Pipedrive is a good pre-sales CRM. The problem arises when you have to manage pre-sale leads into sale. I have not found a good CRM that does that. I used Nutshell before and we had the same problem.
Gaiku allows you to manage meetings pre- and post-meeting arrangements. For example, it sends Apple reminders or Trello tasks into the meeting automatically. It’s a tool that allows you to resolve the meeting freeze by keeping meetings organized and on topic.
Harvest is a really easy time tracking tool. You can connect it with JIRA and Trello.
