In this episode of Next in Media, I sit down with Philip Inghelbrecht, Co-Founder and CEO of Tatari, to unpack why one of the most innovative companies in TV advertising has built its entire thesis on a contrarian idea: that programmatic CTV is the wrong tool for most of the television market. Philip walks through how Tatari operates as a full infrastructure holding company, combining a demand-side platform, a supply-side solution called Upstream, and a privacy and identity layer called Vault. From day one, Tatari has argued that unlike display advertising, connected TV is dominated by a small number of premium publishers, and that automating around them rather than through open exchanges is the smarter path forward.

Philip breaks down the $30 billion US CTV market, explaining how roughly half flows through programmatic channels and how up to half of that programmatic slice is fraud or low-quality inventory. The premium inventory that actually drives results, including sports, tentpole events, and top-tier streaming placements, lives almost entirely outside programmatic pipes and has historically required massive budgets and manual negotiation to access. That is exactly the gap Upstream was designed to close. By building custom, direct integrations with the five biggest TV publishers, including Disney, Warner Bros., NBCUniversal, and Paramount, Tatari has automated that direct buying process end to end, giving a much broader range of brands access to premium TV inventory without sacrificing pricing control, brand safety, or transparency.

📡 Programmatic CTV Is Built on the Wrong Foundation: Philip explains why the SSP/DSP model designed for display advertising is a poor fit for connected TV, where 90% of streaming impressions come from the same top 10 publishers and the most valuable inventory never appears in an open exchange.

💰 The $30 Billion Reality Check: Of the roughly $30 billion US CTV market, about $15 billion flows through programmatic. Philip reveals that up to half of that programmatic pool is fraud or low-quality supply, meaning only $7 to $8 billion represents genuinely premium inventory.

🚀 Upstream Brings Automation to Direct TV Deals: Tatari spent nearly two years building one-to-one tech integrations with Disney, Warner Bros., NBCUniversal, and Paramount, enabling fully automated direct buys that preserve the brand safety and pricing control of traditional direct sales while eliminating manual overhead.

📺 Premium TV Is Now Within Reach for More Brands: Upstream shifts TV advertising from a big-budget brand privilege to something accessible to a much broader set of advertisers. Brands that never could have accessed premium placements now have a real path in, and early publisher partners have already seen doubled transaction volume during the test period.

🤖 AI in TV Advertising Has Promise But Real Limits: Philip is measured about AI's near-term impact on TV. He sees immediate wins in automating creative pre-approval and longer-term potential in data-driven yield optimization for publishers, but pushes back on the idea that AI will quickly transform the TV creative production process.
