What happens when customers stop searching—and start asking? That shift is already underway. Instead of typing keywords into Google, users are turning to ChatGPT, Claude, and other AI systems to get answers, recommendations, and even complete transactions. The result: fewer clicks, fewer visits to websites, and a new layer of decision-making that most companies don’t control. Jochen Madler, co-founder and CEO of SiteFire, is building for that future. After starting in academia with a focus on statistics and reinforcement learning, Jochen left his PhD to tackle a growing problem: brands are losing visibility inside AI systems, and they don’t know why. The Moment Everything Broke A turning point came when Google introduced AI-generated summaries in search results. Some companies saw impressions stay stable—but clicks dropped sharply. Users got their answers directly from Google, without visiting the source. In one case, this shift hit revenue hard enough to trigger a major market reaction. That exposed a simple truth: Traffic is no longer guaranteed, even if demand exists. If AI systems answer the question, your website might never get visited. Search Has Changed—But Most Teams Haven’t Traditional SEO was built around keywords. Users typed short queries. Companies optimized pages to rank for those terms. Traffic followed. AI breaks that model. Instead of 3–5 word queries, users now write full prompts. AI systems expand those prompts into multiple searches, evaluate results, and generate a single answer. That means: * Your brand might be mentioned without a click * Your competitors might be summarized alongside you * Or you might not appear at all The unit of competition is no longer a webpage. It’s inclusion in the answer. From Customer Experience to Agent Experience Most companies still optimize for human users. Jochen argues that’s the wrong focus. AI agents are becoming the primary interface. They read content, compare options, and increasingly take action—whether that’s recommending a product or completing a purchase. This creates a new layer: agent experience. It’s not about how your website looks. It’s about: * Whether AI systems can understand your content * Whether they trust your information * Whether they can interact with your product or API In some cases, this is already happening. AI systems can discover tools, authenticate, and use services without a human clicking anything. Content Is Getting Cheaper—But Harder to Get Right AI has driven the cost of content creation close to zero. Anyone can generate blog posts, landing pages, or documentation at scale. That creates a new problem: volume is no longer an advantage. What matters now is precision. The winning content is: * Structured for AI systems, not just humans * Aligned with how models retrieve and rank information * Positioned in the right places across the web In some cases, that’s your own website. In others, it’s platforms like Reddit, YouTube, or third-party publications. There is no single playbook. It depends on the query, the model, and the context. Why SEO Isn’t Enough Anymore Many teams assume this shift is just “SEO 2.0.” Jochen disagrees. SEO focused on ranking pages. AI search focuses on assembling answers. That changes how visibility works: * Ranking #1 no longer guarantees traffic * Being cited matters more than being clicked * Brand presence inside the answer becomes the goal This is where new categories like “Generative Engine Optimization” are emerging—but even that framing may be too narrow. The bigger shift is toward influencing how AI systems think, not just what they rank. The Next Step: Agents That Act Today, AI systems mostly inform decisions. Soon, they will execute them. That includes: * Booking tickets * Purchasing products * Integrating APIs * Managing workflows In one early example, an AI system discovered a company’s API, authenticated, and started using it—without any human involvement. That’s a preview of what’s coming. When agents take over the full journey, the “funnel” changes: * Discovery happens inside AI * Evaluation happens inside AI * Transactions happen through AI If your product isn’t part of that flow, you don’t exist. What This Means for Founders This shift is still early. Most companies see less than 10% of their traffic coming from AI systems today. But it’s growing fast. That creates a window. Founders who move early can: * Capture visibility before the space gets crowded * Build systems optimized for AI from the start * Lock in distribution as agents become more dominant Those who wait risk losing their primary growth channel without realizing it. The Bottom Line Search isn’t disappearing. It’s being abstracted. Instead of users navigating the web, AI systems are doing it for them. That changes who controls attention—and how companies earn it. Jochen is building for that world. Because when AI decides what gets seen, recommended, and bought… marketing doesn’t go away. It just moves behind the interface. 👂🎧 Watch, listen, and follow on your favorite platform: https://tr.ee/S2ayrbx_fL 🙏 Join the conversation on your favorite social network: https://linktr.ee/theignitepodcast Chapters:00:01 Introduction & SiteFire Overview00:28 Jochen’s Background in Statistics & Energy Systems01:18 Founding SiteFire & Early YC Journey02:14 Moving to San Francisco & Ecosystem Exposure02:50 YC Experience & Key Takeaways04:00 Advice for Founders Applying to YC05:25 From Reinforcement Learning to AI Marketing06:20 Identifying the AI Search Opportunity07:35 Google AI Overviews & Traffic Disruption08:30 Rise of AI as the New Interface09:17 Why AI Search Isn’t SEO 2.010:53 Rational Search vs Human Behavior12:29 Marketing as a Math Problem14:01 AI Search vs Traditional Channels15:26 Websites Becoming Agent-Focused16:33 Human Traffic vs Agent Traffic Trends17:46 Adoption Gap & Real-World Usage19:14 Long-Term Evolution of Search & AI21:01 GEO vs AEO Debate21:43 Agent Experience as the New Frontier22:02 What Winning in AI Search Means23:12 Distribution Risk if Google Disappears24:10 OpenAI’s Role in Search Distribution24:41 GEO vs SEO Debate Revisited25:11 Markdown, Content Structure & AI Readability25:58 SiteFire Product: From Monitoring to Execution28:47 How AI Models Rank & Retrieve Content31:00 Early Product Traction & Breakthrough Results32:12 Content Strategy: Domain vs Platforms34:00 Product vs Services Approach34:58 Hardest Technical Challenges36:31 Misconceptions About AI Marketing38:25 Content Commoditization & Future of SEO39:17 Competition & Incumbent Risk42:27 Future of AI Agents Replacing Search43:27 AI Agents Executing Transactions44:56 Agent Reviews & API Ecosystems45:47 Where Value Accrues in AI Stack48:15 Vision for SiteFire & Agent Funnels51:10 Rapid Fire: Startup Lessons & Beliefs Transcript Brian Bell (00:00:57): Hey everyone welcome back to the ignite podcast today we’re thrilled to have Johan Madler on the mic he is the co-founder and CEO of Sightfire it’s a YC winter 26 company and a team ignite portfolio company building the marketing infrastructure for the agentic web helping brands show up inside AI systems like chat GPT I think I’ve heard of those guys a Gemini and Claude thanks for coming on Jochen Madler (00:01:18): Yeah, thanks for having me. Brian Bell (00:01:19): Well, I’d love to start with your background. What’s your origin story? Jochen Madler (00:01:22): So I grew up in Germany, Munich, Germany, and my background is really like technical, so statistics. I fiddled around a little in energy markets and like statistics for energy market simulation, did reinforcement learning optimization for energy grids. But then, yeah, I did a PhD in the same thing and then dropped the PhD to found Sidefire. So me and my co-founder, we met like seven years ago. We know each other since a long time, had all like hackathons competitions together. And then one day he came around and made me reconsider. Brian Bell (00:01:52): That’s amazing. So he kind of pulled you out and said, hey, let’s do a startup. Jochen Madler (00:01:56): Yeah, pretty much. Brian Bell (00:01:58): That’s great. It’s always good to have those kind of friends that pull you out of your comfort zone. And then how did the app applying to YC come about? Jochen Madler (00:02:07): So we started building Sidefire end of 2025. And back then in Germany, it was really about this AI monitoring space, really fiddled around with like GPT-5 came out. Everyone was thought of like, this is not the end of like anything or everything. software engineering all of it didn’t happen but then we like really got into this AI search Google AI model launch Google overviews launch and so we really started building this monitoring infrastructure and quickly sold it to like pretty large companies in Germany like BMW Deutsche Bank and Allianz and then we got into YC so everything actually happened pretty quickly we started end of 25 in like November building and in December January we were already in San Francisco Brian Bell (00:02:46): What was it like to come live in the U.S., live in San Francisco, you know, there for three or four months during the entire batch? Jochen Madler (00:02:52): Yes, exactly. Yeah, San Francisco, actually Dogpad is pretty close by. Yeah, it’s amazing. I mean, I’ve been there before in my time at Stanford. So I know the area. And of course, it’s like, yeah, if you’re building something like this, you at least want to have the ecosystem. And YC is, in my opinion, the perfect thing, because, of course, the agentic web and everything like these systems are being built there. And so, yeah, we now have actually like are in good contact with all of the big firms. And yeah, also, the ecosystem is just like really amazing. Brian Bell (00:03:20): What was that whole experience like for you? Jochen Madler (00:03:21): So I thin
