Evaluating Biotech Startups?

spacey girl asks: "A start-up company i worked for was recently shut down. I've been looking for a new company for quite some time now. i've been offered something at two new startup companies (established in 2000) and I can't find too many references on the web for them. These companies are not exactly computer related but more science related in biotech (pharmaceuticals and such). What kinds of tools are available for evaluating stability and potential of these two companies? I tried looking for the investors but that was a no-go. Also, I'm referring to international companies, not just companies in the US."
