Monument Square Investment Group

Managing Partner Benjamin Poirier leads the firm, supported by Partner D. Tyler Steindorf (Investments) and Managing Director Matthew Doherty. The firm stresses centralized decision-making, which it describes as enabling nimble execution in complex transactions.

MSIG targets the highly fragmented middle and lower-middle US real estate market, sourcing opportunities directly and through its network of more than 30 institutional joint-venture partners. The firm operates across three verticals — rental housing, industrial and logistics, and special situations — often pursuing off-market or complex situations where its single-decision-layer structure provides an edge.

It operates as a privately held alternative investment manager, not a family office. The firm raises and deploys capital through joint ventures with institutional sponsors rather than managing a single family's balance sheet.

The firm focuses on direct real estate acquisitions and tactical joint ventures. Its public materials describe programmatic co-GP platforms inside the special-situations vertical, but do not indicate any fund-of-funds or LP commitments to external managers.

The special-situations vertical pursues distressed and non-performing assets and loans, programmatic co-GP platforms, covered land investments, and sectors or MSAs the firm views as mispriced. It targets value-add, development, redevelopment, adaptive re-use, and land-entitlement profiles.

MSIG concentrates on the United States. Rental housing targets suburban primary MSAs and infill secondary and select tertiary markets, plus tier-I university towns. Industrial focuses on logistics clusters near major ports, interstates, and population centers. Special situations are generally MSA-agnostic with a preference for primary and secondary markets with strong fundamentals.
