TweetTV, the social TV guide, has recently received $750K in funding from angel investor Joe Kalfa.

TweetTV categorizes and enhances TV-based conversations happening on Twitter, and the company hopes to use the funds to develop mobile aps, hire engineers, update its proprietary algorithms and launch its partner and social rewards programs.

TweetTV updates by the minute to display real-time TV viewership trends with local channel ratings per the user’s TV provider. Users can locate the social buzz surrounding current TV programming on the fly, and enter cloud-based embeddable “tweet rooms,” to curate Twitter-based conversations.

Founder/CEO Bradley Markham says, “I couldn’t be more excited about the future of tweetTV. Not all investors or investments are created equally, and in Mr. Kalfa, we found the perfect seed-stage investor who shares tweetTV’s vision to create a platform for meaningful social TV conversations and TV discovery tools that re-invent the TV guide.” Kalfa adds, “I strongly believe in tweetTV’s vision for becoming the de-facto way for socially active TV viewers users to engage with each other while watching TV.”

TweetTV was founded by Markham in 2009, sans outside funding, and was released as a beta version to the public last November.
