Compared with the U.S. as a whole, Baltimore-Columbia leans toward private schools and education providers (1.40x), nonprofits and member organizations (1.38x) and medical, dental and outpatient practices (1.25x).

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.

Private schools and education providers run larger in Baltimore than across our 100 metros, which puts more of them in Tier 1.

• Construction contractors are the largest group in Baltimore with 887 businesses of 20 to 499 employees, fewer than Washington has (1,608): close to the national mix, up 71 establishments in a year, and typical in size (19% with 50 or more employees).

• Medical, dental and outpatient practices are the second-largest group in Baltimore with 783 businesses of 20 to 499 employees, fewer than Washington has (1,563): more concentrated than nationally (1.25x), up 362 establishments in a year, and typical in size (14% with 50 or more employees).

• Wholesale distributors are the third-largest group in Baltimore with 547 businesses of 20 to 499 employees, fewer than Washington has (587): less concentrated than nationally (0.73x), down 28 establishments in a year, and typical in size (24% with 50 or more employees).

After those six come private schools and education providers (231), real estate brokerages and property management offices (129), law firms (103), insurance agencies and brokerages (85), accounting, tax and bookkeeping firms (82) and wealth management and investment firms (68), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Baltimore: medical, dental and outpatient practices (783, HIPAA), manufacturers (435, CMMC where they supply defense work), law firms (103, client security questionnaires), insurance agencies and brokerages (85, carrier and state insurance data security requirements), accounting, tax and bookkeeping firms (82, the FTC Safeguards Rule) and wealth management and investment firms (68, SEC and FINRA exams); together, 1,556 businesses where the first message can lead with the requirement instead of the service.

The 100-metro average is the same share summed across every market we publish.

2,184 IT services firms are based in the Baltimore-Columbia metro. 105 more opened over the past year, so buyers are fielding new names. The IT services industry is 1.5 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. 1.8 target businesses per IT firm puts Baltimore 78 of 100 markets. That is toward the crowded end, so growth here comes mostly from displacing incumbents at renewal. If you can serve Harrisburg and Philadelphia, they have more target businesses per IT firm than Baltimore.

Tier 1 covers construction contractors, medical, dental and outpatient practices and wholesale distributors with 50 to 499 employees.

Baltimore County, Baltimore city, Anne Arundel County and Howard County hold 87% of the target businesses across the 7-county metro. The other 3 counties split the remaining 13%, 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: 362 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: 157 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.

• Private schools and education providers: 93 more establishments than a year ago

  In this category the usual openings are a device refresh, a wireless upgrade, a new building, a summer project list, a security incident.

• Wholesale distributors: 28 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.

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