Ask HN: Does a Hacker-friendly CRM exist?

Here's what we're looking for:

  1. A strong API and flexible data model that will let us:
     - Create and update records with events and data from 
       our production system.
     - Pull records, events, and aggregate statistics stored
       in the CRM.
     - Export all data and get out if we hate it.

  2.  A web-based interface that makes it a pleasure to 
      interact with the stored records, events, and aggregate 
      statistics.

  3. Seamless integration with Gmail
     - We use Gmail as our primary sales and support channel.     
       Without taking any explicit action, the CRM should 
       consume those messages so that emails become    
       associated with the appropriate customer & contact    
       records.
     - We should also be able to forward email to the system 
       (e.g. from personal email accounts) and get those 
       emails associated as well.

  4. Many-to-many associations between people and customers,
     i.e.:
     - I will correspond with multiple people at a given 
       company using our product; I should be able to see 
       those interactions in one place.
     - Some people may be associated with multiple customers, 
       perhaps because they have changed jobs or because they 
       are consultants serving multiple clients.

  5. Customizable deal stages
     - Again, set a customer's stage via API.
     - Aggregate view of sales pipeline.

  6. MOST IMPORTANT: MINIMIZE FRUSTRATION
     - Won't make an engineering-heavy team punch the walls 
       and demand to build their own.
     - Won't require duplicate entry between CRM and other
       systems.
     - Won't require lots of time servicing the damn thing.
