We invest in
to drive growth




In recent years in Japan, there have been a number of cases where start-ups have not been supported by patient shareholders who properly ascribe value to those businesses which, despite near-term operating losses, are aggressively investing for future growth with upfront investments. As a result, in many of these cases post-IPO, this has resulted in volatile and stagnant share prices, thereby limiting these companies' ability to strategically invest for further growth. Furthermore, the number of late stage*institutional investors who can provide patient capital at scale are still very limited, which forces a number of start-ups to go public before they achieve sustainable profits.

*Late stage refers to a state in which the business model has been established with robust and proven unit economics with a structurally profitable financial model.

Our Mission

Minerva Growth Partners (hereinafter referred to as "MGP") provides start-ups with the option to raise sizable capital not only through IPOs, but also through private capital raising which allows them to aggressively invest capital and management resources for the strategic growth of their businesses. By doing so, we believe that Japanese start-ups will continue to invest boldly based on a long-term strategic vision, rather than simply focusing on short-term profits and losses, and that this will create greater competitiveness and vitality across these industries in Japan. By providing growth capital backed mainly by our local and global institutional investors, MGP will support the creation of the next generation category leaders from Japan whom we believe may ultimately compete globally.



Minerva Growth Partners is established by Kei Nagasawa, former Mercari CFO, and Kensuke Murashima, former Head of Japan for Global Internet Banking/Global Software Banking Group at Morgan Stanley, together with Pleiad Investment Advisors*.

Pleiad Investment Advisors is an independent asset management company established in Hong Kong in 2014 and is an approved asset management company by the Securities Futures and Exchange Commission (SFC) of Hong Kong. It invests in public companies in the Asia Pacific region (mainly Japan, China, and South Korea) through in-depth and extensive research, and specializes in a long-term, fundamental investment approach characterized by a relatively small number of concentrated holdings. As of the end of December 2023, it manages approximately 240 billion JPY (1.7 billion USD) and has a track record of investing in a variety of newly-listed growth stocks among Japanese start-ups. http://pleiadadvisors.com

Growth-Stage Investing

Minerva Growth Partners ("MGP") plans to invest from 1 to 3 billion yen per company, primarily targeting growth stage private companies that have established product-market fit (PMF), revenue models, and an attractive unit economics to grow towards 10 billion yen scale in sales. In addition, we will also make private equity investments in growth-stage public companies and their business units and subsidiaries. Our focus areas include consumer internet and B2B software and services including healthcare tech and fintech.

Buyouts / PIPEs / Carve-outs

As a private equity fund focused on growth companies in the technology sector, MGP is able to offer a variety of strategic solutions, not only limited to investments in unlisted companies, but also buyouts, private investments in public equities (PIPEs), and carve-outs of specific business units or subsidiaries.  In particular, we support companies who have concerns regarding their valuation in the capital markets, liquidity and stock price which make it difficult to raise capital, preventing them from pursuing proactive measures.  MGP addresses these issues through providing strategic solutions through our private equity investments.
