The Future

Why TTD is leading?1. We care 2. Our employees matter3. We align our interests

with our clients

Help agencies level up their business model

Ad Agencies matterWe are not a disruptor. We enable.

We are SaaS like, pointed at data, advertising and marketing• We are not a media company

• We have 95%+ client retention, and a unique and more profitable business model than SaaS

• Price discovery is foundational to healthy markets

• Data driven is better than guessing

• Programmatic will eventually power all 600 Billion (soon to be 1 Trillion)

• Buy side is forever in a power position

• Decisioning is where the money is

• Sell-side fragments

• Sum of tech take rate is 25-30% (sell side and exchange side is too high right now)

• Buy-side aggregates around 3 to 10 players

• At least one will be independent

• To be one of those standing at steady state:

• Global

• Omni channel (mobile and TV most important)

• Each will have a unique data advantage

The basic tenets of our strategy 10 years ago

We are not competing with Google & Facebook. Media is.

Objectivity matters more as time goes on
