These are the 12 industries Abstrakt's SDRs call for MSP work, with how many of each are in the Harrisburg-Carlisle metro and who to ask for. Compared with the U.S. as a whole, Harrisburg-Carlisle leans toward nonprofits and member organizations (2.18x) and medical, dental and outpatient practices (1.30x). Build the list around those categories. Wholesale distributors and real estate brokerages and property management offices 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. Change and concentration: U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages, private ownership, 2025 Q2.

Architecture and engineering firms run larger in Harrisburg than across our 100 metros, which puts more of them in Tier 1. Private schools and education providers, accounting, tax and bookkeeping firms, law firms and real estate brokerages and property management offices run smaller, so those groups need a seat-count question before a meeting is booked.

• Medical, dental and outpatient practices are the largest group in Harrisburg with 270 businesses of 20 to 499 employees, fewer than Baltimore has (783): more concentrated than nationally (1.30x), up 73 establishments in a year, and typical in size (18% with 50 or more employees).

• Construction contractors are the second-largest group in Harrisburg with 131 businesses of 20 to 499 employees, fewer than Baltimore has (887): close to the national mix, up 7 establishments in a year, and typical in size (20% with 50 or more employees).

• Manufacturers are the third-largest group in Harrisburg with 127 businesses of 20 to 499 employees, fewer than Baltimore has (435): close to the national mix, up 6 establishments in a year, and typical in size (31% with 50 or more employees).

• Wholesale distributors are the fourth-largest group in Harrisburg with 119 businesses of 20 to 499 employees, fewer than Baltimore has (547): less concentrated than nationally (0.74x), down 14 establishments in a year, and typical in size (23% with 50 or more employees).

• Nonprofits and member organizations are the fifth-largest group in Harrisburg with 93 businesses of 20 to 499 employees, fewer than Baltimore has (273): more concentrated than nationally (2.18x), down 6 establishments in a year, and typical in size (14% with 50 or more employees).

• Architecture and engineering firms are the sixth-largest group in Harrisburg with 50 businesses of 20 to 499 employees, fewer than Baltimore has (275): close to the national mix, up 8 establishments in a year, and larger than across our 100 metros (27% of those with 10 or more employees have 50 or more, against 22%), so plan on two or three contacts per account.

After those six come private schools and education providers (47), accounting, tax and bookkeeping firms (29), insurance agencies and brokerages (28), law firms (26), real estate brokerages and property management offices (11) and wealth management and investment firms (4), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Harrisburg: medical, dental and outpatient practices (270, HIPAA), manufacturers (127, CMMC where they supply defense work), accounting, tax and bookkeeping firms (29, the FTC Safeguards Rule), insurance agencies and brokerages (28, carrier and state insurance data security requirements), law firms (26, client security questionnaires) and wealth management and investment firms (4, SEC and FINRA exams); together, 484 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.

224 IT services firms are based in the Harrisburg-Carlisle metro. 17 more opened over the past year, so buyers are fielding new names. The IT services industry is 20% less concentrated than the U.S. as a whole, so a consistent outbound program reaches business owners and office managers that are not tired of contractor calls. 4.2 target businesses per IT firm puts Harrisburg 26 of 100 markets, and 3 of 4 in Pennsylvania. That is more room per IT firm than most metros, so systematic prospecting tends to find accounts nobody is working. If you can serve Allentown, it has more target businesses per IT firm than Harrisburg.

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

Dauphin County and Cumberland County hold 99% of the target businesses across the 3-county metro. The other 1 county splits the remaining 1%, 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: 73 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.

• Private schools and education providers: 11 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.

• Architecture and engineering firms: 8 more establishments than a year ago

  In this category the usual openings are slow file access, a workstation refresh, a new office, a client or government security requirement.

• Wholesale distributors: 14 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.
