Castro founder admits customer support failed as a differentiator

Short summary

Castro's founder reflects on why personal, thoughtful customer support failed as a product differentiator. He categorizes six types of support emails—pricing complaints, bug reports, edge cases—and explains why honest responses frustrated rather than built loyalty. The lesson: support that satisfies both parties occurs in <1% of emails; over-serving demanding users drains resources without proportional revenue.

• •Personal support doesn't build loyalty; most responses frustrate customers more than satisfy them
• •Six support email categories each create mismatched expectations between user and founder
• •Focus resources on the rare case where support actually resolves problems; reject the rest
