We use a combo of our own tool: Paymo - https://www.paymoapp.com https://www.paymoapp.com (i'm a co-founder) and Jira - https://www.atlassian.com/software/jira https://www.atlassian.com/software/jira There are tons of PM tools out there, with Paymo we try to cover a bunch of needs in the same tool, while keeping it simple. I sometimes hate the complexity of Jira, but at the moment it's better suited for certain projects then our own.
