Seibert was one of Tumblr's first bloggers, an angel investor in the company, and served on its board before its acquisition. Seibert was the original angel investor in Sawhorse Media, the company that created the Shorty Awards and MuckRack, a public relations management platform that enables organizations to connect with journalists to generate media coverage. Seibert and his Frederator Networks partnered with John Borthwick and Betaworks; Jonathan Miller, Jason Ostheimer, Shari Redstone; and entrepreneur Yoel Flohr to form Thirty Labs in 2014, a startup studio based in New York City to develop and invest in video based technology businesses Seibert is CEO and Flohr, COO.
