Zaishi Capital

Zaishi Capital operates under the Restone Capital brand. The firm's website at restonecapital.com presents Restone as the outward-facing identity, using a Chinese name (再石资本) that translates back to Zaishi. The single legal entity focuses its entire investment activity through this climate-tech mandate.

Zaishi Capital invests from seed and startup through expansion and late-stage growth, per its stated strategy. This allows the firm to back climate-hardware companies from laboratory-stage prototyping up to commercial-scale factory builds, maintaining exposure across the development lifecycle.

The firm targets three core verticals: energy transition, advanced transportation, and industrial upgrading. Within these, sub-themes likely include electrification, battery technology, sustainable fuels, next-generation mobility platforms, and the decarbonization of heavy manufacturing processes.

Available disclosures describe direct venture investing across stages without mentioning fund-of-fund commitments. The firm's strategy appears centered on building a portfolio of direct equity positions in climate-tech companies, though the absence of detailed reporting leaves its full approach unconfirmed.

Altss classifies Zaishi Capital as an institutional asset manager with a private equity strategy. There is no public evidence of a single-family wealth origin or a multi-family office structure. The firm operates as a dedicated venture capital platform rather than as a family's private investment office.
