Which parallel model is based on using the Income generated by an existing business model to fund a new digital business model until can fund itself?

The synergism parallel model is a business strategy where an organization operates a new digital business model alongside its traditional one. The defining feature of this model is that the income and resources from the established, existing business model are used to finance the new digital venture. This funding continues until the new model achieves profitability and can sustain itself financially. This approach leverages the stability of the current business to incubate and de-risk the launch of the new one, creating a supportive, synergistic relationship between the two.

A. Cannibalism: This model describes direct competition where the new business model actively takes market share and revenue away from the organization's existing model.
B. Erosion: This refers to a gradual decline of the existing business model as the new model slowly attracts its customer base or makes it obsolete.
C. Concurrence: In this model, the old and new business models are run simultaneously but are kept separate, with no direct financial or operational relationship between them.
