What if the culture problem you keep chasing is actually a signals problem?

Nathalie Brochstein has spent over a decade inside Fortune 100 companies untangling the mess that happens when leaders say one thing and teams hear something completely different. Now, as the founder of Karibu, she’s bringing those lessons to startups that are scaling fast and watching their alignment fall apart in real time.

In this episode, Nathalie joins Katie and Maria to lay out what culture actually is: how effectively messages move through your organization. They dig into the onboarding mistakes that kill retention before day 30, the green dashboards that mask total system failure, and why the popular advice to “hire smart people and get out of the way” quietly drives your best hires toward the door. Nathalie also walks through her organizational DNA framework, makes the case for keeping a human in the loop on AI, and offers a simple test any founder can run today to find out whether their team is actually aligned.

Key topics: culture as signal flow, scaling communication, onboarding and time to competency, the forgetting curve, false-positive metrics, operational documentation, AI in operations, human-in-the-loop, inclusion as operational infrastructure, test-driven operations
