We provide technology that can help create multiple different business model proposals easily and without incurring excessive time and cost. The
server, acting as a business model proposal creation support device, accepts monetization target
feature data, which is
natural language data describing the characteristics of the monetization target—the products and services to be monetized—input by the user. Within the
server, there is a prerequisite data generation unit 223 that deepens the prerequisites for the existence of the monetization target features in
multiple stages, and a rationale data generation unit 224 that estimates the market for the monetization target and deepens the rationale for the existence of the market in
multiple stages. Combining the prerequisites and rationale estimated by both units, the business model proposal data generation unit 228 generates multiple or single business model proposals based on a specified number.
