MonkeyBrains is a San Francisco based ISP and has been in business since 1998. Rudy Rucker and Alex Menendez are the two monkeys who run the show. We offer a variety of services from high speed wireless connections to colocation. If your business is looking for an Internet presence, we can host your server, lease a server, or host your domain on a virtual server. If you are looking for Internet access, residents and businesses across the Mission and SoMa are hopping on our wireless network. Higher end needs can be met with a direct fiber connection from our data center to your business. The main home for our servers is 200 Paul Ave -- we can cross-connect to any provider and satisfy your IP needs - 1Mbps to 10Gbps. We'll give you a tour if you are interested.
