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.

Manufacturers and insurance agencies and brokerages run larger in Milwaukee than across our 100 metros, which puts more of them in Tier 1. Wealth management and investment firms run smaller, so that group needs a seat-count question before a meeting is booked.

• Manufacturers are the largest group in Milwaukee with 934 businesses of 20 to 499 employees, fewer than Chicago has (3,168): more concentrated than nationally (1.34x), down 71 establishments in a year, and larger than across our 100 metros (41% of those with 10 or more employees have 50 or more, against 32%), so plan on two or three contacts per account.

• Medical, dental and outpatient practices are the second-largest group in Milwaukee with 515 businesses of 20 to 499 employees, fewer than Chicago has (2,150): close to the national mix, up 150 establishments in a year, and typical in size (17% with 50 or more employees).

• Wholesale distributors are the third-largest group in Milwaukee with 434 businesses of 20 to 499 employees, fewer than Chicago has (2,273): close to the national mix, up 39 establishments in a year, and typical in size (23% with 50 or more employees).

• Construction contractors are the fourth-largest group in Milwaukee with 378 businesses of 20 to 499 employees, fewer than Chicago has (1,695): less concentrated than nationally (0.87x), up 59 establishments in a year, and typical in size (19% with 50 or more employees).

• Nonprofits and member organizations are the fifth-largest group in Milwaukee with 206 businesses of 20 to 499 employees, fewer than Chicago has (896): less concentrated than nationally (0.74x), down 5 establishments in a year, and typical in size (13% with 50 or more employees).

• Private schools and education providers are the sixth-largest group in Milwaukee with 183 businesses of 20 to 499 employees, fewer than Chicago has (853): less concentrated than nationally (0.87x), up 8 establishments in a year, and typical in size (29% with 50 or more employees).

After those six come architecture and engineering firms (100), real estate brokerages and property management offices (82), law firms (65), accounting, tax and bookkeeping firms (58), insurance agencies and brokerages (49) and wealth management and investment firms (48), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Milwaukee: manufacturers (934, CMMC where they supply defense work), medical, dental and outpatient practices (515, HIPAA), law firms (65, client security questionnaires), accounting, tax and bookkeeping firms (58, the FTC Safeguards Rule), insurance agencies and brokerages (49, carrier and state insurance data security requirements) and wealth management and investment firms (48, SEC and FINRA exams); together, 1,669 businesses where the first message can lead with the requirement instead of the service.

What leads in each core county

• Milwaukee County: manufacturers (350), medical, dental and outpatient practices (311) and wholesale distributors (170) lead its 1,424 target businesses.
• Waukesha County: manufacturers (355), construction contractors (204) and wholesale distributors (202) lead its 1,136 target businesses.

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.

577 IT services firms are based in the Milwaukee-Waukesha metro. 19 more opened over the past year, so buyers are fielding new names. The IT services industry is 37% 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. 5.3 target businesses per IT firm puts Milwaukee 16 of 100 markets, and 1 of 2 in Wisconsin. That is more room per IT firm than most metros, so systematic prospecting tends to find accounts nobody is working. If you can serve South Bend and Grand Rapids, they have more target businesses per IT firm than Milwaukee.

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

Milwaukee County and Waukesha County hold 85% of the target businesses across the 4-county metro. The other 2 counties split the remaining 15%, 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: 150 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.

• Construction contractors: 59 more establishments than a year ago

  In this category the usual openings are office growth, a new branch, job site connectivity problems, a wire fraud attempt, a cyber insurance renewal.

• Real estate brokerages and property management offices: 44 more establishments than a year ago

  In this category the usual openings are a wire fraud attempt, a new office, agent growth, a change in property management software.

• Manufacturers: 71 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.
