Here are some providers whose work we trust, many of which are worker cooperatives too:
Web site design, development, and maintenance: Design Action Collective is a worker coop specializing in graphic design, visual communications, and web site development for progressive organizations. We also like FivePaths, EcoTechie, Sassafras Tech Collective, C4 / Tech Collective, Palante Technology Cooperative, and Benjamin Kite.
Web strategy: Aspiration is a great resource for technology planning/process help and RFP design.
Newsletter/CRM service: If you need message personalization, list segmentation, open rate tracking, and such, check out the Salsa platform or Campaigner.
IT consulting and support, computer service, data recovery: We have a lot of respect for Tech Underground, Giant Rabbit, C4 / TechCollective, Sassafras, Palante Technology Cooperative, and Alternative Technologies.
Local San Francisco ISPs: Try MonkeyBrains, Sonic or Astound, depending on your exact needs and location.
