Tech companies in Los Angeles: two counties, two tech economies and 9,803 sites to choose from

This page is for readers who need Los Angeles tech companies as a list, not a ranking: a business choosing a developer or IT partner, a job seeker, an investor, or a B2B seller whose customers are tech firms. It covers the Census count for the two-county metro, the public companies in each county, the official data that names the rest and how to work through it.

How many tech companies are in Los Angeles

County Business Patterns (CBP), the Census Bureau's annual count of businesses with employees, puts 9,803 tech establishments in the Los Angeles-Long Beach-Anaheim, CA Metro Area (CBSA 31080) for 2023. Tech means four NAICS industry groups: software publishers (5112), computer systems design and related services (5415), data processing, hosting and related services (518) and other information services (5191).

Only the New York (14,579) and Washington, DC (12,541) metro areas have more tech establishments. Dallas-Fort Worth is fourth with 7,996.

Two counties, two tech economies

The two counties have about the same average site size (15 employees), but their public companies tell different stories. Ranked by revenue in each company's latest 10-K:

LA County's list is consumer apps, marketplaces and ad tech around Santa Monica, plus business software in Glendale and Woodland Hills. Orange County's largest are chips and electronics makers in Irvine and Santa Ana, the kind of company the Census Bureau counts as a manufacturer, so it's outside the 9,803. The Westside and Irvine are worth treating as separate territories.

One caution on growth: Los Angeles County's annual financial report shows Information sector employment, which here includes film and television, at 189,900 on 30 June 2025, down from 230,500 in 2016. Tech hiring in LA isn't a straight line up.

What kind of tech companies

Software publishers are the largest employer group, at about 40 employees per site. The 931 other information services establishments are mostly internet publishing and web search portals (859 sites, 24,910 employees): streaming, social and digital media companies that a software-only count would miss. The 3,565 custom programming firms average only eight employees, so most are small studios and agencies.

Size

In bands: 8,811 establishments with 1 to 19 employees, 734 with 20 to 99 and 258 with 100 or more. LA has more tech establishments than Dallas-Fort Worth but fewer large ones (Dallas has 266 with 100 or more).

Finding Los Angeles tech companies by name

The City listing is the most complete free list for the city itself. It uses current NAICS codes, so software publishers appear under 5132 and hosting under 5182 rather than the older codes in the Census table. For Santa Monica, Irvine and the rest of the region, use the state's business records.

Choosing an LA tech partner

Orange County's top-employer list hints at where the large buyers are: its 2025 financial report ranks The Walt Disney Co. first with 36,000 employees, followed by UC Irvine and Providence Southern California.

Prospecting Los Angeles tech companies

With 8,811 establishments under 20 employees, most of the LA market is owner-run and price-sensitive: short messages, clear pricing, quick trials. The 734 with 20 to 99 have functional leaders (marketing, engineering, operations) who buy within their budgets. The 258 with 100 or more add procurement. Split territories by county and corridor, and look for triggers such as a funding round, a product launch, a new studio or content partnership, and hiring.

Worked example: a product video studio

Illustrative example. The company, people and rates are fictional, to show the method.

Marquee Demo Studio (marqueedemo.example) makes product demo and explainer videos for software companies, using LA crews. It targets software publishers and programming firms with 10 to 99 employees in both counties.

• Establishments with 10 to 99 employees: 708 + 503 + 231 = 1,442.
• Software publishers and custom programmers are 4,584 of 9,803 establishments (47%), so about 675 of those 1,442.
• Marquee assumes a quarter sell a product with a self-serve trial, where demo videos matter most: about 170 accounts.
• At 40 a month and a 6% reply-to-meeting rate, that's two or three meetings a month.

Telling product companies from agencies means reading every website. Bebop takes "Los Angeles and Orange County software companies with 10 to 99 employees that offer a free trial" and returns matches with a playbook for each.

What the count covers

CBP counts establishments, single locations with at least one paid employee, for the week of March 12, 2023. A company with offices in Santa Monica and Irvine counts twice, freelancers aren't counted, and tech teams at studios, aerospace firms and retailers count under their employers' industries.
