These are the 12 industries Abstrakt's SDRs call for MSP work, with how many of each are in the Los Angeles-Long Beach 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. Construction contractors and nonprofits and member organizations 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.

Every industry here has a size mix close to the 100-metro average, so the tiers follow the counts.

• Manufacturers are the largest group in Los Angeles with 3,532 businesses of 20 to 499 employees, more than San Diego has (673): less concentrated than nationally (0.71x), down 250 establishments in a year, and typical in size (28% with 50 or more employees).

• Wholesale distributors are the second-largest group in Los Angeles with 3,221 businesses of 20 to 499 employees, more than San Diego has (493): less concentrated than nationally (0.71x), down 248 establishments in a year, and typical in size (17% with 50 or more employees).

• Medical, dental and outpatient practices are the third-largest group in Los Angeles with 3,092 businesses of 20 to 499 employees, more than San Diego has (773): close to the national mix, up 1,958 establishments in a year, and typical in size (13% with 50 or more employees).

• Construction contractors are the fourth-largest group in Los Angeles with 2,344 businesses of 20 to 499 employees, more than San Diego has (882): less concentrated than nationally (0.50x), up 800 establishments in a year, and typical in size (18% with 50 or more employees).

After those six come law firms (792), real estate brokerages and property management offices (697), architecture and engineering firms (648), accounting, tax and bookkeeping firms (352), insurance agencies and brokerages (331) and wealth management and investment firms (301), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in Los Angeles: manufacturers (3,532, CMMC where they supply defense work), medical, dental and outpatient practices (3,092, HIPAA), law firms (792, client security questionnaires), accounting, tax and bookkeeping firms (352, the FTC Safeguards Rule), insurance agencies and brokerages (331, carrier and state insurance data security requirements) and wealth management and investment firms (301, SEC and FINRA exams); together, 8,400 businesses where the first message can lead with the requirement instead of the service.

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.

4,130 IT services firms are based in the Los Angeles-Long Beach metro. 167 more opened over the past year, so buyers are fielding new names. The IT services industry is 69% 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 Los Angeles 24 of 100 markets, and 7 of 11 in California. That is more room per IT firm than most metros, so systematic prospecting tends to find accounts nobody is working. If you can serve Oxnard and Riverside, they have more target businesses per IT firm than Los Angeles.

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

Los Angeles County and Orange 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: 1958 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: 800 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.

• Law firms: 230 more establishments than a year ago

  In this category the usual openings are a phishing incident, a client security questionnaire, a new office or partner group, a document management change.

• Manufacturers: 250 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.
