I'd say that for my own, it was treating it like a service business a few days after launch.
We had a customer that kept on making requests and we kept on giving them, which cost us a lot of time.
How about you?
When we built Shelfster in 2013, we were so in love with our idea that we completely underestimated the competition. We thought we were more innovative. We were confident that we could build something much better.
The biggest mistake was that what we thought would be better wasn't necessarily beneficial to the users. The lesson we've learned: a feature that your users will appreciate is not always the one you've invested the more resources in or the one you like best. It's the one that solves their problems.
