Sustainable business is a very poor choice of words for a VC to use in this context. Your investment doctrine might require companies to pursue 10X growth or die trying, but... that means your investment model is not about sustainability (of the businesses you invest in). The businesses could be perfectly sustainable. A startup is not necessarily guided by sustainability. Amazon lost money for decades. FB never bothered to make money until their IPO. They were not pursuing sustainability at those points. They were betting on growth.
