Mar 13, 2026
They unpack founder trauma, including a $350k scam and life after selling a company. They tear into Connected TV’s pricing, 12-hour ad caches, and how that enables dark-pool arbitrage.

Episode notes
CTV Cache Windows Create Arbitrage Dark Pools
- Both hosts argue CTV is full of opaque inventory and price asymmetry, causing premium publishers to avoid biddable CTV and prefer guarantees.
- Long ad-cache windows (e.g., 12 hours) create dark-pool arbitrage and multiple simultaneous price points for identical inventory.
Meta Captures DTC Value Through Second Mover Effect
- Facebook's ad algorithms create second-mover advantage: early DTC advertisers train the platform and effectively subsidize competitors.
- Gareth and Adam say marketers pour budget into Meta and the platform captures marginal value, leaving brands with the data but little ownership.
Inventory Signals Can Undercut DSP ID Premiums
- Bidding on inventory signals instead of DSP audience IDs can cut CPMs dramatically, shown by a Denmark example where CPM fell from $3 to $0.90.
- The hosts argue platform ID clustering drives a small set of high-value auctions and inflates prices.
