Innovid, a video advertising startup, has raised $4 million in funding from T-Venture, the venture capital company of Deutsche Telekom. This brings the startup's total funding to $7.1 million. Innovid develops a pre-roll advertising product, called iRoll, that allows advertisers to insert 3D objects into video ads. The ads are intended to look as realistic as possible so that they blend in with the real physical environment recorded by the video.
