# Free Discovery Call - 30 Minutes with Jim Nittterauer

> Most mid-size companies are running real AI and cyber risk without anyone in the building who owns it. Not because leadership doesn't care - but because hiring a full-time CISO is a $300K+ commitment, and the problem doesn't wait for the hire. This call is 30 minutes. No pitch deck, no pressure. We'll talk about where your business is, what's actually exposed, and whether there's a fit. If there isn't, I'll tell you that too. Book the call. The conversation is free. The risk of not having it isn't.
