Back in '96 I was in a startup company in the Boston area. We had a B2B app that we customized per customer. It worked over dial-up. We didn't foresee affordable internet connections coming. When it did we couldn't rewrite critical subsystems quickly enough. Because our product was customized per customer - not just look-and-feel, we coded their business rules into it - we had problems scaling. Further, our design didn't lend itself to rapid development. First our sales team left. Then developers started to leave. Within a couple of years after I left, the company folded. Many good experiences had in that company. Many lessons learned.
