I crawled through the German web and – besides noticing and wondering how many new mom&dad, sport and pet communities we have – collected a decent list of mobile startups.

If you know a company that is missing please add it in the comments. I will keep an eye on any new startups and follow up on this in the future.

Videos are uploaded and downloaded with the video call functionality of the phone. This makes it incredibly easy to access the service even for folks that are not so technically savvy. The only prerequisites are that your mobile network operator (MNO) runs a video-call-enabled 3G network and that your phone supports those video calls. All German operators provide access to ViiF with rates between 0,39€ and 0,58€ per minute for recording and watching content. O2 currently provides free access, which makes the service especially interesting for O2 users.

After calling ViiF’s short code number from your mobile phone you are in a video call and can choose between recording a new and watching existing videos. Recorded videos can be saved in different folders to share publicly or only with friends.

Friends can be notified by SMS that a video has been recorded. Furthermore, it is possible to add ViiF to your blog with the ViiF Player and vblog your recordings to the blogosphere.

Besides streaming to and watching videos from your friends ViiF provides even more entertainment. They have contracts with MTV, ProSiebenSat.1-Group (large German TV stations) to push news, music, movie trailers and other additional content on your mobile.

Although ViiF is only available in Germany so far it is one of the first German websites that has a Facebook application. Facebook has not entered the German marked with a localized version yet but this is expected to happen in the next couple of weeks. Until today the Facebook-clone StudiVZ is the most active social network for college students in Germany. Facebook’s platform is way superior to the poorly copied StudiVZ website and I am expecting that most German students will turn their back to StudiVZ as soon as the language barrier drops. This makes ViiF’s Facebook Application a great move for the future.

ViiF is based in Berlin and has raised an undisclosed amount of venture capital from Neuhaus Partners, VC Fonds Berlin and various business angels. They have even been nominated for (but didn’t win) the Mobile Monday Peer Award 2008.

ViiF is a great service but to make this a true success ViiF has to master the difficult task to get the mobile network operators to lower their prices or to provide the service for free as it happened with O2. If this is not possible another way has to be found on the long run to access ViiF. Unlimited mobile data plans are becoming cheaper in Germany and nobody will pay those prices per minute if other vblogging services can be accessed over the Mobile Web free of additional charge.

The venture has been founded in 2005 by Felix Petersen and Stefan Kellner in Berlin, Germany. By 2006 Plazes had secured seed financing from business angels such as Esther Dyson, Marc Andreessen and Martin Varsavsky. In 2007 Plazes raised €2.7 Million from Doughty Hanson Technology Ventures in another round of funding.

Plazes originally started to map a user’s location based on the MAC address of the wireless network that was being used. New routers were discovered by users and tagged with geo-coordinates. After having downloaded a “Plazer” your notebook was capable of detecting your current location by investigating the network you were using.

Nowadays there are plenty of different locations, which are not tied to wireless networks anymore, in the system. The tracking no longer relies on wireless networks. A user can submit his location by SMS, the website or an updated version of the “Plazer”. The new activity concept adds a Twittery Twist to Plazes so that I can describe what I am doing when broadcasting my whereabouts to the world. The latest version is also preserving a user’s update history and allows planning meetings in the future. Recently a new API has been released to enable developers to build their own applications and to extend the reach of the Plazes network.

Even though Plazes is based in Germany its majority of users is from the United States. Many similar location-aware services like Loopt, Helio or Dodgeball (still alive?) exist and similarities between Plazes and websites like Twitter and Jaiku are evident.

To gain more users the challenge for Plazes will be to distinguish itself from comparable services. Opening the system with a new API is definitely a step in the right direction. It will be interesting to watch the fight between the mobile social networks and how Plazes evolves in the future. I will keep an eye on them and inform you about any interesting updates.

Are you using Plazes? What do you think should Plazes do?

Damn sure there are! During my research I was not bombarded with dozens of mobile startups, but I found a hand full of interesting and innovative companies I want to further elaborate on in future posts. Partly those companies are even targeting an international market and are not only focused on Germany. Stay tuned for the next posts!
