Where Eric grows international markets
Castelein AV.
Where the system earned its scars.

Why this page exists
Live events don't forgive missing systems.
When the show starts at eight, "we'll improvise" is not a plan. Running an event production company means documented processes, communication on rails, and follow-through that doesn't depend on memory — because the cost of a dropped ball is public and immediate.
Many of the ideas behind the Business Growth System were refined here first, inside a real operational business with real deadlines. It's one thing to recommend systems. It's another to bet our own show nights on them.
