Latest Silicon Valley start-ups: Tagged, Arcadian, CarHarbor

Tagged — This new San Francisco developer of “teen-focused businesses,” has raised $7 million in a second round of funding, according to a regulatory filing noted by PE Week. We just looked at the Tagged site, and are a tad surprised it is soaking up that much money. Ok, so it booted us out, because we are not teenagers, and so rejected our registration. But look at the initial model, and it looks like a scheme to appeal to youth vanity and have as many of them sign themselves up as possible — including their friends. So it’s hard to know what it will do next. Backers include Mayfield Fund, while outside directors include Reid Hoffman and Peter Thiel.

The more friends in your Tag Team, the more points you’ll score, with a bonus +100 points if you’re the first person to invite a new member! …Do you think you have what it takes to be a star? Once you invite enough friends, build a cool enough Tag Team and reach a score of 77, you qualify to audition for The Reality Show!

Arcadian — Silicon Valley serial entrepreneur Davidi Gilo is raising a whopping $85 million in…

a first round of funding for his new Woodside-based networking communications startup, Arcadian Networks, according to BusinessWeek’s DealFlow blog. Most people don’t know who Gilo is. But in the Mercury News’ analysis of campaign fund-giving in 1999-2000, his name was No. 1 on the list of “soft money” donors — by a wide margin, with $1.2 million to the Democratic Party. Mother Jones has a related piece. Gilo is a 45-year-old Israeli-American who seldom grants interviews, and most recently was chairman of a wireless broadband company called Vyyo. He is pretty well known in Israel, though, where he launched a hostile takeover of Israel’s largest tech firm in 1996, Scitex, and then later sold his company DSP Communications to Intel for $1.6 billion.

Parking your car in a city? — CarHarbor is a great idea. Starting in San Francisco, it wants to help you find a parking space in a city by providing an online platform for people who know they have a parking spot, but who don’t need while they’re away, to enter it into the network along with a price. People looking for a spot can call a number with their mobile phones to find best location, and pay from their account. (Arrington at TechCrunch has scoop). Note that it hasn’t launched yet. Advisors include Craig Newmark (of Craigslist) and Scott Rafer (of Feedster).
