Shahin Farshchi, partner at Lux Capital, joins us to talk about investing in the next generation of neural interfaces. Lux is currently investing out of a $1.5B fund, and its portfolio includes Anduril, Hugging Face, Zoox, and CTRL-Labs.

Shahin likes to say neural interfaces have been “five years away” for 20 years. But something has changed. Tune in to find out what.

In this episode, we discuss:

• How Shahin evaluates brain-computer interface companies
• His thesis behind investing in Flourish Labs and Unconventional
• Voice as the next major interface
• How he spots the next tech wave before it arrives

Naren Tallapragada (co-founder of Tessel) joins to talk about the industry of modeling biology. While the field races to build virtual cell models, his team builds virtual tissue models, betting that predicting what an organ actually does matters more than predicting what genes a cell expresses. The goal: not just whether a drug works, but who it works for.

In this episode, we discuss:

• Why 90% of drugs fail in clinical trials, and why neuro and Alzheimer's failure rates are even worse
• The multi-scale modeling problem: molecules, genes, cells, tissues, organs, and why picking the right level of resolution matters more than picking the "best" one
• The electron-and-lightbulb argument for why virtual cell models may be a beautiful solution to the wrong problem
• Organoids vs. animal models: where human cell models beat animals, and where both fail (like modeling behavior in mental health)
• Why Naren thinks defensibility in AI-driven biology comes from proprietary multi-organ data, not model architecture
• The case for precision medicine, and why it's been such a brutal business model to actually execute on

Mariëlle van Kooten (CEO and co-founder of Powerhouse Biology) joins to make the case that mitochondria are the best place to start engineering the human body. Her team builds virtual mitochondria models to predict how a fix will behave before it ever touches a patient. Marielle is passionate about treating disease and human enhancement.

In this episode, we discuss:

• Why mitochondria might be the most tractable place to start engineering human biology
• The difference between building a virtual mitochondria model and the industry-wide race to build a virtual cell
• Why a protein fix for one disease (say, Parkinson's-linked muscle weakness) could work across totally unrelated tissues
• The difference between Science vs. Engineering: why she left academia
• The case for human enhancement: longevity, resilience, and why the ethics conversation is stalled

Professor Alysson R. Muotri (geneticist and developmental biologist at UC San Diego) joins for a far out conversation about sending brain organoids to the International Space Station and what they're teaching us about aging, neurological disease, and a new kind of AI. One month in orbit ages an organoid the equivalent of 10 years on Earth, and Alysson's lab has already used that compressed timeline to unlock an FDA-approved clinical trial for a drug developed in space.

In this episode, we discuss:

• Why space accelerates brain aging
• The surprising role of "junk DNA" and endogenous retroviruses in neuroinflammation and neurodegeneration
• Why HIV antiretroviral drugs may be the key to treating neurological conditions
• What the decommissioning of the ISS and the rise of commercial space stations mean for biomedical research
• How brain organoids learn, remember, and inspire a new generation of AI algorithms beyond transformers
• The bioethics frontier: when do organoids become conscious and how would we even know?

Jonathan Sporn (CEO + Founder of Gilgamesh Pharma) joins for a deep dive into next-gen psychedelic medicines, why duration matters for real-world clinical use, and what it takes to build these therapies the way large pharma would—culminating in a partnership with AbbVie worth up to $1.2B.

In this episode, we discuss:
• Why Gilgamesh is building psychedelic medicines the way large pharma would
• The thesis behind short-acting psychedelics and why long-duration trips are impractical for real-world psychiatry
• How Gilgamesh designs molecules backwards from clinical needs
• Effective approaches to the challenges of trial designs for psychedelics
• What AbbVie’s deal and Spravato’s trajectory mean for psychedelics
• How psychedelic medicines could reshape mental health

Greg speaks with three leaders in mental health philanthropy: Alyson Nieman from Mindful Philanthropy, Sabrina Gracias from Ortus Foundation, and Christena Huntsman Durham from Huntsman Mental Health Foundation, each offering a distinct perspective on how funding decisions get made and where the biggest gaps remain.

In this episode we discuss:

• Trends in mental health philanthropy, and the 10-year challenge: how the field moves from roughly $2B to $35B in annual funding.
• Funding the clinic of the future: a $150M philanthropic gift behind the Huntsman Mental Health Institute’s crisis care center
• Youth mental health: how the Ortus Foundation is addressing regional gaps in the US Intermountain West

Greg interviews Rick Perry, the former Governor of Texas and former U.S. Secretary of Energy and leading advocate for ibogaine, live at the Real Summit.

In this episode, we discuss:

• How a former Texas governor moved from strict opposition to drugs to becoming a leading advocate for ibogaine after firsthand experience and veteran outcomes.
• Ibogaine’s impact on PTSD, opioid addiction, and traumatic brain injury, including Stanford-linked brain imaging data showing functional and structural improvement.
• How veterans are the proving ground that enabled Texas to commit $50M in public funding for ibogaine clinical trials.
• Why ibogaine requires intensive medical supervision and why rigorous trials are essential for legitimacy and scale.
• A vision where ibogaine reshapes addiction treatment, veteran care, and eventually criminal justice and homelessness policy.

Matias interviews James (Jim) Gorman MD PhD from the Wyss Institute. Jim is Principal Investigator on the Wyss Institute Brain Targeting Program (BTP). Jim leads a team developing new approaches to transport drugs through the blood brain barrier (BBB) into the CNS.

In this episode, we discuss:

• Why the BBB blocks most modern drugs from entering the brain, creating the biggest bottleneck in neuro
• How brain shuttles hijack natural transport pathways like the transferrin receptor to move drugs across the BBB
• How new modalities that reach the brain can potentially treat diseases like Alzheimer’s, Parkinson’s, ALS, and lysosomal disorders
• Why delivery route of shuttles enable IV or subcutaneous dosing instead of invasive intrathecal injections
• How early data shows that shuttle-enabled antibodies clear amyloid faster, at lower doses, and with fewer side effects
• How the field is accelerating through a pre-competitive consortium model that lets multiple companies share shuttle platforms
