Modern agencies aren’t losing margin in pricing - they’re losing it in delivery.
Scope creep. Rework. Poor forecasting. Disconnected pipeline and delivery. By the time pricing is discussed, margin is already gone. OPERATE ‘26 brings together leaders from scaling agencies responsible for delivery, resourcing, and profitability, the people fixing where margin leaks.
WHY NOW
Delivery complexity is increasing.
AI is accelerating client expectations.
Sales is moving faster than operations can support.
)
WHAT YOU’LL LEARN
Predict delivery and protect margin before it’s lost
Align teams and improve utilization, visibility, and planning
Learn what’s working at scale — and how AI is actually being applied in delivery
)
WHO YOU’LL MEET
Leaders scaling delivery across 50+ employee size agencies
Operators accountable for utilization, forecasting, and margin
Decision-makers connecting sales, resourcing, and execution
Peers navigating growth, complexity, and rising client expectations
