These are the 12 industries Abstrakt's SDRs call for MSP work, with how many of each are in the Washington-Arlington metro and who to ask for. Compared with the U.S. as a whole, Washington-Arlington leans toward nonprofits and member organizations (2.33x), private schools and education providers (1.51x) and law firms (1.20x). Build the list around those categories. Manufacturers and wholesale distributors are thinner than the national mix, so treat them as selective targets.

Businesses are establishments with 20 to 499 employees (U.S. Census Bureau, County Business Patterns 2023), the small and mid-sized range MSPs sell to; the SBA Office of Advocacy counts firms under 500 employees as small businesses.

Nonprofits and member organizations and law firms run larger in Washington than across our 100 metros, which puts more of them in Tier 1. Manufacturers run smaller, so that group needs a seat-count question before a meeting is booked.

• Construction contractors are the largest group in Washington with 1,608 businesses of 20 to 499 employees, more than Baltimore has (887): less concentrated than nationally (0.82x), down 217 establishments in a year, and typical in size (23% with 50 or more employees).

• Medical, dental and outpatient practices are the second-largest group in Washington with 1,563 businesses of 20 to 499 employees, more than Baltimore has (783): close to the national mix, up 585 establishments in a year, and typical in size (14% with 50 or more employees).

• Nonprofits and member organizations are the third-largest group in Washington with 1,453 businesses of 20 to 499 employees, more than Baltimore has (273): more concentrated than nationally (2.33x), down 126 establishments in a year, and larger than across our 100 metros (22% of those with 10 or more employees have 50 or more, against 15%), so plan on two or three contacts per account.

• Private schools and education providers are the fourth-largest group in Washington with 699 businesses of 20 to 499 employees, more than Baltimore has (231): more concentrated than nationally (1.51x), up 40 establishments in a year, and typical in size (26% with 50 or more employees).

• Architecture and engineering firms are the fifth-largest group in Washington with 675 businesses of 20 to 499 employees, more than Baltimore has (275): close to the national mix, down 16 establishments in a year, and typical in size (26% with 50 or more employees).

• Wholesale distributors are the sixth-largest group in Washington with 587 businesses of 20 to 499 employees, more than Baltimore has (547): less concentrated than nationally (0.53x), down 127 establishments in a year, and typical in size (20% with 50 or more employees).

After those six come manufacturers (424), law firms (408), real estate brokerages and property management offices (355), accounting, tax and bookkeeping firms (169), wealth management and investment firms (158) and insurance agencies and brokerages (98), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Washington: medical, dental and outpatient practices (1,563, HIPAA), manufacturers (424, CMMC where they supply defense work), law firms (408, client security questionnaires), accounting, tax and bookkeeping firms (169, the FTC Safeguards Rule), wealth management and investment firms (158, SEC and FINRA exams) and insurance agencies and brokerages (98, carrier and state insurance data security requirements); together, 2,820 businesses where the first message can lead with the requirement instead of the service.

Employee bands: U.S. Census Bureau, County Business Patterns 2023, establishments with 10 to 499 employees; suppressed size classes count as zero. Concentration and one-year change: U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages, private ownership, 2025 Q2. The 100-metro average is the same share summed across every market we publish.

10,134 IT services firms are based in the Washington-Arlington metro. That is 240 fewer than a year ago. When an IT firm closes or sells, its customers go looking for a new one. The IT services industry is 2.5 times the national concentration. Business owners and office managers here already hear from managed service providers, and a specific reason to talk beats a generic pitch. 0.8 target businesses per IT firm puts Washington 99 of 100 markets. That is toward the crowded end, so growth here comes mostly from displacing incumbents at renewal. If you can serve Baltimore and Harrisburg, they have more target businesses per IT firm than Washington.

Tier 1 covers construction contractors, medical, dental and outpatient practices and nonprofits and member organizations with 50 to 499 employees.

District of Columbia, Fairfax County, Montgomery County, Prince George's County, Loudoun County and Prince William County hold 80% of the target businesses across the 22-county metro. The other 16 counties split the remaining 20%, which is where Tier 1 accounts justify the drive and smaller sites do not.

A new office or location needs network, devices and security set up before people move in, and the provider who does that work is in the best position to support it after.

• Medical, dental and outpatient practices: 585 more establishments than a year ago

  In this category the usual openings are a new location, a HIPAA risk assessment, an EHR or practice management change, a security incident.

• Manufacturers: 72 more establishments than a year ago

  In this category the usual openings are an ERP upgrade, a ransomware incident in the industry, a defense supplier CMMC requirement, a new line or facility.

• Wealth management and investment firms: 41 more establishments than a year ago

  In this category the usual openings are a regulatory exam, a custodian or broker-dealer requirement, a firm breakaway or merger, a security incident.

• Construction contractors: 217 fewer establishments than a year ago

  An acquisition puts a business under new owners, who usually review who runs IT and fold it into their own systems.

• 240 fewer managed service providers than a year ago

  Clients of an IT firm that closed, retired or sold have to decide who supports them next.

More questions for every prospect type, and how to follow up after the meeting, are in the MSP prospecting playbook.
