>Actually, your replacement may need several months just to get to know the way you did things, where's what in the code, what's the app doing etc. Specially in a vertical, which may get very rich in features. The last one like that took me years to get to most of the stuff, and there are still areas in it which I never visited, let alone touched. And working with a partner may get you not just ideas on how to improve the app and keep up with the times, but may actually bring more customers. So I'd take Tamar's 3 years seriously.
The key is the "partner" which is quite different from an "employee."
