Individual Mentoring by Japanese Investment Team
How to achieve PMF, build a strong organization, and create a long-term moat? We provide mentoring on a wide range of topics, including value prop design, MVP design and initial user acquisition, GTM strategy discussions, and advice on hiring and fundraising.
Guest CxO Sessions and Expert Network
We offer Ask Me Anything sessions with entrepreneurs and CxOs from our portfolio companies, and networking opportunities to directly access knowledge on products and management. In a small-group Q&A format, we delve into valuable founding stories that are usually not heard, such as business hypotheses and decision-making backgrounds at the time.
Product Expert Mentoring
We provide product-specific support from a product expert with 20 years of PM experience in the US. We offer advice on agendas appropriate for the company's phase, such as persona definition, user story design, UX design, and engineer hiring/organizational design.
Investment at the Start of the Program
Unlike typical accelerator programs, we make an investment at the start of the program. Therefore, from the beginning of the program, we provide coaching and support as an "investee," and continue to provide ongoing support after the program's completion, just like any other investee.
Deep Insights from a Global Investment Team
During the program, we work closely with our global team to provide research and insights on similar cases overseas. At the end of the program, a final presentation to the global team (with interpretation) is held, allowing for intensive discussion on the business.
