Understand the business and the stack.
You have engineers. What you do not have is the senior voice in the room who has shipped this before and can tell you which path is a trap before you walk down it.
Hiring a full-time CTO at this stage is heavy, slow, and expensive. Flying blind on the big calls is more expensive, just later. This is senior technical leadership on a retainer: the judgment without the equity and the payroll.
Understand the business and the stack.
Architecture, roadmap, and hard calls.
Retainer support, not a one-off report.

A set number of days a week or month, scoped to your stage. It flexes as you grow.
That is a conversation worth having.
