Will run web3 hackathons, create web3 services with clients

Tokyo—December 5, 2022—Hakuhodo Inc., a leading integrated marketing and innovation company headquartered in Tokyo, is pleased to announce the launch of HAKUHODO KEY3 INC., a new venture dedicated to developing web3 services with clients while planning and running web3 hackathons. HAKUHODO KEY3 was established on December 5, 2022, in partnership with Sota Watanabe, CEO of Singapore-based Stake Technologies Pte Ltd, developer of the Astar Network, a public blockchain originating in Japan.

web3 is the next generation of the internet, making use of decentralized technologies such as the blockchain. The Japanese government’s Digital Agency is championing the implementation of web3 as a key element of its strategy for building a digital society. Several preconditions are essential if web3 is to become part of our daily lives. It must offer services in a secure form via a public blockchain accessible to all. It must be easy to use. And it must deliver a user experience that makes sei-katsu-sha* eager to try it.

Hakuhodo has already been working with Sota Watanabe on helping clients enter the web3 market by leveraging the Astar Network. Now the two have teamed up to establish HAKUHOD KEY3, which is in the business of planning and running web3 hackathons. A hackathon is an event where IT engineers and designers form teams and, while pooling their ideas, compete to develop applications or services in a specific area within a set timeframe. By so doing they support web3 service developers. Blockchain-sponsored hackathons are increasingly becoming the primary means of developing services on web3. Yet few hackathons originate in Japan. HAKUHODO KEY3 will, while drawing on Hakuhodo’s twin strengths of sei-katsu-sha insight and creativity, organize hackathons all over the world in partnership with clients ready to sponsor them. These will be held on topics designed to enhance the client’s advantages and assets, cultivate sei-katsu-sha demand, and boost developers’ motivation. In the process, the new venture will build a network of connections with engineers worldwide and develop services that will be key to the web3 society.

HAKUHODO KEY3 aims to launch world-class web3 services from Japan. It will thus, alongside client firms, help build a society where more sei-katsu-sha can participate in web3.
