Feedback from users is invaluable building any kind of product/course/app.
Would love to hear how you're going about it, whether it's cold emailing, feedback widgets, app store reviews, or anything!
I literally ping on LinkedIn to my prospect users and ask them to if we can connect over a call to discuss about my startup and pain points of industry I am catering to.
If they say yes kudos!
If Naah Then I ask them if they can just text in short about their issues.
If nothing works then switch to next user.
I did use Survey and slightly it helped me.
imho... there is no substitute for phone conversations. Data collected via surveys or feedback widgets can help discover technical issues or key points of frustration. But broad, open-ended conversations tell you what to build and how to connect with new customers.
i've also found that prospective users / customers are more honest (true of higher price point Saas) about what they want than customers, because they are being asked to take a risk.
my approach is to ask for a 15-30 minute call (so they know you want suck their time away) and stick to it. if they enjoy the call, they will give you more time if you need it.
At csvbox.io we use the hubspot chat widget as the primary source of talking to the users and getting feedback.
At Gossip (https://thegossip.app) we ask users to post gossips with #appfeedback or #feedback so we can quickly look it up.
I agree with @martyb, I generally stick to video or phone calls. In some situations, I've done in person shadowing or interviews where appropriate.
I track user feedback in a Notion sheet and am building an app Navana to help collect and act on user feedback.
