Private Equity HUB today uncovered that Mesmo.TV, a social video bookmarking service and provider of a very popular Facebook application, has secured over half of a $900,000 round of Series A financing.

Mesmo.TV’s Davin Miyoshi informed us that Aydin Senkut’s Felicis Ventures, Mike Maples’ Maples Investments, Naval Ravikant’s The Hit Forge, and Georges Harik participated in the round.

We wrote about the launch of Mesmo.TV’s social video bookmarking tool this past July. The tool, which is found on the company’s website, allows users to rate and tag the videos that they enjoy. Mesmo.TV can then recommend videos to you and introduce you to other viewers with similar viewing habits.

This tool, however, has not turned out to be the most successful part of Mesmo.TV’s business. The company’s TV Show Trivia Facebook application, which launched in August, has garnered over 1.3 million users and over 125,000 daily unique visitors. This puts the application amongst the top 45 applications on Facebook, and made Mesmo.TV the largest TV show community on that social network.

Mesmo.TV plans to continue focusing on its social network efforts and looks forward to expanding to other networks, such as MySpace, who might open up in the near future. The company is also talking with TV networks to bring online videos to its users.
