Most companies think Finance reports performance.

The best companies know Finance should drive it.

In this episode of the Lean Focus Podcast, Damon Baker sits down with Mark Dyas, CFO of Lighteum Medical, to discuss what happens when a Lean-thinking CFO stops acting like a scorekeeper and starts operating as the connective tissue of the business.

Mark has led transformation across public companies, privately held organizations, and private equity-backed environments, and he’s seen the same pattern repeat itself: strong historical performance masking operational risk, leadership teams reacting to results instead of managing the drivers, and Finance focused on reporting the news instead of changing the outcome.

In this conversation, Mark shares how he:

• Identifies operational problems before they show up in EBITDA or cash flow,
• Turns Finance from a reporting function into a value-creation engine,
• Uses data and storytelling to challenge assumptions without creating blame,
• Focuses organizations on the critical few drivers that actually move enterprise value,
• Builds cross-functional alignment through processes like Sales, Inventory, and Operations Planning, capital discipline, and performance management,
• Balances financial discipline with culture, trust, and long-term organizational health,
• Navigates the tension between traditional GAAP accounting and the operational behaviors required for Lean performance.

This episode is a masterclass for CEOs, CFOs, and private equity leaders who want Finance to do more than measure the business — they want it to help run it.

Because the most effective Finance leaders don’t just report the story.

They help rewrite it.
