Kraig Biocraft Laboratories Inc (KBLB)

The "Goo" companies need a lot of upfront capitol in order to build a decent enough lab to produce the fibers, but after that initial cost, it seems pretty cheap to operate, especially in Bolt Thread's case. It is very expensive to scale larger, though, which is why they need the tens of millions of dollars. There are many advantages to the protein method, but the initial cost makes it a very difficult market to get into.

Spiber seems to be concentrating solely on the Japanese domestic market for the time being and Bolt Threads is looking almost exclusively at mundane textiles from companies that are really big in environmentalism and sustainability. If KBLB focuses initially on Technical Textiles (which it seems like they are), then there shouldn't be very much competition between the big three spider silk makers for a while.
