Frequently asked questions
Who runs investment decisions at JS Capital Power?
Peter Jantzen, the founder, serves as Partner and Executive Director and is the named decision-maker. The firm previously listed Romeo Spinelli as a Partner and Strategist before his March 2019 departure to Shell. No investment committee or additional principals have been publicly identified.
What does JS Capital Power actually invest in?
The firm maintains oil and gas exposure alongside deep seabed mineral assets. Its membership in the World Ocean Council and participation in International Seabed Authority workshops confirm an active interest in polymetallic nodule extraction and related subsea infrastructure, though specific portfolio companies or project names are not disclosed.
Is JS Capital Power a single family office or an asset manager?
Altss classifies JS Capital Power as an asset manager, not a single family office. The firm does not publicly disclose a family wealth origin, and its structure — buyout and growth strategies executed from a Swiss corporate base — aligns with a generalist investment firm model.
How does JS Capital Power source deep-sea mineral deals?
The firm sources through direct regulatory engagement. Its participation in International Seabed Authority financial modeling workshops and its first-mover membership in the World Ocean Council place it alongside engineering consortia, national contractors, and shipping operators, creating an origination channel distinct from traditional GP-led fundraising.
Did a partner leave to join Shell, and what does that indicate?
Yes, Romeo Spinelli, formerly a Partner and Strategist at JS Capital Power, joined Shell in March 2019. The move suggests the firm cultivates expertise valued by major energy corporations and may function as a talent bridge between frontier-resource investing and the operational side of extractive industries.
