The inflection point a corporate startup reaches when it obtains certainty that the new value proposition and business model it designed aligns with its parent company’s business and innovation strategy.
Strategy fit can come in two forms: 1) The corporate startup’s business model fits the company’s search fields for future business opportunities, which have some characteristics of »self-disruption« (also see: innovation thesis). Thus it might get ‘scaled from the edges’. Or, 2) it can be aligned with today’s core business, thus getting management support from the business units, and can leverage existing resources. The latter scenario is more common for most corporate startups.
