. Communicate with the Nippon Foundation and DeepStar to understand general needs for proposals requested funding from the NF DeepStar Partnership Program. . Engage with DeepStar core members/operators to understand DeepStar operators’ business and technical needs. 。 Find overlapped areas between the needs of DeepStar operators and the technical capabilities of Japanese companies. . Develop ideas for proposals in such overlapped areas – a Japanese company can also work with another international tech company to jointly deliver a project. 。 Convince at least one technical representative from a DeepStar core member/operator to champion the idea to develop it into an official proposal. 。 Submit the one-pagers/proposals to the Nippon Foundation between Jan 14 and Feb 14, 2023 (or any updated dates Nippon Foundation provides). . Plan to attend the DeepStar Technology Symposium on May 5, 2023, in Houston. . Get ready to start the projects by June 2023 (if the proposals are approved). Proactively get engaged with DeepStar core companies during the project work. .
