@kenneths If it's VC-funded you can even copy shamelessly - again, don't infringe on copyright, so don't 1:1 copy as that's illegal. So don't copy names, IP, exact 1:1 screens, etc. But you can copy
THE WAY IT BRINGS VALUE TO THE USER
If you can do it while making it yours - you actually "deserve" it better, since you're doing better than the funded competitors. And if you're not doing better but you're still getting a piece of the pie... good for you! They toiled so hard to create the industry and carve a path - and you're piggybacking them!
even if you pick a subset
I got copied blatantly with my first company - multiple times. Didn't get mad - just looked and said "hey, they got 80% of our upside, with 20% of downside, since we carved the path. Let's do something like that next time for our next company!"
