What I use to get stuff done
Here's a list of what I am currently using right now to accomplish my user research. Tools are all used accordingly for whatever task or analysis is needed and shared across teams.
UserTesting - App that provides on demand feedback, user recruiting, and user interviews.
As of the summer of 2015, I do not use UserTesting any more because they've changed their pricing model to an enterprise subscription model and no longer offer "pay as you go" un-moderated user testing. I now use UserTesting again at Helix to do quick-hit testing. I prefer doing remote moderated user tests through my own recruitment methods when it calls for in-person user tests.
Qualtrics - High end enterprise survey tool that has all the bells and whistle for complex logic. Used for high volume research or large distribution.
Typeform - My favorite free survey tool for getting high-response rate surveys via email or online posting for short no-frills surveys
Kissmetrics - Event-based analytics platform that measures what users do and don't do as they use cross from device to device
Optimizely - Optimization platform to run A/B tests to test hypotheses with the team after doing research and and coming up with informed ideas.
Google Analytics - Analytics platform to measure web traffic and marketing performance.
CrazyEgg - Heatmap tool to analyze hotspots of existing pages or apps.
Sketch - The new standard for designing just about anything in a lightweight or highly visual fashion.
