Eastern Missouri and Metro East

We have team members local to the region and work across Eastern Missouri regularly.
St. Louis has one of the country's most industry-diverse mid-markets. Aerospace and defense anchored by Boeing, an agtech and agri-food cluster built around the Bayer / former Monsanto ecosystem, deep healthcare and life sciences infrastructure, and a family-owned industrial and distribution base that goes generations deep.

The Market
St. Louis's operating base is more industry-diverse than the outside narrative captures — aerospace, agtech, life sciences, and industrials all sit in the same mid-market.
Eastern Missouri's mid-market runs across four distinct industrial clusters. Aerospace and defense — anchored by Boeing's St. Louis operations — supports a deep bench of tier 2 and tier 3 suppliers, precision manufacturers, and defense services operators. The agtech and agri-food cluster around Chesterfield and Creve Coeur (the Bayer / former Monsanto ecosystem) supports specialty seed, biotech ag, and food ingredient operators. Healthcare and life sciences infrastructure spans BJC, Ascension, and Washington University, with a large healthcare services and health-tech operating base beneath them. And multi-generational family-owned industrial manufacturing and distribution runs throughout.
Finance-function work here reflects the diversity. Aerospace and defense suppliers need program economics, indirect rate management, and DCAA-adjacent reporting. Agtech and agri-food operators need milestone contracts, licensing revenue, and commodity exposure planning. Healthcare services businesses need payor contracting and revenue cycle rigor. And family-owned industrials often need to modernize reporting for a generational transition or first sponsor conversation.
What we see most:
- Tier 2 and tier 3 aerospace and defense suppliers, precision manufacturers, and defense services operators.
- Agtech, specialty seed, biotech ag, and food ingredient operators in the Chesterfield / Creve Coeur cluster.
- Healthcare services, life sciences suppliers, and health-tech operators in the BJC / Ascension / WashU ecosystem.
- Multi-generational family-owned industrial manufacturers and distribution operators.
- PE-backed platforms rolling up services, industrials, and specialty food across the Midwest.
- Construction contractors and specialty trades serving the regional build-out.
