S4 is a young company but the team behind it has a lot of experience in hosting, web design, development, and server management. We are passionate about sustainability, ethics, open source software, net neutrality and internet freedom.

We spent more than a year, and a lot of thought, work, testing and development before launching our services to create web hosting on our own terms. We've spent another year and a half since then, continuing to improve and evolve, happily offering the same hosting service to other people who need a web presence that works but also care about a sustainable, fast, and affordable internet.
