Direct answer
If you have an AI idea but no CTO, the first move is not hiring a large team. Define the user workflow, data source, AI boundary, quality check, MVP scope, and build options before committing to engineering spend.
The first CTO-level questions
What repeated decision gets easier? What data is available? Where must the result be deterministic? What can be manual in version one? What proves someone will pay? Those answers matter more than the model choice.
