Fractional CFO and Controller services for St. Louis-area operating companies.
Vessel Advisors serves operating companies across Metro St. Louis, St. Charles County, and Metro East Illinois — aerospace and defense suppliers, agtech and agri-food operators, healthcare and life sciences services, industrial manufacturers, and family-owned mid-market operators . Our team includes CFOs and Controllers local to St. Louis, backed by a vetted national bench of senior finance leaders who parachute in when scope demands it.
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.

The Financial Discovery Assessment™ shows you what’s working, what’s missing, and the plan to get where the business needs to go.
Every Assessment applies the same structured examination — accounting systems and technology, processes and procedures, team members and team structure, and team-member will-skill — refined across hundreds of engagements in businesses that look like yours.
The output is the Financial Heat Map System™: dollarized findings, hidden inefficiencies, and a sequenced plan. It’s presented at the Executive Action Meeting, where your stakeholders review findings and recommendations in non-clinical, non-technical language they can act on.
We’ve walked into hundreds of businesses at the stage yours is in now. We know where to look. We know how to fix what we find.
