FORBES - Dec 21 - Realtime, a social network founded by Vernon Coleman, is a place for live video-based conversations with a group of up to 10 people. Users can log onto Realtime's mobile app, browse through the on-going video chats, which are listed by topic, then jump into whatever one interests them. Realtime is available only in private beta right now, but to expand further, it has raised a $4M seed round led by Alexis Ohanian, the Reddit co-founder who has started a new venture fund, Seven Seven Six. Realtime sits at the intersection of two important - and possibly lucrative - trends in social media. One, the emergence of synchronous group chat, something that has propelled Discord over the past couple of years, as well as Clubhouse's explosive debut last April. The second, an emphasis on video and user-generated video, something fueled by Snapchat and TikTok.
