I called a friend of mine who knows this space very well. I asked him who Stern Brothers was and if it was a good idea if Blue Sphere hired them. I had never heard the name. He told me that it was pretty much the other way around. It is more like Stern Brother chose Blue Sphere. He said that they are really picky and don't just take on any client. Said they are top firm for project financing and have been around for a really long time.
It sounded really encouraging to me. Fingers crossed.
