MeFeedia, and to a lesser extent, established providers like Pixsy. Taboola has raised a total of $6 million since its launch in 2007. Release.
