Another VC firm of interest to green job seekers: VantagePoint Capital Partners.

They've invested in 31 cleantech companies, and we have 16 of the 31 setup on The Green Job Bank, with all their jobs. As of today, they had a combined total of 134 green jobs.

Tesla Motors, the electric car company, is by far the one hiring the most, with over 70 open positions. Solazyme comes in second with a solid 29 jobs. Most of the others have a just handful of jobs openings.

There's a bit of overlap and co-investing with other venture capital firms, but not much. Here are the VantagePoint portfolio companies that also took money from others:

• Mascoma's investors also include Kleiner-Perkins and Khosla Ventures.
• Miasole's investors also include Kleiner-Perkins and Birchmere Ventures.
• Serious Energy's investors also include Foundation Capital and NEA.
• Solazyme's investors also include Braemar Energy Ventures.

In my opinion, it's a good sign when a startup takes money from several well-known and large VC's. First, they were able to convince several of them to invest in their idea, which is no small task; and second, they got more money.

On the other hand, it's quite common for startups to raise money from more than one VC, for several reasons. First, the initial round of investment (called "Series A") is often smaller, and attracts different VC's than the second round (or "Series B"), which is most of the time much larger. Second, some VC's don't like to invest alone, and want to spread the risk by asking others to participate in the round.
