One AI opportunity I don't see enough developers talking about. AI infrastructure for small and mid-sized companies. Most businesses don't need to train their own foundation model. They need someone to connect AI to the systems they already use. Their CRM. Support inbox. Internal documentation. Databases. Analytics. Project management tools. The difficult part is rarely the API call. It's authentication, data access, workflow design, reliability, monitoring and making sure the system doesn't create more work than it removes. A developer who can take a messy business process and turn it into a reliable AI workflow can create real value. Examples like Automated support triage. Internal knowledge search. Sales research. Invoice and document processing. Engineering incident analysis. Operations reporting. This is also a practical way to enter AI without competing with foundation-model companies. You don't need to build the next frontier model. You can build the software that makes existing models useful.
