These are the 12 industries Abstrakt's SDRs call for MSP work, with how many of each are in the Riverside-San Bernardino metro and who to ask for. No IT-buying category is markedly over-represented here, so the list should follow size and fit rather than one dominant industry. Wealth management and investment firms and law firms 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, real estate brokerages and property management offices, law firms and accounting, tax and bookkeeping firms run smaller, so those groups need a seat-count question before a meeting is booked.

• Construction contractors are the largest group in Riverside with 1,025 businesses of 20 to 499 employees, more than San Diego has (882): less concentrated than nationally (0.82x), up 315 establishments in a year, and typical in size (17% with 50 or more employees).

• Manufacturers are the second-largest group in Riverside with 991 businesses of 20 to 499 employees, more than San Diego has (673): less concentrated than nationally (0.69x), down 10 establishments in a year, and typical in size (31% with 50 or more employees).

• Medical, dental and outpatient practices are the third-largest group in Riverside with 846 businesses of 20 to 499 employees, more than San Diego has (773): less concentrated than nationally (0.85x), up 469 establishments in a year, and typical in size (12% with 50 or more employees).

• Wholesale distributors are the fourth-largest group in Riverside with 738 businesses of 20 to 499 employees, more than San Diego has (493): less concentrated than nationally (0.59x), up 72 establishments in a year, and typical in size (18% with 50 or more employees).

• Private schools and education providers are the fifth-largest group in Riverside with 168 businesses of 20 to 499 employees, fewer than San Diego has (330): less concentrated than nationally (0.50x), up 40 establishments in a year, and typical in size (22% with 50 or more employees).

• Nonprofits and member organizations are the sixth-largest group in Riverside with 160 businesses of 20 to 499 employees, fewer than San Diego has (251): less concentrated than nationally (0.43x), down 35 establishments in a year, and typical in size (16% with 50 or more employees).

After those six come architecture and engineering firms (114), real estate brokerages and property management offices (69), law firms (48), accounting, tax and bookkeeping firms (45), insurance agencies and brokerages (45) and wealth management and investment firms (8), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Riverside: manufacturers (991, CMMC where they supply defense work), medical, dental and outpatient practices (846, HIPAA), law firms (48, client security questionnaires), accounting, tax and bookkeeping firms (45, the FTC Safeguards Rule), insurance agencies and brokerages (45, carrier and state insurance data security requirements) and wealth management and investment firms (8, SEC and FINRA exams); together, 1,983 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.

539 IT services firms are based in the Riverside-San Bernardino metro. 57 more opened over the past year, so buyers are fielding new names. The IT services industry is 82% 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. 7.9 target businesses per IT firm puts Riverside 6 of 100 markets, and 2 of 11 in California. That is more room per IT firm than most metros, so systematic prospecting tends to find accounts nobody is working. Riverside has more target businesses per IT firm than the nearest markets.

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

San Bernardino County and Riverside County hold 100% of the target businesses across the 2-county metro.

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: 469 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: 315 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.

• Wholesale distributors: 72 more establishments than a year ago

  In this category the usual openings are an ERP or warehouse system change, a new warehouse, a cyber insurance renewal, an acquisition.

• Nonprofits and member organizations: 35 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.
