In this episode of How I Built This Lab, Guy Raz interviews Immunai CEO and co-founder Noam Solomon about leveraging artificial intelligence, single-cell genomics, and advanced mathematics to map the human immune system and transform drug discovery.

speaking balance: gold is Guy, purple is the guest (3 minute bins)
Noam directly reframes Guy's autonomous vehicle comparison, emphasizing that unlike autonomous driving where human drivers serve as a benchmark, drug discovery has no successful human baseline since 90% of drugs fail.
Hardest push from Guy ▶ 30:58 Guy presses on lingering risk and uncertaintyGuy challenges Noam on why there is still so much talk of high risk and uncertainty given the company is four years in, highly funded, and demonstrating clear progress.
Biggest teaching moment ▶ 10:54 The mouse model fallacy in oncologyNoam educates Guy on the fundamental flaw in modern drug development by quoting a mentor: 'we can cure every type of cancer in mice,' illustrating why animal models fail to translate to human immune responses.
Guy holds their own ▶ 27:25 Guy cites AlphaGo's Move 37Guy displays deep background knowledge of Immunai's published thought leadership, citing co-founder Luis's essay on AlphaGo's Move 37 to query whether AI can discover non-intuitive oncology targets.
the scores for every segment, with the reasoning behind each
| Chapter | Topic | Guy as informed peer | Guest teaching | Guest disagreement | Guy pushing back | Why |
|---|---|---|---|---|---|---|
| Origins: From Mathematics to Immunotherapy | 3 | 2 | 0 | 0 | Guy asks open-ended biographical questions about Noam's transition from academic math postdocs at Harvard and MIT to founding a biotech company. Noam explains how his co-founder's grandfather's adverse reaction to cancer immunotherapy inspired him to apply data science to medicine. | |
| Building the 'Google Maps' of Immunology | 3 | 4 | 0 | 0 | Guy asks Noam to explain the 'Google Maps' metaphor for the immune system. Noam educates the host on single-cell technologies that measure 20,000 genes per cell and generate a terabyte of data per patient sample. | |
| Technological Convergence and Personalized Medicine | 3 | 4 | 1 | 0 | Guy hypothesizes that because every human immune system is unique, universal mapping could immediately personalize treatment. Noam gently refines this by comparing immune systems to eye colors—individual but falling into distinct, clusterable categories. | |
| Drug Development Inefficiencies and Animal Models | 4 | 5 | 0 | 1 | Guy asks about immunotherapy development bottlenecks, and Noam outlines the $2.6B cost and 90% failure rate. Noam teaches Guy about the critical translational gap between animal models and human immunology with the insight that science can cure cancer in mice but fails in humans. | |
| Business Model, Revenue, and Industry Collaboration | 4 | 3 | 0 | 1 | Guy probes the business model, noting $300 million raised might not be enough for massive scientific R&D, and asks about competition. Noam explains their fee-for-service revenue model with pharma partners and welcomes industry competition. | |
| Data Ingestion, MICA Database, and Trial Optimization | 3 | 4 | 0 | 0 | Guy asks practical questions about how physical data collection works across global medical partners. Noam details their MICA database covering over 100,000 patients and 500 disease indications across blood and tissue samples. | |
| Responders vs. Non-Responders and Cancer Simulations | 3 | 5 | 0 | 1 | Guy asks if mapping could make all cancers treatable in 50 years. Noam gives an in-depth biological breakdown of how subtle gene variations distinguish drug responders from non-responders and why computer simulations are needed to model cancer escape mechanisms. | |
| Multidisciplinary Teams Bridging Math and Biology | 3 | 3 | 0 | 0 | Guy highlights the synthesis between computational power and biology. Noam describes building cross-disciplinary teams where mathematicians study biology and immunologists learn machine learning. | |
| Embracing Curiosity: 'When Not Knowing Is a Methodology' | 5 | 4 | 0 | 0 | Guy demonstrates preparation by citing Noam's essay on curiosity and co-founder Luis's article about AlphaGo's Move 37. Noam elaborates that immune mapping is far higher-dimensional than Go, requiring AI because human intuition cannot process 20,000 variables across thousands of cells. | |
| Autonomous Vehicles Analogy vs. Drug Discovery | 4 | 5 | 1 | 2 | Guy draws an analogy between data loops in autonomous vehicles and drug discovery, then pushes on why high uncertainty remains after four years of progress. Noam dismantles the AV analogy by pointing out AVs have human driving benchmarks, whereas drug discovery lacks any reliable human baseline. |
