When I first started we would be doing 1-off feature requests "because the client would _really_ like it". Everything was justified because money and because "we cant afford to lose that customer!" in our SaaS product.

I saw our main product being neglected because we'd invest so much time in these 1 off features only 1 client would use. All we would ever do would be client features, I was going crazy. It took a lot of talking, and still to this day I have to get him to think in terms of the product instead of the individual client.

Now we make more money, have more clients, and better our product for everyone which in turn gets more clients to get more money.
