Any CRM plugin like the 17hats from WPMU?

Hi,
Is there any CRM plugin that works like 17hats (https://www.17hats.com ) created by WPMU? Or how possible is WPMU to create an intuitive business management software like 17hats? Or what type of CRM/Business Management Software do WPMU use to manage its teeming clients?

Thanks in anticipation.

Best Regards
