One of the biotech industry's great strengths is its unity, a collective purpose that has resulted in remarkable collegiality among companies.

Except for the few competitive situations (which remain remarkably civil in public), everyone roots for the other guy's success. And ideas about financing strategies, recruitment, compensation and other business issues
ricochet through the sector at nearly the same velocity as the pace of the science. This is a group effort.
