## About

JMX Capital was established in 2019 as a registered investment advisor headquartered in Boston. The firm operates as a wholly owned subsidiary of TPJMS, a relationship that defines its institutional backing and client sourcing. Early disclosed clients include college endowments, positioning the firm from inception as a manager for perpetual-capital institutions rather than retail or high-net-worth channels. The firm deploys capital through customized separately managed accounts, structuring individual portfolios rather than commingled vehicles. Public records indicate a mandate spanning public equities and fixed income, with manager selection and direct security-level discretion both in scope for endowment relationships. The firm's disclosures reference a focus on long-only strategies with an emphasis on total return, consistent with the spending-policy needs of the endowments it serves. No venture, private equity, or direct real-asset activity is documented in the firm's regulatory filings. JMX's ADV filings list a lean team operating from a single location in Boston. The firm's ownership structure—100% held by TPJMS—makes its governance distinct from founder-led RIAs, with fiduciary authority flowing through the parent entity's control framework. Adjacent philanthropic or operating vehicles linked to either JMX or TPJMS have not been publicly identified. No new fund launches, office expansions, or principal-level hires have been reported in the last 24 months. JMX's structural differentiator lies in its parent-subsidiary architecture: a dedicated RIA formed to serve the investment needs of institutions already connected to TPJMS, rather than a firm built through organic AUM aggregation. This captive-client posture reduces marketing dependence but concentrates business risk within the parent's relationship network. The succession and governance path, absent public detail on named principals, runs through the parent entity's own continuity planning.

## Questions

### Who owns JMX Capital?

JMX is a wholly owned subsidiary of TPJMS, as disclosed in the firm's SEC registration. The parent entity's principals exercise control over the RIA's governance and investment policy. No external minority investors or employee equity participation has been identified in public filings.

### What types of clients does JMX serve?

The firm's early and publicly acknowledged clients include college endowments. This institutional focus shapes JMX's mandate toward total-return strategies aligned with perpetual spending policies. The firm's ADV filings do not indicate a retail, high-net-worth, or family-office client base.

### What asset classes does JMX cover?

Public equities and fixed income form the core of JMX's documented mandate. The firm's regulatory filings do not reference allocations to private equity, venture capital, real estate, or hedge funds. The strategy is long-only with an emphasis on total return suitable for endowment spending needs.

### Who runs investment decisions at JMX?

No named principals—such as a CEO, CIO, or portfolio manager—have been publicly identified for JMX. The firm's SEC filings list control persons through the parent entity TPJMS, but individual investment-committee members or key decision-makers are not disclosed in available public records.

### Does JMX participate in co-investments or pooled vehicles alongside external managers?

There is no public evidence of JMX engaging in co-investments, fund-of-fund commitments, or club deals. The firm's separately managed account model and endowment-focused mandate suggest a preference for direct, transparent portfolio construction rather than intermediated or collective investment structures.
