Revenue Up 2x, EBITDA Up 5x: The Operating Model Behind It with Andrew McBarnett

Jul 30, 2026

Everyone wants AI to fix their messy data. Andrew McBarnett will tell you straight: it won't.

In fact, it'll just help you reach the wrong conclusion faster.

Andrew is Group Financial Director at Lucid Group, a PE-backed medical communications agency. He joined in 2020 for what was meant to be a four month contract. Six years later, he's still there, and the numbers tell the story: EBITDA up from £3.6m to £18.1m, revenue more than doubled, legal entities cut from 25 to 15, and a finance team that's shrunk in headcount while transaction volume has nearly doubled.

In this conversation, Andrew explains how he diagnosed a business that looked successful on the surface but was being held back by its operating model.

Here's what we get into:

  • Why numbers don't explain your business, they just reveal where the pain is
  • Andrew’s five pillars of an operating model that can actually scale
  • Why "businesses don't fail to grow, they fail to absorb their growth"
  • How Lucid built single sources of truth across accounting, project delivery, and expenses
  • Why AI was never the goal, it was the reward for doing the foundational work properly
  • What changing the culture of a team actually takes (it’s harder than the tech, according to Andrew)

Plus, Andrew shares the real reason finance teams get sidelined in the business, and how to fix it.
