Tim and Chris Vanderhook on Viant’s Lattice Brain: How Autonomous Advertising Beats Human Traders

Tim and Chris Vanderhook on Viant’s Lattice Brain: How Autonomous Advertising Beats Human Traders

From CES, Ari Paparo talks with Co-founder and CEO Tim Vanderhook and Co-founder and COO Chris Vanderhook of Viant about what automation looks like in a DSP workflow, using Viant’s Lattice Brain and Outcomes as the framing. They cover how goal-based optimization is set up (CPA/ROAS), what they observed in tests comparing automated and human-managed campaigns, and why “decision latency” is a recurring issue in day-to-day programmatic execution. 


Takeaways

  • They describe Outcomes as a goal-based workflow where an advertiser provides key inputs and the system handles ongoing optimization decisions.
  • The guests share results from internal tests comparing automated vs human-managed campaigns, and discuss what signals they looked at beyond the final CPA.
  • A main theme is “decision latency”; humans operate on meeting and approval cycles, while automated systems can adjust continuously.
  • They distinguish between transparency and control: visibility into where spending goes, but limited ability to override optimization choices.
  • They expect a hybrid approach, with some budgets remaining hands-on and others shifting toward more automation.
