K2/D&S Management Co
K2/D&S Management Co. was founded by David Sussman, who built the firm as a multi-strategy investment platform based in Westport, Connecticut — a town synonymous with the hedge-fund diaspora that grew out of nearby Greenwich and Stamford. The firm's architecture reflects that geography: it runs a flexible mandate spanning public-market hedge-fund allocations, direct private-equity stakes, venture-capital exposure, and real-asset investments, a combination more commonly found in larger institutional platforms than in smaller, founder-led shops. The investment strategy blends manager selection with direct deployment. On the hedge-fund side, K2/D&S allocates to external managers across long/short equity, event-driven, and relative-value strategies. In private markets, the firm participates in both fund commitments and direct co-investments, with historical exposure to technology, healthcare, and financial services. The real-estate sleeve includes commercial and residential properties, though specific portfolio holdings are not publicly disclosed. Geographic focus centers on the United States, consistent with Sussman's concentration in the Northeast corridor's alternative-asset ecosystem. As a lean operation without a large public-facing team, K2/D&S likely operates with a small group of investment professionals and outsourced service providers, a common model among Connecticut-based family-office-style firms. The firm has not publicly announced new fund closes or major hires in the past 24 months. Its limited public footprint suggests that assets are predominantly managed for a tight group of high-net-worth individuals or family capital, rather than a broad institutional client base. Structurally, K2/D&S occupies a middle ground between a single-family office and a traditional hedge-fund allocator. It offers multi-asset-class exposure under one roof — a structure that mirrors the "outsourced CIO" model but without a formal institutional client roster. The governance architecture appears to rest entirely with Sussman as managing member, which concentrates both investment and operational authority in a single decision-maker, a posture that reduces committee friction but concentrates key-person risk.

Frequently asked questions
Who runs investment decisions at K2/D&S Management Co.?
David Sussman, the founder and managing member, is the central decision-maker for all investment activity. The firm's structure concentrates both portfolio management and operational control under Sussman, consistent with a lean, founder-led investment platform. There is no publicly disclosed investment committee or additional named portfolio managers.
How does K2/D&S allocate across asset classes?
K2/D&S operates across four broad sleeves: hedge-fund allocations to external managers, direct private-equity and venture-capital investments, fund commitments in private markets, and direct real-estate holdings. The hedge-fund exposure spans long/short equity, event-driven, and relative-value strategies. Private-market activity includes both fund-of-funds commitments and direct co-investments, though the firm does not publicly disclose target allocation weightings or sector limits.
Does K2/D&S manage capital for outside investors or just founder capital?
The firm's limited public footprint suggests that assets are managed for a small circle of high-net-worth individuals alongside founder capital. K2/D&S has not registered as a multi-family office or marketed itself to institutional allocators, placing it closer to a hybrid family-office-and-investment-partnership model than a traditional fund manager raising external institutional commitments.
What is K2/D&S's geographic focus?
The firm's investments concentrate in the United States, reflecting David Sussman's base in Westport, Connecticut, and his network within the Northeast's alternative-asset community. There is no public indication of dedicated non-US exposure or overseas offices, though hedge-fund allocations may provide indirect international exposure through external managers.
How large is K2/D&S Management Co.?
The firm does not publicly disclose assets under management or total deployment. Based on its operational profile — a single-office, founder-led shop with minimal public presence — Altss estimates AUM under $250 million. This places K2/D&S in the cohort of lean, multi-strategy operators that run concentrated portfolios for a limited investor base rather than scaling as an institutional platform.
Does K2/D&S publicly report its portfolio holdings or fund performance?
No. K2/D&S maintains a low public profile and does not publish quarterly letters, 13F filings, or performance data. The firm's hedge-fund allocations and private-market positions are not disclosed on its website or in public regulatory filings, consistent with a private investment partnership that does not actively solicit outside capital.
Is K2/D&S related to any other investment firms or family offices?
There is no publicly disclosed affiliation with other named investment firms, family offices, or financial institutions. The firm appears to operate independently under David Sussman's sole leadership, without formal ties to a larger wealth-management platform, multi-family office network, or institutional asset manager.
