Why do you advise against building generalized vertical SaaS platforms as a first step?

Building generic horizontal SaaS is an unforgiving trap for solo founders because you immediately face high customer acquisition costs, relentless feature requests, and intense commoditization. By offering a bespoke, high-touch agent implementation, you command premium service fees while gathering deep domain intelligence. Once you implement identical agent workflows for ten clients in the same niche, you can productize the underlying architecture into software.
