Three Fifty Eight Investment Group

The firm does not publicly name its leadership or investment committee. In similarly structured single-family offices, decisions typically rest with the family principal or a designated CIO, though no individual has been identified for Three Fifty Eight through public filings or professional networks. The lack of attribution makes it difficult for external counterparties to assess the approval chain or investment mandate holder.

With no public presence, the firm almost certainly sources opportunities through private intermediary channels — GP relationships, placement agents, private banks, and family-office networks — rather than through inbound pitches or public deal processes. This is standard for family offices that do not court external visibility. No specific sourcing channels have been confirmed.

Nothing in the public record confirms a co-investment appetite. Many private family offices consider co-investment rights a standard feature of their fund commitments, but without disclosed portfolio activity, the firm's posture on direct co-investment remains unknown. Counterparties would need to engage through a known intermediary to assess appetite.

The firm's structure — no public deal announcements, no venture-brand presence — suggests a heavier emphasis on fund commitments than on direct company investments. Single-family offices of this profile often allocate the majority of private-market exposure through blind-pool funds, reserving direct activity for co-investments sourced through those GP relationships.

No sector exclusions or impact screens have been disclosed. In the absence of a published investment policy, counterparties cannot determine whether the firm applies ESG criteria, excludes certain industries, or maintains a wide-open mandate. This is typical for family offices that treat investment policy as private.

The source of capital has not been publicly disclosed. The firm's name — Three Fifty Eight — provides no obvious link to a known operating business, founder, or wealth-creating event. Without a named principal or corporate parent, the wealth origin remains entirely private, which itself is a deliberate structural choice.

There is no public contact pathway. The firm has no website, no LinkedIn page, and no listed office address. Engagement would require an introduction through an intermediary who already has a relationship with the principal or a family-office network, and even then, receptivity is unknowable without direct outreach.
