Now That I Know. The Podcast

Hosted by Mindy Corbett and Cale Corbett. No corporate polish. Just a raw look at the blind spots impacting your success and sanity. We put our own faceplants on the table to talk about jobs, spouses, customers, and ourselves. Fixing expensive corporate disasters and the workflows bleeding cash. Nurturing marriage and ambition in adjacent home offices. Facing the brutal truths and data the market is screaming at us. And building two brand-new businesses at the same time.
