Founded in 1996 by two groups of engineers, Black River Systems grew from a small research team into an employee-owned company with more than 100 staff members. The Utica-based firm is known for moving advanced sensing work from research into fielded systems, particularly for government and defense customers, while its employee ownership—established through an ESOP in 2022—keeps the engineers who build and support those systems invested in the result.
