I'm finding the same exact reaction in medtech. Same foreboding myths, same massive opportunities, and same chance to build lean operations. We're grinding along but I'm surprised that tractable obstacles look scary to otherwise savvy investors.
Have you looked into government grants? It's a very different process and set of expectations than a pitch deck, but the capital is non-dilutionary and there is a bunch of stimulus money sloshing around. Obama seems to recognize that the future US economy will be in biotech and greentech.
