We use a suite of tools, essentially pivotal for tracking work, trello for tracking user feature requests, heap and mixpanel for tracking usage and funnel progression, botkeeper for bookkeeping along with quickbooks, sentry for tracking errors and segment.io for piping data to 3 party services from our various systems. For user testing we use vempathy, and for market research we use surveymonkey or google surveys.
