Episode Summary

In a highly anticipated episode of the All-In Podcast, host David Friedberg conducts an exclusive interview with Billy Evans, entrepreneur and husband of former Theranos CEO Elizabeth Holmes. Evans provides an inside look at their relationship, detailing how they first met in San Francisco just before her indictment by the DOJ (Department of Justice). He pushes back against the media narratives cemented by journalist John Carreyrou, his book Bad Blood, and the television series The Dropout, arguing that Holmes strictly adhered to a judicial gag order, leaving her unable to defend herself publicly. Evans discusses the trial dynamics, highlighting that while she was acquitted of patient fraud regarding millions of tests, she was convicted of financial fraud involving prominent investors like Rupert Murdoch, the Walton Family, and the DeVos family. Holmes is currently serving a 135-month sentence at Bryan Federal Prison Camp, which is located in College Station, Texas, and managed by the Bureau of Prisons. However, Evans notes that the First Step Act, signed into law by President Trump, along with a recent sentence reduction, could allow her to transition to a halfway house sooner than expected. To counter the established media narrative and show her true character, the couple participated in an upcoming documentary directed by Nathan Fielder. Professionally, Evans clarifies rumors that he is building a Theranos 2.0. Instead, he is leveraging his background at Luminar, a company that built LiDAR hardware for autonomous vehicles, to launch his own deep-tech startup called Hemanthes. This new company uses Raman spectroscopy and principles of Photonics to create robust biological datasets designed to train Artificial Intelligence models. By focusing strictly on hardware and data for AI, Evans aims to distinguish Hemanthes entirely from traditional diagnostic lab competitors like Quest and LabCorp, while avoiding the pitfalls of corporate deals like Theranos's failed contract with Walgreens.

Hemanthes: AI-driven Biological Data via Raman Spectroscopy
medium confidence
Technology Watchlist
Time horizon: long (The development and adoption of deep-tech hardware and AI data infrastructure typically requires significant time for R&D, scaling, and market penetration.)
Thesis

Billy Evans' new company, Hemanthes, could become a significant player in AI by providing high-quality biological datasets derived from Raman spectroscopy, differentiating itself from traditional diagnostics and avoiding the pitfalls of Theranos.

Rationale

Evans leverages his experience in photonics (LiDAR at Luminar) to build a new layer of sensors using Raman spectroscopy to create rich biological datasets for AI. This approach aims to be cheaper and more accessible than current lab equipment, focusing on data for AI rather than direct diagnostics.

Evidence
  • My background's in the photonics space. I helped build a company called Luminar. We built lidar for autonomous vehicles using lasers.
  • My company is called Hemanthes. We are building a new layer of sensors to better understand biology.
  • We use a technique called Raman spectroscopy in which we shine light through biological samples. It creates a scattering effect where the light changes color and then you you interpret uh what chemical structures are within that sample.
  • The problem is these devices are millions of dollars, many feet long, super complicated to use.
  • So, I'm taking a lot of the learnings from my work in the photonics space to to make these cheaper and widely distributed so we can give artificial intelligence uh really rich and deep data sets for biology.
  • Today, most things are built for human doctors to understand and we're trying to create really deep data sets that that artificial intelligence can use to create correlations between all these disparate signals.
Catalysts
  • Successful development and miniaturization of Raman spectroscopy devices.
  • Securing partnerships with AI companies or research institutions needing biological data.
  • Demonstrating the accuracy and cost-effectiveness of Hemanthes' data compared to existing methods.
Risks
  • The complexity and cost of Raman spectroscopy technology may still be a barrier to widespread adoption.
  • Competition from established players in biological data generation or AI model training.
  • The 'Theranos 2.0' narrative could create investor skepticism, despite the different business model.
  • Reliance on AI adoption and the need for deep biological datasets may take longer than anticipated.
Next Diligence
  • Investigate Hemanthes' current stage of development and funding.
  • Analyze the technical specifications and cost projections for their Raman spectroscopy devices.
  • Identify key competitors in the biological data for AI market.
  • Assess the adoption rate of AI in biological research and diagnostics.

Re-evaluating Elizabeth Holmes' Narrative and Legal Proceedings
low confidence
Macro
Time horizon: medium (The impact of the documentary and ongoing discussions about her sentence reduction and potential halfway house transition will unfold over the next year.)
Thesis

The public and media narrative surrounding Elizabeth Holmes may be incomplete, and a deeper understanding of the legal process, her adherence to judicial orders, and the distinction between patient and investor fraud could offer a more nuanced perspective.

Rationale

Billy Evans argues that Holmes was constrained by a gag order, preventing her from publicly defending herself against media narratives. He highlights her acquittal on patient fraud charges and the conviction solely on financial fraud related to investors, suggesting a distinction often overlooked in public discourse.

Evidence
  • Elizabeth was under a gag order through the trial and through the appeals process, which ended last April.
  • She was acquitted of patient fraud regarding millions of tests, she was convicted of financial fraud involving prominent investors.
  • The government brought forward four patients that they accused her of defrauding with inaccurate results. She was acquitted of those counts.
  • She was convicted of defrauding three investors and then colluding with her partner at the time to do so, so conspiracy.
  • The First Step Act... could allow her to transition to a halfway house sooner than expected.
  • The couple participated in an upcoming documentary directed by Nathan Fielder to counter the established media narrative and show her true character.
Catalysts
  • The release of the Nathan Fielder documentary providing a different perspective.
  • Potential future legal filings or appeals that could alter her sentence or conviction status.
  • Further analysis of the legal proceedings and sentencing guidelines, particularly regarding the 'conspiracy' charge and investor inclusion.
  • Public discourse shifting to acknowledge the nuances of the Theranos case beyond the initial media portrayal.
Risks
  • The 'gag order' was not a formal gag order, but a judicial instruction to litigate in court, not the press.
  • The distinction between patient and investor fraud may not mitigate the severity of the overall deception.
  • The documentary may not significantly alter the ossified public narrative.
  • The legal outcomes are largely settled, with limited avenues for appeal or retrial.
  • The focus on Holmes's personal narrative may overshadow the systemic issues in venture capital and biotech funding.
Next Diligence
  • Review the Nathan Fielder documentary upon its release.
  • Analyze court documents related to the Theranos trial, focusing on the specific charges and acquittals.
  • Research the First Step Act and its impact on sentence reductions for federal inmates.
  • Investigate the legal basis for including additional investors in the sentencing guidelines.
