If you’d like to work with another worker cooperative, our number one recommendation is to check out the Tech Co-op Network, but here are some specific referrals to providers we are familiar with:
Domain registration: We recommend GKG, as they are affordable, their online systems are well-organized and straightforward, and they provide quality customer support.
Web site design, development, and maintenance: Design Action Collective (Oakland) is a worker coop specializing in graphic design, visual communications, and web site development for progressive organizations. We also like FivePaths (Bay Area), Sassafras Tech Collective (Ann Arbor), C4 Tech & Design (New Orleans), and Palante Technology Cooperative (New York).
Web strategy: Aspiration (San Francisco) is a great resource for technology planning/process help and RFP design.
Other hosting services: For server colocation or virtual server hosting, try our colo provider, MonkeyBrains (San Francisco).
Newsletter/CRM service: If you need message personalization, list segmentation, open rate tracking, and such, check out the Salsa platform or Campaigner, or take a look at this excellent survey of other providers as of January 2012 put together by our friends at Groundwire.
Computer service and data recovery: In San Francisco, trust TechCollective.
