Like, why not just publish a version of the famous Joel Test (http://www.joelonsoftware.com/articles/fog0000000043.html), but for management incentives compatible with long-term thinking? Then companies can submit to voluntary review (maybe with a nominal fee) by your Long-Term Business Bureau, and you can issue certifications for ones that meet certain standards. Your go-to-market strategy is the same - you can target mid-sized startups that are looking to differentiate themselves and hoping one or two of them grow into norm-setting behemoths, but you don't have to ask those companies to jeopardize their (and their investors') liquidation strategies.
