DON'T HAVE A BIGGEST CUSTOMER

Summary from the TLDR Founders newsletter

When a large customer outgrows your SaaS product, wish them well or accommodate them if it benefits your entire customer base. However, having a "largest customer" is actually a company's biggest weakness. If losing a single customer is detrimental, you're no longer making your own product but rather custom software for big clients. The solution is to cap prices so no one pays significantly more than others. Aim for a customer base that looks like "even static," where each one's financial impact is indistinguishable. That way, if any random customer leaves, you won't feel it or fear it.
