If you launch a product to a few different countries, does it make sense to do usability testing in all those different countries?

Are you talking about actual design mockups (PSD files etc) or just directional sketches that will help illustrate ideas you're having about how to improve the pages? If leaning more towards the former, I'd put yourself in a position to not need anyone else necessarily and just focus on creating wireframe mockups of the pages (no typography or finalization of icons/the skin of the page) and start with the blocking and tackling of each page. wireframing it also let's you more easily bifurcate between the web and mobile UX (if that is a part of what you've identified as an area that can be improved upon) - plus in my experience wireframes give you more of a blank canvas to start with while not narrowing your possible ideation phase with already in-place icons or imagery - basically it lets you work from the feet up each page. Taking this step (with wireframes first) allows you to revise and iterate on your ideas and THEN go find someone to produce mockups/design files in a more streamlined fashion (you dont want to be creating and constantly editing full design iterations as that would be a heavier, cumbersome and most costly process.) I've also found the narration process around wireframes much smoother and easier for inviting other contributors and capturing the commentary of the "why" to go with your "what". Good luck, feel free to reach out if you need any other suggestions or walk to talk through options!

Based on my own experience building indie games I'd recommend these Reddit and Slack channels for beta testing: Reddit: https://www.reddit.com/r/AlphaAndBetaUsers https://www.reddit.com/r/playmygame https://www.reddit.com/r/indiegameswap/ https://www.reddit.com/r/freegames Slack: https://www.hamsterpad.com/chat/hashtaggaming https://www.hamsterpad.com/chat/gamedevelopment https://www.hamsterpad.com/chat/indie-game-devs Also, just give it to your friends and family and you can record their interactions with it using something like: https://www.lookback.io/ Finally, some paid options include: https://www.usertesting.com http://ubertesters.com/ https://betafamily.com/ If you want to discuss how best to design customer interviews / questionnaires for your specific app, to assess what you need to change, what to keep, etc. feel free to send me a message, best, Lee

You're on the right track. I'm glad to see you getting the steps in the right order. WHO are potential users of your product? WHAT problem(s) will your app potentially be solving for them? HOW much do these potential users value the solution of these problems? Find your user group of people who would pay for a solution to a problem your app will solve. Get their input. I would do this through a couple stages...the first involving live talking, and the second usage of a basic version of the app once you and they have figured out what its purpose is.

Look on Google Communities for technology focused BETA testing groups... Look on Linkedin Groups for business focused potential testers... Look on Facebook Pages for people who like apps/companies like what you are trying to bring to market... That should get you started.

Create an ideal customer profile. Create some questions that will allow to you survey a potential tester to determine if they fit your profile. Design simple landing page with very clear value proposition that speaks to your ideal customer. Ask for a minimum of information up-front (email), but ask for more info after they commit by submitting the first piece of info. (KISSmetrics does a good job of this on their current website trial signup). Use the their answers to these profiling questions to put the applicants into buckets. Let in the most ideal bucket first, or split them into groups if they're big enough. Try and measure engagement the best you can. Measure qualitative and quantitative data. Schedule calls with your beta testers to find out more, especially with the ones who's user behavior seemed to indicate that they didn't get value from your product. Find out why. Make sure they are indeed your ideal customer. Pick up the phone and get to know your customers inside and out. Meet them in person if possible. Incorporate their feedback quickly and get more feedback. Rinse repeat.
