Solum Partners

Co-founders Colin Butterfield and Matt Matera serve as Managing Partners and oversee all investment and underwriting decisions. Both spent over a decade on Harvard Management Company's natural resources team, where they directly managed the endowment's global agricultural portfolio. Partner John Duryea rounds out the senior investment team with further HMC experience. The firm operates with a lean central team and relies on established farm-operator relationships rather than a large internal acquisitions staff.

Solum sources deals primarily through its network of farm operators — many of whom the founders worked with during their tenure at Harvard Management Company — rather than through broker-driven auctions. The firm targets operational partnerships where the existing operator continues to manage the property under an incentive-aligned structure. This operator-first pipeline is uncommon among institutional farmland buyers that rely heavily on brokerage networks and formal auction processes.

Solum Partners was formed by the senior members of HMC's natural resources team when Harvard decided to outsource its direct agricultural investments to an external manager. Colin Butterfield, Matt Matera, and John Duryea led HMC's farmland portfolio before spinning the team out in 2020. The firm was initially seeded with capital from Harvard's endowment, and the portfolio they now manage includes assets previously held directly by HMC (per PEI Group, 2021).

Solum targets two broad categories: row crops — corn, soybeans, wheat, and cotton — and permanent crops including almonds, pistachios, wine grapes, apples, and citrus. The firm underwrites each asset based on cost-of-production position and water security rather than commodity-price assumptions. Permanent crops are concentrated in California, Chile, and other Mediterranean-climate regions; row-crop assets span the US Midwest, Mississippi Delta, and select South American geographies.

Solum structures its investments with holding periods exceeding ten years, consistent with the long-horizon approach the founding team practiced at Harvard Management Company. The firm explicitly does not underwrite returns based on short-term commodity-price movements or speculative land-value appreciation. Operational improvements — soil health, irrigation efficiency, and crop-varietal upgrades — compound over full crop cycles, which for permanent crops like almonds and pistachios can span decades.

Solum's structure emerged from a direct relationship with Harvard's endowment, and the firm is expected to raise additional capital from institutional limited partners seeking farmland exposure. The exact co-investment posture with external GPs is not publicly detailed, but the firm's pooled fund and separate-account structure is designed for institutional allocators rather than high-net-worth individuals. The operator-aligned model resembles the direct-separate-account frameworks preferred by pensions and endowments.

Water security is central to Solum's underwriting process. The firm explicitly evaluates each acquisition based on irreplaceable water rights and long-term aquifer sustainability, a discipline carried over from Harvard Management Company's direct-operations model. In drought-exposed regions like the San Joaquin Valley, the firm targets properties with senior water rights and invests in irrigation-efficiency upgrades as a core value-creation lever, rather than treating water as an externalized input cost.
