California leads the US eCommerce front, accounting for one-third of all online business in the country.
In San Francisco alone, there is a heavy concentration of technology-powered online stores, particularly in SaaS-powered commerce, subscription-based models, and B2B marketplaces. With US eCommerce sales expected to hit $1.38 trillion by 2026, Bay Area brands are increasingly prioritizing headless commerce, mobile-first UX, and data ownership.
Local businesses with more than 2.5 million small and mid-sized online merchants across the state are paying more attention to API-based integrations and long-term performance over off-the-shelf templates.
