Question
I have a mobile app that is doing decent now with couple of million installs.
I am now planning to get few people who are good with product design, user experience design, etc. to get some fresh eyes to make the app better.
How would you recommend looking for people with the required skill sets?
Answer
My first question is Why do you *think* your UI/UX needs updating? Now, I am not suggesting it doesn't, but wanting something and needing something are two separate things. So hopefully you are taking a holistic approach, looking at your user behavior patterns, and identifying possible issues to improve upon.
As far as finding the right people. I would recommend either looking at small agencies (a google search is a good place to start) or using LinkedIn to find individuals to talk/interview.
