1 The Certainty Premium: What’s Driving the Tech Sector Divergence? | Jeff Keller
2 (00:00) **Opening Hook & Host Introduction** - Max Wheaty introduces the episode’s core tension: long-term uncertainty is so high that anything with short-term certainty trades at a huge premium
3 (00:28) **Guest Background: Jeff Keller of Cape Light Partners** - Keller explains his operational background at Salesforce and MongoDB, which orients him toward longer-term thematic investing
4 (01:13) **The Q3 Tech Sector Divergence** - Since Q3 started, software is up 20%, hardware is flat, and semiconductors are down 7.5%
5 (03:14) **Software’s Bounce: Technical or Fundamental?** - The rally in software raises the question: is the market saying software isn’t at risk from AI disruption, or is this just degrossing from hedge funds unwinding paired AI longs/software shorts?
6 (04:33) **The Certainty Premium in Cyber and Infrastructure** - Anything usage-based with short-term visibility is trading at huge multiples (25-30x revenue for large companies)
7 (06:52) **Infrastructure Examples: MongoDB and Usage-Based Models** - Keller uses MongoDB (where he worked) as an example: AI drives software proliferation, and every app needs a database underneath

Max Wiethe sits down with Capelight Partners founder Jeff Keller to dissect the massive Q3 technology sector divergence and the rapidly shifting landscape of AI investments. Keller breaks down why the market is rewarding near-term certainty in the tech sector and why he doesn’t like the "blow-off top" comparison between AI and the ARK implosion of 2021. He also gives his outlook for usage-based software vs. application software and explains the east coast vs west coast divide in assessing hyperscaler capex.
