These days, you need to be capital-efficient

Back in the 90's, VCs would put millions of dollars in a high-tech start-up, and patiently wait several years for the start-up to build its hardware product (software is a different story).  If the product was successful, everyone won, and many did.  It's not that way anymore for most investments.  Unless you truly have a blockbuster hardware product, these days your start-up needs to be capital-efficient:  less money has to go farther, and the point in time when your start-up either gets springboarded to the next level or gets its plug pulled is shorter.  Keep that in mind when developing your funding strategy and product roll-out strategy.
