Acquia has yet to price its maintenance and support subscriptions - there should be a variety of SLAs - but they're supposed to include an electronic update notification system code named Spokes for updates that have been reviewed for security and compatibility and are supported by Acquia. Acquia is currently at 12 people, expecting to be 25 by the end of the year. Its Series A money comes from Northbridge Venture Partners, Sigma Partners and O'Reilly AlphaTech Ventures. According to Dries' blog, Drupal 7 should offer the ability to create, share and mashup managed content, letting Drupal be a data repository accessed by tools and web sites across the network.
