Sail Internet is a Santa Clara-based internet service provider that uses a hybrid of fiber and fixed-wireless technology to deliver high-speed, no-contract broadband to homes and businesses across the San Francisco Bay Area and Silicon Valley. Founded in 2015 by Stanford-trained broadband engineers, the company positions itself as a customer-first, net-neutral alternative to incumbent cable and telecom giants, reaching residences, multi-dwelling communities, and enterprises with gigabit-class connectivity that skips costly trench-and-dig infrastructure.
Sonic is the largest independently owned internet service provider in California, founded in 1994 in Santa Rosa. It builds and runs its own fiber-optic network, selling fast, flat-priced gigabit and 10-gigabit home and business internet with no contracts, no data caps, and a privacy stance that has earned it a perfect score from the Electronic Frontier Foundation. After more than 30 years serving the San Francisco Bay Area, Sonic began its first out-of-region expansion in 2026, lighting up fiber in Los Angeles and Dallas.
