Theme: [DMM, which does everything] x [Web3] products

DMM offers more than 60 services including video distribution, FX, English conversation, games, solar power generation, 3D printing, etc. We are looking for ideas and products for new businesses and measures that take advantage of the characteristics of Web3 and cross them with existing DMM businesses.

Examples of products

Service ideas that will bring DMM's services to a wide range of Web3 users

Ideas that enable users of existing DMM services to experience the appeal of Web3 technology

Evaluation Points

Is the idea an idea that makes use of DMM's existing assets (business, members, systems, etc.)?

Is the idea technically feasible?

Points to note

The implementation of the demo is only acceptable if it demonstrates the concept of the idea.

Please refrain from capturing screenshots of the actual service, crawling to the service, etc., and do not use the actual content provided on DMM.

The best ideas may be connected to a person in charge within the DMM Group through a person in charge of the Web3 Division, and may be considered for commercialization. Please refrain from negotiating directly with or inquiring to the person in charge within the group in any other way.

We transferred our adult business to Digital Commerce in 2018. Digital Commerce is not a group company and cannot consider any proposed synergies with the adult business.
