These are the 12 industries Abstrakt's SDRs call for MSP work, with how many of each are in the San Francisco-Oakland 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. Insurance agencies and brokerages and wholesale distributors are thinner than the national mix, so treat them as selective targets.

Insurance agencies and brokerages run larger in San Francisco than across our 100 metros, which puts more of them in Tier 1.

• Construction contractors are the largest group in San Francisco with 1,127 businesses of 20 to 499 employees, more than Stockton has (146): less concentrated than nationally (0.65x), up 137 establishments in a year, and typical in size (18% with 50 or more employees).

• Medical, dental and outpatient practices are the second-largest group in San Francisco with 1,060 businesses of 20 to 499 employees, more than Stockton has (121): less concentrated than nationally (0.82x), up 477 establishments in a year, and typical in size (16% with 50 or more employees).

• Manufacturers are the third-largest group in San Francisco with 810 businesses of 20 to 499 employees, more than Stockton has (188): less concentrated than nationally (0.57x), down 60 establishments in a year, and typical in size (28% with 50 or more employees).

• Wholesale distributors are the fourth-largest group in San Francisco with 766 businesses of 20 to 499 employees, more than Stockton has (144): less concentrated than nationally (0.45x), down 148 establishments in a year, and typical in size (19% with 50 or more employees).

• Private schools and education providers are the fifth-largest group in San Francisco with 653 businesses of 20 to 499 employees, more than Stockton has (36): close to the national mix, up 101 establishments in a year, and typical in size (21% with 50 or more employees).

After those six come architecture and engineering firms (366), wealth management and investment firms (318), law firms (289), real estate brokerages and property management offices (250), insurance agencies and brokerages (143) and accounting, tax and bookkeeping firms (119), smaller groups to work by fit rather than volume.

Where a rule or a client review puts a date on security work in San Francisco: medical, dental and outpatient practices (1,060, HIPAA), manufacturers (810, CMMC where they supply defense work), wealth management and investment firms (318, SEC and FINRA exams), law firms (289, client security questionnaires), insurance agencies and brokerages (143, carrier and state insurance data security requirements) and accounting, tax and bookkeeping firms (119, the FTC Safeguards Rule); together, 2,739 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.

2,802 IT services firms are based in the San Francisco-Oakland metro. 106 more opened over the past year, so buyers are fielding new names. The IT services industry is 30% 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. 2.3 target businesses per IT firm puts San Francisco 66 of 100 markets, and 10 of 11 in California. That sits mid-pack: real room to grow, but the best accounts are contested. If you can serve Stockton and Santa Cruz, they have more target businesses per IT firm than San Francisco.

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

Alameda County, San Francisco County and Contra Costa County hold 81% of the target businesses across the 5-county metro. The other 2 counties split the remaining 19%, 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: 477 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: 137 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.

• Private schools and education providers: 101 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: 148 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.
