Years ago I attended a UX Australia conference, and albeit not getting many takeaways from an insufferable bunch of communists, I left with a huge feedback loop nugget from a small business app for photographers.
The founder got up on stage and was going on about how he was struggling to find traction with his product. He was the designer and the product manager. So he wore a couple of hats which would have been quite emotional when he wasn’t seeing the product grow from how much effort he had put in.
So he went on to mentioning he built a Facebook Group where he’d get his second best customers to leave feedback on the product so he could improve.
He then added a bunch of his best customers a little later to educate his second best customers on coming up to being his best customers.
He doubled his product value in a much smaller timeframe than he normally would have.
