A “business model for an innovation funnel” refers to the strategic framework used to manage the different stages of an innovation process within a company, typically involving a funnel-like structure where a large number of initial ideas are gradually narrowed down to the most promising ones through evaluation and filtering, ultimately leading to successful commercialization; key business models within this framework include open innovation, stage-gate process, lean startup, and platform business models which each have their own unique approach to idea generation, evaluation, and development within the funnel stages.
