I have quit from more than 10 companies (i'm old), and I'd say that 100% of the time the reason was shitty managers.
But "A raise in pay" would be the best solution to convince to me stay.
I'm not that old, worked with 14 companies, every manager was on the shit scale. Even when I saved a smaller companys biggest client, by rewriting critical part as a new hire when no one else could get it to satisfy new requirements, the manager told me I should not expect more money, since I didn't finish Uni.
