ADDITIONAL BACKGROUND
The Capacity Building Mentorship Program (CBMP) is a long-term effort by the Washington
State Department of Transportation (WSDOT) to strengthen the capacity of small businesses in
Washington by connecting them with larger firms engaged in government construction and
consulting projects. Since its inauguration, the Program has promoted building relationships
and expanding contracting opportunities as the most effective way to strengthen the capacity
of Small Businesses. Since its launch in 2018, more than 130 protégés have participated in this
program in one of seven cohorts, with over 88% of mentors and proteges in the most recent
cohorts reporting being satisfied or very satisfied with the program.
The Program was originally launched in March 2018 through a partnership between WSDOT,
the American Council of Engineering Companies (ACEC), and the Associated General
Contractors of Washington (AGC), with Thor Construction serving as program manager. In April
2019, it was relaunched as the Capacity Building Mentorship Program in partnership with
Sound Transit, ACEC, AGC, and the Washington Minority Business Development Agency (MBDA)
Business Center.
On June 30, 2025, the WA MBDA Business Center closed. To ensure continuity, WSDOT hired
CORE Strategists to manage the program during this period. WSDOT has selected a long-term
CBMP program administrator, Apex Accelerators, that began work in January 2026.
Differentiation from Port Business Accelerator Program
Diversity in Contracting has organized its own mentorship program, the Port of Seattle Small
Business Accelerator Mentorship Program, since 2021. This program occurs annually in the Fall
wherein 11-15 select businesses in Port-related industries, are each paired with an industry
mentor and experience a robust curriculum, primarily in-person, over the course of three
months. The Program is known for the unique visibility and access it grants these businesses to
the Port, by connecting them to key Port decision makers, and educating them on the Port’s
unique contracting opportunities and needs. It is also singular in its ability to establish
meaningful relationships, and a sense of community among the cohort businesses and their
