How should modern software founders approach the tension between serving niche developers and broad markets?

I look to the classic four-point plan: start by building an uncompromising, premium product for a passionate, highly discerning niche of early adopters. Perfect the user experience for that core cohort until they become evangelical advocates. Once you achieve undeniable dominance within that vertical, systematically broaden your distribution, expand platform capabilities, and transition toward mass-market enterprise adoption without compromising your core design standards.
