97 California manufacturers clear both bars: more than 25 employees and founded by 2021

Asked:

“manufacturers in california that are over 25 employees and 4 years old.”

A live-web scan surfaced 97 California manufacturers whose cited source states an employee count or range proving more than 25 employees and a founding year of 2021 or earlier — a conservative year-level test for being over four years old as of October 2026. The list spans meat and food processing, packaging, aerospace, electronics, medical devices, apparel, and industrial products across 64 California cities.

This is a sourced prospect list, not a census: no complete authoritative statewide universe exists, so more qualifying manufacturers surely exist. Evidence is concentrated — 76 of 97 rows come from six Inven.ai category pages — and reported headcounts are company-wide figures that may include staff outside California.

Southern California dominates: Los Angeles County alone (Industry, Commerce, Vernon, Los Angeles and neighbours) and San Diego County each hold sizeable clusters, led by City of Industry and San Diego with 6 companies apiece — e.g. inven.ai.
Meat and protein processing is the single largest focus (21 of 97), ahead of food & beverage (15), packaging (14) and aerospace & defense (14) — inven.ai.
Most entries are mid-sized: 39 report 51–200 employees, while 15 prove more than 1,000 — the largest being Viasat in Carlsbad at over 8,000 — grokipedia.com.
These are long-lived firms: median approximate age is 43 years, the youngest is 7 (well past the 4-year bar) and the oldest, Ducommun of Costa Mesa, dates to 1849 — revenuebase.ai.

Reported employee counts are company headcount as stated by the source and may be worldwide, not California-site employment.

Method: live-web scan compiled 2026-10-19; 97 rows, one per normalized company, each citing one of 21 source URLs on 10 hosts; the largest single URL supports 22 rows (22.7%) and six Inven.ai category pages supply 76 rows. Inclusion required a stated employee count or range proving >25 employees and a founding year ≤2021 (a conservative year-level proxy for >4 years old). Employee figures are reported company headcount, possibly worldwide; ages are approximate from founding year. Map dots use standard city coordinates since sources carry no latitude/longitude; detailed location notes were shortened for space.
