But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.

Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)

Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
