We’re fan-favorites.

You might’ve heard that we’re the best in town. (It’s true.) We’ve connected hundreds of happy customers and were voted a Neighborhood Fave by Nextdoor users in 2023. We’re proud to be among the highest-rated ISPs in the San Francisco Bay Area and Silicon Valley. Check out our Google and Yelp reviews to see for yourself.


We’re bridging the digital divide.

We aim to make the internet more accessible and affordable to those we serve. We empower our customers to break free from big cable with attractive packages and stellar customer service.


Delivering fast fiber services since 2015

Sail Internet was founded in 2015 by local innovators and Stanford alumni — Kevin Fisher, Ph.D. a former Engineering V.P. at 2Wire and Ikanos, and George Ginis, Ph.D., a former Engineering and Marketing V.P. at ASSIA.

Fueled by passion and growth

We’re dedicated to disrupting the traditional ISP industry and committed to bringing a better alternative to consumers and businesses in the areas we serve. Our team consists of growth-minded individuals, technology enthusiasts and net neutrality advocates.
