Maiora Capital

Founders Jason Block, Patrick Wheen, and Marzio Keiling lead the firm. Block founded Maiora Asset Management; Keiling is the founding partner of Maiora Renewables. The partnership structure centralizes both venture and infrastructure allocation decisions within this group, with Keiling overseeing energy assets directly.

The firm's dual venture-and-infrastructure model provides proprietary origination. Operating solar farms in Japan and Taiwan gives Maiora on-the-ground relationships with developers, regulators, and offtakers — channels that inform both its infrastructure pipeline and its venture-stage energy-tech investments.

Maiora Capital is structured as an asset manager, not a family office. It operates Maiora Asset Management and Maiora Renewable Energy as parallel vehicles, sponsors a listed infrastructure corporation with institutional partners, and has accepted co-investment from Farallon LLC.

Maiora co-sponsors Enex Infrastructure Investment Corporation alongside ITOCHU Enex and Sumitomo Mitsui Trust Bank. This listed vehicle holds Japanese infrastructure assets, and the sponsorship reflects Maiora's institutional standing in Japan's renewable-energy market.

Yes. Farallon LLC has partnered with Maiora to provide late-stage capital for solar portfolios in Japan and Taiwan. The firm's AIMA membership further signals that it engages with institutional allocators and follows industry-standard operational practices.

The venture arm covers seed, startup, early-stage, and growth/expansion rounds. There is no public evidence that Maiora makes fund commitments as a limited partner; its disclosed activity suggests a preference for direct investments and co-sponsorship structures.

The initial capital base is not publicly disclosed. The partnership structure and co-investment relationships indicate the firm operates pooled capital, likely from the founders and external institutional partners, rather than a single-family wealth origin.
