I want to build products that live for as long as they are useful, irregardless of the fate of the company that starts them.<p>Too many products i've loved are dying. Wunderlist, Google Hangouts, Parse, etc.<p>I want to know what you've done to make your product last for a long time. Is open source the answer? Allowing users to self-host? Structuring your company as a non-profit?<p>How can people build products that live forever?
