Salt Lake City has emerged in 2026 as a thriving tech and startup powerhouse with an ecosystem now ranked #40 globally. Home to over 760 active startups, the city’s tech sector grew by more than 22% last year, with total startup funding surpassing $1.32 billion and continued interest from major VC firms like Run Ventures, which launched a $290 million fund for early-stage technology companies in 2025.
Salt Lake City’s “Silicon Slopes” reputation is backed by a highly educated workforce – over 67,000 tech professionals in the metro area, 34% above the national average, and a strong talent pipeline from local universities such as the University of Utah. Startups specializing in AI, SaaS, fintech, healthtech, and climate innovation are drawn by competitive costs, quality of life, and supportive city programs such as the Economic Development Loan Fund, which will expand in 2026 to offer flexible loans for new businesses, including energy-efficient upgrades and marketing.
