Held annually, ENECHANGE Insight Ventures (previously Japan Energy Challenge) is an opportunity for innovative companies operating in the energy sector, to meet and connect with large Japanese corporates, our subscribers. The goal is to build relationships that result in collaborations, sales, investment, and other forms of support for helping grow the invited companies in Japan.

This competition is unique in that all invited companies will have at least one sponsor interested in meeting them specifically. The EIV team works with the invited companies in the months leading up to the event to fully understand their business and products.

The event itself will represent the culmination of months of research and back and forth communication, making the actual meetings very meaningful to exploring future relationships.

Find out more about the program and how to apply to ENECHANGE Insight Ventures here.

Stage I - Scouting

By looking at current investment trends within the Global energy market we identify the most promising sectors and perform detailed research on the best companies therein.

Stage II - EIV Participation

The companies we select are carefully vetted by an experienced team of energy professionals, until a suitable list of participants to EIV is agreed upon with the program’s subscribers.

Stage III - Investment

Of these finalists, only a select few will be considered for the fund, based on product fit with the Japanese market and success of EIV participation we throw our weight in behind top-tier projects.
